Hi Andras,
Thanks a ton!

We are building a software that has a very specific purpose, other than the
visualization part, everything else is tailored to the demands. To make it
lightweight, we have to build a custom software. That's why we have taken
the more difficult approach. Otherwise, we would have chosen an open-source
solution.

Thanks again for pointing out the solution.

Many thanks.


Bill

I'm pleased to announce
VTKAda version 8.0.0 ?free edition ?release 01/07/2017VTKAda is Ada-2012 ?port to VTK (Visualization Toolkit by Kitware, Inc) and Qt5 application and UI framework by NokiaVTK version 8.0.0, Qt version 5.9.0 open source and vtkc.dll,vtkc2.dll,qt5c.dll(libvtkc.so,libvtkc2.so,libqt5c.so) were built with Microsoft Visual Studio 2015 ?in Windows (WIN32)and gcc ?in Linux ?x86-64Package was tested with gnat gpl 2017 ada compiler in Windows 10 ?64bit,Debian 8.5 x86-64
As a role ADA is used in embeded systems, but with VTKADA(+QTADA) you can build any desktop applications with?powerful 2D/3D rendering and imaging (games, animations, emulations) GUI, Database connection, server/client, Internet browsing and many others thinks.
VTKADA you can be used without QTADA subsystem?

Hi,
Thanks for the link, however this is not completely optimal for my case: 
- the input data for my case is not a contour, since the points do not
necessarily lie on the same plane 
- vtkVoxelContourFilter expects coordinates to be integer values, and when I
try the example the resulting surface does not completely "touch" the
original contours - as if its outline were somewhat smoothed. I need the
algorithm to produce a surface that exactly matches the input outline. 

Is there a name for a generic algorithm that produces a surface from a given
3D boundary (nonplanar)? 

Thanks and best regards, 
Rok

Subject: [vtkusers] vertex and voxel correspondence using vtkMarchingCubes
Message-ID: <201707012238004290730@gmail.com>

Hi, experts,

Is there any way that I can get the corresponding voxel of the vertices on the isosurface obtained using vtkMarchingCubes.

I want to map the intensity of each voxel to the vertex on the surface, I first transform the image into a volume with equal intensity and obtain its polydata representation using marching cube in vtk. How can I get the vertex-to-voxel correspondence?

Thanks a lot.

Subject: [vtkusers] Building medical imaging applications from scratch
Message-ID: <BY2PR0701MB1941F57B13C76A5C8E57A19CD8D00@BY2PR0701MB1941.namprd07.prod.outlook.com>

(changed the subject to reflect the slightly shifted topic of the discussion)

Need for a ?lightweight? application is a commonly cited reason for starting development of a medical application from scratch (using just VTK+Qt). However, most of the time this is not a well-founded reason.

For example, if you already use Qt and VTK, adding an open-source application framework (3D Slicer, MITK, etc. ? if it is not strictly medical application then there are several others, for example ParaView) increases the total amount of third-party libraries (in term of line of source code) by about 5%. This is very little price to pay for the hundreds of man-years of effort that went into development and testing of these frameworks. When you apply for regulatory approval for commercial applications, 3D Slicer is considered software of unknown pedigree, the same way as VTK, and other libraries that you may use. Overall, you get somewhat increased documentation work, but you can save several years of software development effort.

We find that with 3D Slicer you need to write approximately 0.01%-0.1% of application-specific code for a new medical application ? see this illustration: https://1drv.ms/b/s!Arm_AFxB9yqHr_hDpop7_CaxXoO4cA.

I know that it is more fun to just start to develop something from scratch, compared to learning from others; it is also useful for understanding details by getting first-hand experience, etc., but when the end result is important ? you want to have an application that clinicians can use, try a new method in the operating room, you want to release a product faster, etc. ? then it is hard to justify the duplicated effort.

I know that the VTK list is read by many people ? VTK developers, users, application developers. I would be interested in hearing about opinion and experiences of others. Not necessarily in the medical imaging domain: for example ParaView developers may see a similar trend of people developing custom scientific visualization applications from scratch, instead of customizing/extending ParaView.

Hi Andras,
Thanks a ton!

We are building a software that has a very specific purpose, other than the visualization part, everything else is tailored to the demands. To make it lightweight, we have to build a custom software. That's why we have taken the more difficult approach. Otherwise, we would have chosen an open-source solution.

Thanks again for pointing out the solution.

Many thanks.

The highlighted code lines perform point picking in world coordinates. If you need more information then read the entire class and related classes, maybe add a breakpoint and run it step-by-step in a debugger to see how it works exactly.

Playing with these, learning about low-level details is fun and useful experience. However, I would strongly recommend not to develop yet another DICOM viewer from scratch. There are several existing open source medical image computing and visualization applications that are used by thousands of people worldwide, they are used in operating rooms, used as a basis of FDA-approved products, have been around for several years, stable, feature-rich, etc. that can be extended to fit your needs. Most of them use VTK!

Hi Elvis,
I did give it a try. But still, it didn't work. I think I must have missed something since there mush have hundreds of people tried to do the same thing, getting the world coordinate from the vtk screen. The only way it worked so far is to use a world picker. All other ways would return different settings with z valued at 88 something. Where is the z value coming from? Does the actor add the z in the renderer?

Would someone know the correct way doing it give some advices?

Many thanks.

Could you try turning interaction off on the renderer you use for your
"foreground" objects. In my code I have:

    auto foregroundRenderer = vtkSmartPointer<vtkRenderer>::New();
    foregroundRenderer->InteractiveOff();
    foregroundRenderer->SetLayer(1);
    ...
    GetRenderWindow()->SetNumberOfLayers(2);

Hope that helps, it's the last idea I have :p

I did a google search for
non planar contour surface construction

and found nothing that processed non-planar contours

You can use vtkProbeFilter to do this, but if the surface was
extracted from the voxel volume, all values will be the same.

If you want to sample a different volume, here are two examples

Subject: [vtkusers] Hole filling - getting individual components
Message-ID: <1498945992223-5743851.post@n5.nabble.com>

Hi,

I have a model with holes in it, which I am able to fill with the
fillHolesFilter (thus getting the poly data with all holes filled).

However, I want to separate all the added surfaces (individual filled holes)
into separate polydatas, but I don't see this functionality in the
fillHolesFilter.

I was thinking about doing something by intersecting the original model with
the filled model, but I don't know what method to use and how to do it
efficiently. Does anybody know of a good way of doing this?

Thanks and best regards,
Rok

Do you need each hole or just all of the holes as a single component?
I think I have a solution. I'll post an example tomorrow.

Hi,

It would be preferable if they are separate but even if they are a single
component I can manually split them based on connectivity.

 Hi to all, this is my first post in the mailing list. I'm trying to develop a plot application thant is able to create the controuf similar to matlab https://it.mathworks.com/help/matlab/ref/contourf.html
I succeed in creating something like it but?my actual issues are place the plot in the center and?resize dynamically?with the window. This is the code that I'm using so far:

void CreateBaseData(vtkImageData* image)
{


    datastructure * dataInput = new datastructure(FILEPATH);


    image->SetDimensions(dataInput->shape()->Xsize, dataInput->shape()->Ysize, 1);
//    image->SetSpacing(dataInput->shape()->Xres,dataInput->shape()->Yres,0);


//    image->SetOrigin(dataInput->shape()->Xmin,dataInput->shape()->Ymin,0);


    image->AllocateScalars(VTK_DOUBLE,1);


    for(unsigned int x = 0; x <  dataInput->shape()->Xsize; x++)
    {
        for(unsigned int y = 0; y < dataInput->shape()->Ysize; y++)
        {
            double* pixel = static_cast<double *>(image->GetScalarPointer(x,y,0));
            pixel[0] = dataInput->z[y][x];
        }
    }
    delete dataInput;


    //image->Modified();
}


void RenderWindowUISingleInheritance::ModifiedHandler()
{
    ui->qvtkWidget->GetRenderWindow()->Render();
}




// Constructor
RenderWindowUISingleInheritance::RenderWindowUISingleInheritance(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::RenderWindowUISingleInheritanceUI)
{
    ui->setupUi(this);


    vtkSmartPointer<vtkInteractorStyleImage> style = vtkSmartPointer<vtkInteractorStyleImage>::New();


    ui->qvtkWidget->GetRenderWindow()->GetInteractor()->SetInteractorStyle(style);

Please include vtk users mailing list... Also I've changed the subject...

The gears have lots of long skinny triangles. I suspect this is
causing problems with the boolean algorithm.

Unfortunately, these Boolean filters in VTK are not reliable. Result mesh contains errors - parts missing, strange shapes are added - maybe in about 10% of the cases, even if triangles are not particularly skinny. By slightly changing the inputs we sometimes get correct results.



When we need something that works every time then we convert input meshes to images, perform Boolean operations on images, and convert the resulting image to mesh. Unfortunately, depending on the image resolution, this is a computationally expensive and somewhat lossy operation.

Subject: [vtkusers] How does VTK OSPRay-based volume rendering produce
	smooth images?
Message-ID: <CANm3fMaRjmQGkk_BBU4cdgF5KasC3hEiMmBuF1ddPkb6nD5YjA@mail.gmail.com>

Hello everyone,

I wonder how does OSPRay-based volume renderer in VTK, used in ParaView, is
able to produce volume images with smooth surface from the first pass
(without buffer accumulation).

OSPRay raw volume rendering e.g. using OSPRay demos, results in very densly
sampled volumes. It looks like only one sample per voxel is taken which
results in one pixel per voxel colored in the first pass at some regions
(image 1). Only after several accumulation passes the rendering produces
smooth image (image 3).

In contrast to that, volume rendering in ParaView via OSPRay shows smooth
image after first pass (image 4) with a little bit of densly sampled
artifacts. It actually looks like no frames accumulation is active at all,
because I no difference is visible between moving and resting camera.
Zooming in also keeps the image smooth (image 5).

Any articles or hints about what is going on behind the scenes? I'm digging
into the VTK source code but no understanding so far. OSPRay seems to be
configured just like I do in my application, but VTK seems to do the magic
somewhere else.

Screenshots or standalone OSPRay and ParaView-OSPRay renderings are
attachend.

Best Regards,
Alexander Devaykin

I don?t know about any good Boolean mesh operation implementation with BSD-type license. VTK got quite close to a working solution, so I think it would worth investing time into fixing the remaining problems.

Although in the past couple of years many people wanted to use this feature, nobody had enough resources to get these problems fixed. Maybe some kind of crowdfunding scheme would work?

Thank you Andras for your reply.
By the way, do you recommande any other library?

Unfortunately, these Boolean filters in VTK are not reliable. Result mesh contains errors - parts missing, strange shapes are added - maybe in about 10% of the cases, even if triangles are not particularly skinny. By slightly changing the inputs we sometimes get correct results.



When we need something that works every time then we convert input meshes to images, perform Boolean operations on images, and convert the resulting image to mesh. Unfortunately, depending on the image resolution, this is a computationally expensive and somewhat lossy operation.

There is new boolean filter that has been sitting in an MR for a year now:
https://gitlab.kitware.com/vtk/vtk/merge_requests/1752
I was asked to review it, but I don't do much mesh work.  I've only written
one mesh-generating algorithm in all my years with VTK.

So if anyone is interested in getting a better boolean mesh filter into
VTK, please try the one in the linked MR and let us know how well it works
for you.

I'll take a look at this MR. I'll try it on the user's challenging data.

Also, there is this one
https://github.com/seanm/midas-journal-726
But it uses a gpled library. Could be a candidate for a Remote module. I remember I tried it a few years back and it performed pretty well.

Hello,
Is there any way to visualize set of eigenvalues/eigenvectors using vtk?
For example, I have this data:
eigenvalues = (-22812140527.70874, -17173061888.51663 ,577143888297.0613)
eigenvectors = (-0.50657551,  0.04671729, -0.860929), (-0.01544831,
-0.99886247, -0.04511221),(0.86205719,  0.00955284, -0.50672097)

Subject: [vtkusers] Control VTK frame rate
Message-ID: <1499176466330-5743876.post@n5.nabble.com>

I had rendered actors to the render window. As I increase the number of
actors the frame rate decreases and the rendering is slow. Is there any
possible way to set the frame rate or increase the rendering speed as the
number of actors increase.

I tried to use ImmediateRenderingMode but I could not find any difference in
rendering speed/ Frame Rate.

I am trying to move the actor based on the input which is generated every
millisecond i.e 1000 datapoints for 1 second and apply it to the actors to
make a rotation.

Sample code that I use:

vtkSource s = new vtksource;
vtktransform t = new vtktransform;
vtktransformpolydatafilter tf = new vtktransformpolydatafilter;
tf->setinputconnection(s->getoutputport());
tf->settransform(t);
vtkpolydatamapper map = new vtkpolydatamapper;
map->setinputconnection(tf->getoutputport());
vtkactor act = new vtkactor;
act->setmapper(map);
while(true)
{
   t->Identity();
   t->RotateZ(SomeInputData); // SomeInputData changes every millisecond and
transform is in a loop
   t->update();   
   renderer->addActor(act);
   renderer->modified();
   renderWindow->render();
}

As the number of actors rendered to the same window increases the frame rate
decreases. 
I used renderer->GetLastRenderTimeInSeconds(); to get the frame rate (i.e
1/time)

Any solutions or suggestions would be helpful.
 Thanks for taking time to read the post.

Regards,
Kay

Basically you try to visualize a 3-by-3 symmetric matrix.
The natural choice is to use an ellipsoid.

Unfortunately, you have *negative* eigenvalues.
Therefore, the most elegant visualization should be this 
SuperquadricTensorGlyph
<http://people.cs.uchicago.edu/~glk/sqd/schultzTVCG10SuperquadricTensorGlyphs.pdf> 
.
The  code <http://web.ci.uchicago.edu/~schultz/sphinx/superquadrics.html>  
is based on OpenGL, rather than VTK.

Hope this could help or inspire you to some extent.

Longbow

Why do you need such a high frame rate? I don't think a human can really
perceive any differences at such high rates. 60 FPS or so is normally the
target to strive for (with monitors).

Thanks David, that did the trick.

However,while I was testing with the TestDragon example, the example built
successfully and while running the exe I got the following errors on the
vtkOutput Window:

WARNING :In C:\VTK\src\IO\PLY\vtkPLYReader.cxx,line 126
vtkPLYReader(004F5C00): Could not open PLY file

This is how my call to Open the file looks like:
const char* fileName =
    vtkTestUtilities::ExpandDataFileName(
      argc, argv, "C:/Users/User/Desktop/TestDragon/src/dragon.ply");

Have also tried:
const char* fileName =
    vtkTestUtilities::ExpandDataFileName(
      argc, argv, "dragon.ply");

But I still get the same result.
I am using the file dragon.ply file from
https://midas3.kitware.com/midas/download/?items=318673,1

Any ideas on how what is the issue?

By rendering more number of actor, I get a frame rate of 7-9 but i am trying
to improve it to 12-14. And I get no where near 60 FPS though my display
settings are set to 60. At frame rate of 7-9 and 12-14 there is huge visible
difference, which I am trying to improve.

I think I use more than sufficient hardware configuration. My hardware
configuration 32GB RAM, 4GB NVIDIA M2000M Graphic Card, Core-7i processor

Regards

Make sure you are using the openGL2 backend.

More importantly, avoid using multiple actors. They are heavyweight objects
and won't support high rates for more than perhaps a few hundred instances.
Instead use appendpolydata or something similar to bring everything
together into one or a handful of actors.

I am using the latest version of OpenGL backend. 

I could consider combining polydata to use fewer actors as you suggested.
But each of the actor perform transforms like rotation and translation
independently of other.

Your display settings have nothing to do with how well VTK can perform.

What I meant was: Why are you moving your actor at such a high
frequency (1000 times per second)? To me it doesn't make sense to try
to move it that often (you're probably swamping VTK with render
requests).

I would try to move it maybe 60 times per second, or at least in that ballpark.

Where are these high frequency events coming from?

If you by any chance is using Qt 5.5, and these are mouse/touch
events, you could be suffering from QTBUG-40889 (fixed in 5.6).

All:

Is it possible to load a VTK from memory (string), or would I need to implement a new reader class for this?

Message-ID: <1499199997785-5743885.post@n5.nabble.com>

My Input data is generated by the realtime system, so the high frequency of
data. But the VTK application I am trying to build is not a real time
system. To explain further, the pseudo code that I posted before works by
calling render in a loop.

double realTimevariable; // This variable is updated by the real time system
every millisecond
while(true)
{
   t->Identity();
   t->RotateZ(realTimevariable); // realTimevariable takes the value at this
point of time
   t->update();  
   renderer->addActor(act);
   renderer->modified();
   renderWindow->render();
} 

Each time the loop is run value of the realTimeVariable is taken from the
memory at that instance of time.
This process works for less number of actors and frame rate is 12-14, but if
the actors are doubled the frame rate goes down by 7-9 which is visible to
the eye. From what I understand, this looping of render call
(renderWindow->Render();) is what you mentioned "swamping VTK with render
requests", Please correct me if I am wrong.

And I dont want to control data to 60 times per second, as I want VTK to
render as often as it can (Minimum of 12 FPS)

I am not using QT, just basic vtk pipeline in C++.

How many actors do you have?

If I use 120 Actors I get a frame rate of 12-14, 
but if I use more than 240 I get a frame rate of 7-9

And all the actors are loaded from STL/OBJ files

The actors are loaded with data from STL/OBJ files only once, but the
transform like rotation are make the actors to change every time the loop is
run.

I don't recommend it.  It depends on libGTS, which, besides licensing issues, has not seen a release in over 10 years:

<http://gts.sourceforge.net>

There's clearly no future there.  :(  Besides, we were using it, and found it crashed a lot.  We've had better luck with VTK's class, but it too crashes on occasion and gives wrong results.

Cheers,

Sean,

Thanks for the evaluation. I agree. I think the LoopBoolean looks like a good way to go.

Are they transformed independently or in unison? Also, how is the transformed applied? In the pipeline, or directly to the actor?

Transforms are independent and are applied directly to the actor

That seems to rule out Appending the models.  Are you using SetUserMatrix on the actors? Also, use a SetInputData on the mappers after Updating the last filters in the pipeline.

Hi all,

You might try the vtkGlyph3DMapper. It can take in a bunch of "source" polydata objects plus a set of points with point-data specifying orientation, scaling, and the index of which polydata to draw at each point. More recently, David Lonie added a way for it to take in a multiblock dataset and let each point specify the index of a top-level block to render (again, with point-data specifying per-instance transforms).

That would leave you with a single actor and an easy way to update per-instance transforms.

	David

Subject: [vtkusers] problems with multithreading in VTK with winforms
Message-ID: <1499207915344-5743896.post@n5.nabble.com>

Hello all. I have a couple problems trying to do multithreading with VTK
using winforms. Currently I have a form with a pictureBox and a
RenderControlWindow, where the pictureBox is used for streaming data while
the RenderWindow is used to display images on the side. From some previous
reading, I've tried to implement a solution where updates to my image are
done on one thread and the rendering is done on the main form thread. The
problem is that when I try to re-render the window itself doesn't change.
Some code below, at least what I think might be relevant can post more if
need be.

Update Thread:
            vtkImageImport imageImport = null;

            o = new Thread(() =>
            {
                byte[] myByteArray = new byte[data.Size];
                int idx = 0;

                for (int k = 0; k < D; k++)
                {
                    for (int j = 0; j < H; j++)
                    {
                        for (int i = 0; i < W; i++)
                        {
                            idx = k * W * H + j * W + i;
                            myByteArray[idx] = (byte)data.Get(idx);
                        }
                    }
                }

                // Copy byte array into VTK

                imageImport.SetNumberOfScalarComponents(1);
               
imageImport.SetImportVoidPointer(gPointer.AddrOfPinnedObject());
                imageImport.Update();

                renderer.Modified();
                renderer.Render();
            }

        }


Another curious thing is that if I run this normally the renderWindow
doesn't change, but if I run it while debugging it seems to work fine and
the window changes to what it should be.

Any help or insight would be greatly appreciated. Thanks!

                                      Regards,
                                          Neel

Subject: [vtkusers] dynamic sectioning class
Message-ID: <CAGOvywbGFKARowidF8VH6FK_LfswDPjqiLGoR_=C-ANkY70S_A@mail.gmail.com>

Hi Experts,

Is there any class in VTK library which provides dynamic sectioning for
selected object (such as 3D Image volume data or Surface objects).

Dynamic sectioning is used to create a section through a part/ assembly.
This can be useful when you have a complex project and want to see hidden
details.
Clicking on different surfaces on the 3D model allows us to view the
section from different angles.

Left clicking and holding on the red cross representation allows the plane
of the section to be moved to different depths.
For e.g

See attached images.

thanks & regards,
Girish

Directly put the file path in
 reader->SetFileName();
And it removed the error.

However it is still giving the Failed to Create LibOVR session error, even
though it is launching the Oculus App at the background.

Any thoughts?

Subject: [vtkusers] Multiview port dicom viewer zoom in problem
Message-ID: <CANuVs=J=o9nYwpLa2qD1W5Rczycy1=o1kHvxY8a0ytMG0K1-ug@mail.gmail.com>

Hello,
I have created a multi view port (6 viewports in one window) mri dicom
viewer for displaying a list of DICOM files in a single window in Qt.
I used vtkDICOMReader, vtkImageActor, vtkImageSliceMapper and QVTKWidget.
The DICOM images are displaying as expected but have two issues.

1) Main issue is, while zooming in the images in view ports, after a
particular level of zoom the images disappearing. But after zoom out to the
previous particular level the image reappearing again. This happening in
case of all the view ports.
Also no issue for zoom out.

2) The images are displaying in smaller size than the view ports size.

Why this happening? Please help..

My code something like this, and attached few screen shots

vtkSmartPointer <vtkDICOMDirectory> m_vtkDcmDir;

vtkSmartPointer<vtkDICOMReader> m_vtkDcmRdr
vtkSmartPointer<vtkDICOMReader>::New();

vtkSmartPointer <vtkStringArray>  m_aVtkStrFNames;

QVTKWidget m_vtkWgtWin;  m_vtkWgtWin = new QVTKWidget();



m_vtkDcmDir->SetDirectoryName("E:/Projects/mri/evaluate/Qt/ImageViewer/VTK/VTKtest/ReadDICOM/DICOMSeries");

    m_vtkDcmDir->*Update*();

    // Iterate through all of the studies that are present.

    m_iNoStudies = m_vtkDcmDir->GetNumberOfStudies();

    for(int i = 0; i < m_iNoStudies; i++)

    {

        int j1 = m_vtkDcmDir ->GetFirstSeriesForStudy(i);

        int j2 = m_vtkDcmDir ->GetLastSeriesForStudy(i);

        for (int j = j1; j <= j2; j++)

        {

            m_aVtkStrFNames = m_vtkDcmDir->GetFileNamesForSeries(j);

            // do something with the files

            m_vtkDcmRdr ->*SetFileNames*(m_aVtkStrFNames);

            m_vtkDcmRdr ->*Update*();

        }

    }



// Define viewport ranges

    double xmins[6] = {0, .33, .66, 0, .33, .66};

    double xmaxs[6] = {.33, .66, 1, .33, .66, 1};

    double ymins[6] = {0, 0, 0, .5, .5, .5};

    double ymaxs[6]= {.5, .5, .5, 1, 1, 1};

    for(unsigned i = 0; i < 6; i++)

    {

        vtkSmartPointer<vtkImageActor> imageActor = vtkSmartPointer<
vtkImageActor>::New();

        imageActor->*SetInputData*(m_vtkDcmRdr->GetOutput());

        vtkSmartPointer<vtkImageSliceMapper> imageMapper =
vtkImageSliceMapper::SafeDownCast(imageActor->*GetMapper*());

        imageActor->SetMapper(imageMapper);

        imageMapper->SetInputData(m_vtkDcmRdr->GetOutput());

        imageMapper->*SetSliceNumber*(i+1);



        vtkSmartPointer<vtkRenderer> vtkRen = vtkSmartPointer<vtkRenderer
>::New();

        vtkRen->*SetViewport*(xmins[i],ymins[i],xmaxs[i],ymaxs[i]);

        vtkRen->AddActor(imageActor);

        vtkRen->*ResetCamera*();

        m_vtkWgtWin->*GetRenderWindow*()->*AddRenderer*(vtkRen);

    }



     m_vtkWgtWin->*GetRenderWindow*()->*Render*();

    m_vtkWgtWin->update();

    m_vtkWgtWin->show();

Hi, I authored the LoopBoolean a few years ago because we wanted a more
reliable vtk-based boolean to use in our software. 

I've mentioned this before I believe on the merge requests, but I think it
may be helpful to say it again here. When the booleans fail (current and the
LoopBoolean), it is typically during re-triangulation due to vtkDelaunay2D.
I developed the LoopBoolean using vtk 6.0. After vtk 6.0, some changes were
made to the vtkDelaunay2D code, which caused many more issues in the
LoopBoolean. I tried working with the vtkDelaunay2D author to fix some of
the Delaunay bugs, and we got a couple fixed, but a few remain.

So, in our software, we actually have a copy of the vtkDelaunay2D code from
the vtk 6.0 pipeline, and the LoopBoolean calls that. The code works well
for our purposes. It still isn't bug free as the code is tolerance-based,
and there are orientation tests that may fail from time to time due to
tolerance issues. Also, I'll admit that error checking could be better. I
would like to go back and improve this part of the code, but haven't had the
time yet.

Adam

That doesn't seem to match the pseudo code you posted, where the transform
is applied to a filter (shared by all the actors, well the only actor).
Maybe an updated bit of pseudo code would help.

In general with lots of actors you want to make sure

        mapper->StaticOn();

and

    ren->RemoveCuller(ren->GetCullers()->GetLastItem());

make sure it is a release build, and make sure your transformation is
happening on the actor, not a filter such as trransformpolydata.

The *.vtk (legacy) and *.vt? (xml) readers should support this via
SetInputString and ReadFromInputStringOn() methods from their parent
classes.

Other file formats that vtk has readers for may or may not have the
capability yet.

Thank you Ken Martin.

I could not post all the code, as the system is huge. Sorry that I missed
some parts in pseudo code.
Hope you understand.

Making these changes had increased the frame rate from 7-9 to 16-17.
This fixed the low frame rate.

You post has really helped me
Thank you Ken Martin for the time

Regards,
Kay

The code snippet confuses me as well, since it looks like a new actor is
added to the renderer in each iteration of the while(true). If that's true,
the number of actors would grow fast and unboundedly.

Unless I'm missing something here.

The instability of vtkDelaunay2D is definitely a problem for these kinds of
filters.  It isn't just a matter of vtkDelaunay2D having bugs... the
problem is that in order for the algorithm to be robust, it must use exact
math.  So a lot of the work that has gone into fixing bugs seems to have
just changed the situations that cause it to crash.

A few years ago I wrote a filter called vtkContourTriangulator that can
sometimes be used as a stable replacement for vtkDelaunay2D.  However,
vtkContourTriangulator is not as fast as vtkDelaunay2D, nor does it produce
high-quality triangles (i.e. it does triangulation, but not Delaunay
triangulation).

It's worth mentioning that I quickly tried swapping vtkContourTriangulator
in place of vtkDelaunay2D a while back, but didn't quite get it to work. I
didn't spend a lot of time on it, though, so it may be worth investigating
again if someone wants to try. The quality of the triangles isn't that
important for the boolean operations IMHO, and you can get some high-aspect
ratio triangles with the constrained Delaunay triangulation that the
boolean operation filters currently use.

We (Rogue Research) spoke to Kitware about contracting them to get BooleanOperationPolyDataFilter working better.  I've been waiting for my boss to send off the paperwork... I'll give him a kick today, as I'd really like to see this class working better! :)

Message-ID: <a3e59671-c85e-040c-efd3-565433ed2b21@geomod.ch>

The class vtkInteractorStyleRubberBandPick allows selection of a 
rectangular window, when 'r' is pressed, and selection of a 1x1 window, 
when 'p' is pressed.

1) Is there a way to get the key that is currently pressed (the current 
selection mode)?

2) Is it possible to set the selection mode 'r' or 'p' in the code (i'm 
using pyqt and would like to choose the mode by checking a box in a gui)?

Hello,
I'm inheriting  vtkInteractorStyleImage for customizing mouse events in an
image viewer.
In vtkInteractorStyleImage, have any method to get the details of which
mouse button is pressed(Left/ Right/Middle) like GetKeySym() for keyborad
 keys.
I know about the virtual functions like OnRightButtonDown
<http://www.vtk.org/doc/nightly/html/classvtkInteractorStyle.html#a41fd8967b8537a29e68d614990006ee1>
 ().
Have any direct way to get from the vtkInteractorStyleImage  object...?

Most likely the only difference is that VTK sets up OSPRay's volume
sampling differently than the OSPRay demos do.
You will find how it is setup here:

https://gitlab.kitware.com/vtk/vtk/blob/master/Rendering/OSPRay/vtkOSPRayVolumeMapperNode.cxx#L255

Note also: starting with ParaView 5.3, if you start ParaView with
--enable-streaming, and set "Progressive Passes" on the Properties panel to
something higher than one, ParaView will do progressive refinement like you
see in the OSPRay demos.

Subject: [vtkusers] Compatible version of Twisted and AutobahnPython for
 vtkWeb in VTK 8.0.0

Hi!
VTK uses a 'third-party' repo with an import of some other libraries. You
can look there for specific versions that match different VTK versions. VTK
8 uses a pretty up-to-date Twisted (17.1 or 2?) but a much older Autobahn
with some Python 3 compatibility code back-ported. Here's the repos:
https://gitlab.kitware.com/third-party

Regards,
Aron

Subject: [vtkusers] Separating actors for different render passes
Message-ID: <C745C1E748CE104AA373B656E0EF5E30E96ABC8A@ex14mb4.win.rpi.edu>

Is there currently a way to separate actors into custom render passes? If I'm not mistaken, opaque objects currently get rendered before translucent objects, but is there a way to add additional geometry passes (or before opaque geometry, or between translucent and opaque geometry, etc.)?

With the render passes you can setup as many passes as you want in whatever
order you want. This shows an example where the render process is all
driven by passes.

https://gitlab.kitware.com/vtk/vtk/blob/master/Rendering/OpenGL2/Testing/Cxx/TestSobelGradientMagnitudePass.cxx

As an example for shadow maps when needed we use nested opaque passes to
render the scene from the view of the light sources which we then use in
another opaque pass to compute lighting from the view of the camera.

Render passes also have hooks that mappers call so that passes can modify
the mapper shader code etc while executing.

Passes can also use information properties on actors to filter them in
other passes.  For example an outer render pass can add information on
actors that causes some of them to not be rendered (or to be rendered
differently) by other passes ala

//
----------------------------------------------------------------------------
// Description:
// Opaque pass with key checking.
// \pre s_exists: s!=0
void vtkDefaultPass::RenderFilteredOpaqueGeometry(const vtkRenderState *s)
{
  assert("pre: s_exists" && s!=0);

  int c=s->GetPropArrayCount();
  int i=0;
  while(i<c)
  {
    vtkProp *p=s->GetPropArray()[i];
    if(p->HasKeys(s->GetRequiredKeys()))
    {
      int rendered=

p->RenderFilteredOpaqueGeometry(s->GetRenderer(),s->GetRequiredKeys());
      this->NumberOfRenderedProps+=rendered;
    }
    ++i;
  }
}

Message-ID: <CAHJpOURdJW_6rAK7hTe-zNiOQPMrQcQaUQV36-q0M+VDC4GnBQ@mail.gmail.com>

Hi,

I want to use VTK plane to cut the polydata  using mouse. CUrrently I can
place the plane and cut the polydata using the plane using some keypress.
Now i want to use the Plane widget and as soon as i stop placing the plane
near the polydata, the plane should cut it. I have tried with Callback with
LeftButtonRelease event , and OverRiding the LeftButtonUp methods. But these
methods are not working correctly. Anyone with a good idea?

Thanks

To: Andreas Buykx <A.Buykx at dianafea.com>


The default culler checks the bounding box of every actor/prop and if they
are outside of the view frustum it does not render them. So the performance
question becomes:

is checking the actor's bounding box (with the pipeline mtime check) faster
than the time savings of sometimes not rendering the actor?

So when the actors will all typically be visible and there are lots of them
(or their filter pipelines are long) removing the culler can save time
because you may be CPU bound on checking pipeline mtime. Oddly enough
checking pipeline mtime can be fairly time consuming for lots of
pipelines/actors.  So making the mapper static and removing the culler
basically cuts out all pipeline mtime checks reducing the CPU load which
with a fast GPU the CPU can often be the bottleneck for lots of VTK actors.

Dear All,
Can I use vtkcutter (or any other method) to get a slice of a vtkpolydata (for slicing MRI volume to get 2D), the way vtkimagereslice gives output form a volume Image data?
The reason I want to be able to reslice polydata is that later I want to do other operations on it.
Thanks for the help.

Hi

I am using vtkPlanewidget , but once the next frame is loaded its handles
disappear.
it will appear only if i call Off() method and On() method
the problem is, I am using them with callback, hence once i press mouse,
entire widget will disappear for Off() and appears for On().
I want the handles to be available for all frames. is there a way just to
turn on handles every frame?

Thanks.

Subject: [vtkusers] Using Volume Renderings Piecewise opacity function with
 vtkImageViewer2
Message-ID: <1499475231119-5743930.post@n5.nabble.com>

Currently I am using vtkImageViewer2 to display the slices of a volume. Works
alright but doesn't handle rotations all that well. Right now I want to
apply my transfer function used in volume rendering to these slices. To do
this I could simply give the vtkColorTransferFunction to the image actors
property and it would work like so:

imageViewer->GetImageActor()->GetProperty()->SetLookupTable(colorTransferFunction);

Now I'm looking to apply the opacity as well which is defined separately as
a vtkPiecewiseFunction. Is there an easier way to do this without manually
creating a lookup table from the two functions?

Hi juanibv,

Employing vtkPriorityQueue is relatively simple method of sorting
vtkPoints by one coordinate. I attached a sample.

You can use ImplicitPlaneWidget2 to do this. The following example may

Thanks Ken! This is just what I was looking for. A couple of followup questions:

1. Is it possible to have an actor with different shaders for different passes? Or would we need to use separate actors/mappers since each mapper only has one shader? Recompiling shaders on the fly isn't an option for us.
2. Is it possible to replace the default vtkDefaultPass for the vtkRenderer with a different subclass of vtkDefaultPass or at least disable the default vtkDefaultPass? I couldn't find any API commands that would allow me to do this without subclassing the vtkRenderer, but I could've missed something.

Subject: Re: [vtkusers] Separating actors for different render passes

With the render passes you can setup as many passes as you want in whatever order you want. This shows an example where the render process is all driven by passes.

https://gitlab.kitware.com/vtk/vtk/blob/master/Rendering/OpenGL2/Testing/Cxx/TestSobelGradientMagnitudePass.cxx

As an example for shadow maps when needed we use nested opaque passes to render the scene from the view of the light sources which we then use in another opaque pass to compute lighting from the view of the camera.

Render passes also have hooks that mappers call so that passes can modify the mapper shader code etc while executing.

Passes can also use information properties on actors to filter them in other passes.  For example an outer render pass can add information on actors that causes some of them to not be rendered (or to be rendered differently) by other passes ala

// ----------------------------------------------------------------------------
// Description:
// Opaque pass with key checking.
// \pre s_exists: s!=0
void vtkDefaultPass::RenderFilteredOpaqueGeometry(const vtkRenderState *s)
{
  assert("pre: s_exists" && s!=0);

  int c=s->GetPropArrayCount();
  int i=0;
  while(i<c)
  {
    vtkProp *p=s->GetPropArray()[i];
    if(p->HasKeys(s->GetRequiredKeys()))
    {
      int rendered=
        p->RenderFilteredOpaqueGeometry(s->GetRenderer(),s->GetRequiredKeys());
      this->NumberOfRenderedProps+=rendered;
    }
    ++i;
  }
}

The passes can modify a mapper's shader but a mapper does not store shaders
per pass.

VTK caches and shares shaders between mappers so once a given shader
program has been used once it will be not recompiled for the duration of
the run.

When you specify a render pass on the renderer, whatever render pass you
specify takes full control of the render process and the default process is
skipped.

Subject: [vtkusers] segfault with MarchingCubes
Message-ID: <CAPyYnjXo-ihmccpf0f9+6StK9J66nQd_7QzE_AvzRgMfCZXFdA@mail.gmail.com>

Hello all,

I am trying to use the Marching Cubes algorithm to show a 3D surface of a
3D image given by a Python (numpy array).
I thought I had it all mapped out, things were going great with arrays of
small size (generated and rendered 3D isosurfaces), but now that I'm
working with arrays of slightly bigger size, the programm crashes with
Python error 11 SIGSEGV which means seg fault. What worries me a bit is
that the array I'm using is not that big, 150*150*150, and I have a fairly
recent computer who shouldn't have any problem handling it.

Code MWE is below (in Python)

=========================================== Code snippet
=======================

import numpy as np
import vtk

# Creating a numpy array representing a 3D image
npa=np.zeros((150,150,150)).astype(np.uint8)
npa[100:102,100:102,100:102]=255

# Importing it as  object vtk (based on vtk example
http://www.vtk.org/Wiki/VTK/Examples/Python/vtkWithNumpy)
dataImporter = vtk.vtkImageImport()
dataString = npa.tostring()
[hh, ww, dd] = npa.shape
dataImporter.CopyImportVoidPointer(dataString, len(dataString))
dataImporter.SetDataScalarTypeToUnsignedChar()
dataImporter.SetNumberOfScalarComponents(3)
dataImporter.SetDataExtent(0, dd - 1, 0, ww - 1, 0, hh - 1)
dataImporter.SetWholeExtent(0, dd - 1, 0, ww - 1, 0, hh - 1)
dataImporter.Update()
vol = dataImporter.GetOutputPort()
# (print(dataImporter.GetOutput().GetClassName()) yields "vtk.ImageData")

# Use MarchingCubes to generate iso-surface
surface = vtk.vtkMarchingCubes();
surface.SetInputConnection(vol);
surface.ComputeNormalsOn();
surface.ComputeScalarsOn();
isoValue = 128
surface.SetValue(0, isoValue);

#This line causes segfault if npa is "too big"
surface.Update();

# .... rest of pipeline
# decimator = vtk.vtkDecimatePro(); ....
# smoother = vtk.vtkSmoothPolyDataFilter(); ....
# connectivityFilter = vtk.vtkPolyDataConnectivityFilter(); ....
# mesh = vtk.vtkPolyData(); ....
# mapper = vtk.vtkPolyDataMapper(); ....
# actor = vtk.vtkActor(); ....


=========================================== End of code snippet
=======================



So I have a couple of questions here :
1/ Is this a problem of input for MarchingCubes being too big ? Or is this
segfault indicating something else ?
- arguments for the former : Reducing the size of npa in this code makes it
work
- arguments for the latter : This code I'm showing is a MWE for my code
which is more complicated, and in my code, this code portion fails with a
large array, but succeeds if I reduce in size *another* array which has
nothing to do with MarchingCubes() (again, that other array is not that
big, so I don't think I'm reaching the limits of Python memory or anything
like that...)

2/ Am I doing the whole import numpy thing correctly ? I've based myself on
the vtk example, but I am unsure of whether it is the recommended way for
my case or if it was case specific


Thanks everyone,
Cl?ment

The reason I want to be able to reslice polydata is that later I want to do other operations on it.
Thanks for the help.

Hi,

I'm trying to call Mouse wheel backward callback event to update image on
vtk window.

In my UI , there are 3 WPF controls and 1 vtk window. 

<http://vtk.1045678.n5.nabble.com/file/n5743938/Capture.png> 

when i perform mouse wheel operation on vtk window , image gets update.
Its,s fine.
But when i perform mouse wheel on WPF controllers, image on VTK window also
gets updated. 

I don't want to update image when i'm scrolling on WPF controllers.

If anybody knws plz help!!!!!

Regards,
Satwik

Hi Cl?ment,

The "number of scalar components" should be 1 for your data:

  dataImporter.SetNumberOfScalarComponents(1)

There are a couple places where you can improve efficiency:

  # directly create an array of the desired type
  npa=np.zeros((150,150,150), np.uint8)

  # directly pass the array to VTK (without tostring())
  dataImporter.CopyImportVoidPointer(npa, npa.size)

Cheers,
 - David

Great David, thanks again.
The SetNumberOfScalarComponents(3) was indeed a residual of a
not-careful-enough copy-paste from another part of the code.
Everything's working now, and thanks for the optimisation tips !

Message-ID: <2053204549.2490494.1499694689265@mail.yahoo.com>

Hello to everyone,
I have a 4x4 transformation matrix which I am using for Image Reslice and it works fine. Now I want to know how to rotate this matrix 90 degrees around an arbitrary axis so that I can reslice image in the new direction?

When I use vtkTransform as:
vtkSmartPointer<vtkTransform> Transform= vtkSmartPointer<vtkTransform>::New();??? Transform->SetMatrix(OriginalMatrix);
????Transform->RotateWXYZ(90, ArbitraryAxis);??? Transform->Inverse();
??? Transform->Update();
??? Transform->GetInverse(NewMatrix);
It does not give me the right matrix.

Can anybody give me a hint on where to start?
Thanks.

Subject: [vtkusers] Best way to visualize a RGB Volume?
Message-ID: <1499698015709-5743942.post@n5.nabble.com>

Hi,

i want to visualize a RGB Volume and have a little problem. i do not think
that there is a perfect solution, but maybe i am missing something. 

Here i my problem:

There are three different Methods to visualize a RGB Volume:
1. Method: IndependentComponentsOn: three components (R,G,B), each with
Colortransferfunction and opacityfunction
2. Method: IndependentComponentsOff: two components, first with
Colortransferfunction and second with opacityfunction
3. Method: IndependentComponentsOff: four components, 1-3(R,G,B) with
Colortransferfunction and fourth with opacityfunction

Here are the disadvantages for each Method:
1. Method: It is not possible to create a colorTransferFunction or
opacityFunction for the intensity value of a color(voxel), it is only
possible to set these functions for each components seperate. This can lead
to  	falsified colors if the user changes these functions somehow (if you
have the same color and opacity function for all components).
2. Method: the two components must have the same data type. the color
component needs at least 3 byte, but there is no 3 byte type => 4 bytes for
each component => 8 bytes per voxel => huge overhead.  Moreover the image
quality for maximum intensity BlendMode is not as good as for the 1. Method.
If you have (in the volume)  for example a green wall with value 250 and a
red area behind it (for the current camera position) with value 200, you
can't see the red area at all. In the first method the red area is displayed
as yellow area (that is better).
3. Method: No colorFunction

Is there a Method without disadvantages?

MfG
Ludwig

I don?t think so. You?ll have to create a lookup table manually from the
two functions.

Hi Ludwig,

Just so I understand, you?d like to be able to pass the RGB volume through
a color lookup table too?

IMHO, if you have a RGB volume, adding a fourth component for opacity and
setting an opacity function with IndependentComponentsOff is the best
method.

*Note* that with two dependent components, the first component values are
used to lookup colors from the color transfer function i.e. the first
component can be as small as 1 byte (unsigned char).

Hth,
Sankhesh

Perhaps, you could take a look at the ImplicitPlaneWidget2

example for using a plane to clip a polydata?

two components: if i use 1 byte for the first component i can only see 256
different colors, but i have  2^16 colors. I would need 8 byte to display
that (4 per component)
four components: just 4 bytes in total, but no color function.

As far as I know there is tensorglyph in vtk that allows to visualize
superquadrics. I've tried to use it but it gives me incorrect glyph. It
always gives me sphere instead of ellipsoid.

Rustem,
Indeed there is a superquadric source in VTK and ParaView. You can try this
source in paraview to see what paramters you need to specify to get the
glyph you want.

Subject: [vtkusers] VTK Surface & Volume Intersection Question
Message-ID: <1499792469848-5743953.post@n5.nabble.com>

Hi VTK Users,

So currently I have a vtkVolume created from DICOM slices.
On the other hand, I also have a vtkSphereSoure->vtkActor which is tracking
the motion of my mouse.

I was wondering if there was a way to detect when the vtkActor and vtkVolume
intersect. I don't need to exactly know how they intersect or the points
that intersect themselves - just when they intersect, like a boolean of
sorts.

Originally I was thinking that maybe I could just get the center position of
the sphere in my application loop and check if that point lies within the
rendering of the volume but I'm not sure if that's the best method, nor if
there are any VTK classes for that. I was wondering if there are any VTK
classes that can already do this or would i have to manually do it.

I was looking through a couple examples and they seem to all deal with
vtkPolyData and not a volume itself.

I would appreciate any help.

Regards,
Teek

I am adding more details to this question.
Basically I am comparing two polydata sets (target and source). These are STL files with triangular facets. I am comparing the polydata sets in the following way:?1. Using the ImplicitPolyDataDistance function to get the distance from a point on the source to target polydata. I use this to find the distance ?at mouse locations. This works perfect.2. Creating cross-section contours of source and contour using the vtkCutter and visually compare the contours.
However, I want to the source contour to be within + or - 0.2mm tolerance from target contour. It would be easy for me if I have two more contours with +0.2 offset and -0.2 offset from the target contour. This makes my visual comparison easier.
I tried to render the target contour with 0.4 thickness which solves this problem partly, but when I zoom in, the thickness does not change.
Appreciate your feedback. Thank you.

Subject: [vtkusers] Plotting animations of VTK timeseries
Message-ID: <1499956321124-5743962.post@n5.nabble.com>

I have an FEM program that ouputs time series of unstructured grid vtk files
with file extensions corresponding to the time steps. Currently I use
paraview to open and visualize animations generated from the various scalar,
vector and tensor data contained within these vtk files. The issue is that
in Paraview it is difficult or not possible to visualize 2 or more data
animations (based on vtk time series) simultaneously.

In the work I do it will soon become necessary to run dozens of calculations
and output dozens of vtk timeseries simultaneously. Each timeseries would
contain a hundred or so vtk files and would correspond to an independent
Paraview model to look at and analyze.

I would like to figure out whether there is a programmatic way to load up
these vtk files, filter them accordingly (applying for example the same data
filter) and visualize all animations on one window, perhaps attaching a
little tag to each animation so that I know what I'm looking at. 

Of course this could be quite demanding on the processor so I'm OK with
saving the "batch animation" containing all my different models and
visualizing it after the saving is done.

Any ideas on how one may accomplish this? Thanks.

Subject: [vtkusers] vtkDICOMImageReader(): Anyway to change the metadata?
Message-ID: <C9C21D89-AE7D-47AB-A0CA-867A1E677075@ryerson.ca>

Hello! 

This is my first post in this community and just as a heads up I am a complete newbie. I am currently working on a project to segment ventricles from MRI scans of the brain (in MATLAB). I wanted to then extract the surface using vtkDiscreteMarchingCubes() and write it into an STL file using vtkSTLWriter(). 

My problem is with the PixelSpacing, the documentation says if there are multiple DICOM images then the 'z' value is the Spacing Between the Slices. But I am receiving (0.859375, 0.859375, 0.0). I don't know why it is giving me a 0.0, it should be a 5. I have tried with an single DICOM and it works properly it gave me a Slice Thickness which coincidentally is the same value as the Spacing Between the Slices. 

SO MY QUESTION IS: is there anyway to manually change the value? My code is down below, THANKS FOR YOUR HELP! 

import vtk 

PathDicom = "./DICOMs/" 
reader = vtk.vtkDICOMImageReader() 
reader.SetDirectoryName(PathDicom) 
reader.Update() 

print(reader.GetPixelSpacing()) 

dmc = vtk.vtkDiscreteMarchingCubes() 
dmc.SetInputConnection(reader.GetOutputPort()) 
dmc.GenerateValues(1, 1, 1) 
dmc.Update() 

writer = vtk.vtkSTLWriter() 
writer.SetInputConnection(dmc.GetOutputPort()) 
writer.SetFileTypeToBinary() 
writer.SetFileName("ventricle.stl") 
writer.Write()

Hi Sonam,

The filter vtkImageChangeInformation can modify the spacing of the data:

ici = vtk.vtkImageChangeInformation()
ici.SetInputConnection(reader.GetOutputPort())
ici.SetOutputSpacing(0.859375, 0.859375, 5.0)

Subject: [vtkusers] Issues with rendering streaming 3D data
Message-ID: <1499992203443-5743967.post@n5.nabble.com>

Hi all. I'm trying to render streaming 3d data and I have a couple questions. 

1) Does anyone have experience doing this and if so how did you structure
your code to update data and render it, and how fast was it?

2) I have some code that does work for about a couple seconds before I get
an exception in Kitware.VTK.dll as I'm using ActiViz. If I take out the
render call in the code below, it seems to be ok. It only seems to have a
problem rendering. 

                try
                {
                    byte[] myByteArray =StreamObject.Bytes;

                    GCHandle gPointer = GCHandle.Alloc(myByteArray,
GCHandleType.Pinned);
                   
imageImport.SetImportVoidPointer(gPointer.AddrOfPinnedObject());
                    imageImport.Update();
                    imageImport.Modified();

                    // Set up renderer
                    vtkRenderer renderer =
renderWindowControl1.RenderWindow.GetRenderers().GetFirstRenderer(); 
                    //renderer.ResetCamera();

                    // Create transfer mapping scalar value to opacity
                    vtkPiecewiseFunction opacityTransferFunction =
vtkPiecewiseFunction.New();
                    opacityTransferFunction.AddPoint(70, 0.0);
                    opacityTransferFunction.AddPoint(255, 0.1);

                    // Create transfer mapping scalar value to color
                    vtkColorTransferFunction colorTransferFunction =
vtkColorTransferFunction.New();
                    colorTransferFunction.AddRGBPoint(0.0, 0.0, 0.0, 0.0);
                    //colorTransferFunction.AddRGBPoint(100.0, 0.0, 0.0,
1.0);
                    colorTransferFunction.AddRGBPoint(255.0, 1.0, 1.0, 1.0);

                    // The property describes how the data will look
                    vtkVolumeProperty volumeProperty =
vtkVolumeProperty.New();
                    volumeProperty.SetColor(colorTransferFunction);
                   
volumeProperty.SetScalarOpacity(opacityTransferFunction);
                    //volumeProperty.ShadeOn();
                    //volumeProperty.SetInterpolationTypeToLinear();

                    // The mapper / ray cast function know how to render the
data
                    vtkVolumeRayCastCompositeFunction compositeFunction =
vtkVolumeRayCastCompositeFunction.New();
                    vtkVolumeRayCastMapper volumeMapper =
vtkVolumeRayCastMapper.New();
                   
volumeMapper.SetVolumeRayCastFunction(compositeFunction);

                    // Link the volume render object to the byte array data
                    // volumeMapper.SetInput(myVtkImageData);
                    volumeMapper.SetInput(imageImport.GetOutput());
                    volumeMapper.Modified();

                    // The volume holds the mapper and the property and can
be used to position/orient the volume
                    vtkVolume volume = vtkVolume.New();
                    volume.SetMapper(volumeMapper);
                    volume.SetProperty(volumeProperty);
                    volume.Modified();

                    // Add volume to renderer
                    renderer.AddVolume(volume);
                    renderer.SetBackground(0, 0, 0);
                    renderer.Modified();

                    renderer.GetRenderWindow().Render();
                    gPointer.Free();
                    myByteArray = null;


                }
                catch (Exception ex) {
                    throw;
                } 


The issue is that when the program starts the first pass through the
renderer goes through and it displays as it should, the second time I get an
access violation exception. If I use similar coed for 2D however it seems to
run fine. 

Any help, tips, general advice on streaming with VTK are welcome. 

                                    Regards,
                                          Neel

Subject: [vtkusers] vtk axes change x y and z
Message-ID: <1500078798192-5743969.post@n5.nabble.com>

Hi, I am trying to hide an axis when it is perpendicular to the view plane,
i.e., very short on the screen.
It seems that xaxis, yaxis and zaxis change as the camera rotates around the
scene.  We've been trying to use the GetOrientation of the camera to know
when to hide the x y or z axis, but then the axis names keep changing, so we
get random results.

Also, I would like to use the angles calculated to rotate the alignment of
the axes labels.  When we do that, the labels get tiny, probably because
they are getting scaled to the horizontal text height.  Previous versions
posts seem to have this solution, but vtkAxesActor does not give me that
method.

axes->GetYAxisCaptionActor2D ()->GetTextActor()->SetTextScaleModeToNone(); 

Cheers, Adam

Subject: [vtkusers] How to change the cross hair shape of vtkHandleWidget
Message-ID: <35d86a13.7.15d498080a6.Coremail.tjlp@netease.com>

Hi,

I try to use vtkHandleWidget to display a point on DICOM image. If I use vtkPointHandleRepresentation2D as the reprsentation of the widget, it will display a cross hair at the point I click; if I use vtkPointHandleRepresentation3D, it will display a point.

So, how can I change the cross hair to a point if I use vtkPointHandleRepresentation2D?

Thanks
Liu Peng

Hello,

I have 4 renderers in a window, in 3 of them widgets work. However in one
of them widgets dont work. I havent done any specific changes for that
renderer.

Thanks all.

Hello,

I am new to vtk. I have a 3D polydata, I cut it using vtkClipPolydata.
Now there are some shadow kind of thing, I have called functions to turn
off shadows
as well as backface culling as off. But still shadow kind of effect remains
and the Poly data is sometimes dark due to this.

Thanks

Clipping a data set adds scalars to the data set. These scalars are
probably causing the strange coloring that you are seeing. You can tell the
mapper to ignore the scalars, and use the vtkProperty color instead:

mapper->ScalarVisibilityOff();

Hello,

sorry for late reply and thank you for the answers!
I actually managed to achieve nice smooth surface of the volume thanks to
your help! And I didn't see any significant performance change at least on
the datasets at hand.

Best regards,
Alexander

Hi everyone,
I am using vtkBooleanOperationPolyDataFilter, and it works fine except after the operation it smoothes the polydata, which I dont want. Is there a way to stop that? Or is there another library for boolean operations on polydata?

What do you mean by smooth? The lighting is smooth? I think the filter
may be adding surface normals, in which case any actor for the data
will turn on Gouraud shading (or maybe Phong) by default, which will
make your surface look smooth. You can turn off smooth lighting as
shown in this example:

Dear Cory,
Thanks for the reply, I set the actors property to? SetInterpolationToFlat(); as you said, but the result is the same I put a picture before and after boolean operation here. Any suggestion? Are you familier with any other library? Current boolean operation takes about 150 seconds on my system, do you think this is normal?

There shouldn't be any geometry smoothing going on in this filter. Can you
verify that the geometry has changed in the smoothed version?

This is speculation, but one possibility is that the surface normals in
your original surface come from a gradient computation in the volume from
which the surface was extracted and noise in the volume result in the bumpy
appearance. You can check this by applying the vtkPolyDataNormals filter to
your original surface and looking at the result.

HTH,
Cory

Dear Cory,
As I applied vtkPolyDataNormals to the polydata before the boolean operation I got the smoothed object, so you were right. But I dont understand exactly what is happening here? Since the geometry dimentions are very important for my application, Can I have the noisy version? Is there any way I do not get it smoothed?
Thanks,

What I think you are seeing with the rough surface is surface normals
generated from an image volume. I am assuming a lot here, so please correct
me if I am wrong. It looks like you have a geometry of a bone extracted
from a CT scan. The extraction algorithm was probably a variant of marching
cubes or a similar algorithm. The surface normals estimated from the
surface extraction algorithm were probably computed from the intensity
gradient of the CT scan. This is a reasonable approach, but noise in the CT
scan will affect the gradient calculation and may perturb the surface
normals in the geometry a little. When this happens, you can get a rough
appearing surface from the surface lighting calculation. Google "bump
mapping" for how this can be used for a nice graphics effect - I think
roughly the same thing is happening with your original data.

When you use vtkPolyDataNormals, the normals are computed from the surface
data, which was smooth to begin with. Hence, the normals are not perturbed,
so you don't get a bumpy appearance.

In any case, the measurements you want to take are not dependent on the
surface normals. As long as the points on the surface are not smooth, which
they should not be, your measurement procedure should be fine.

To convince yourself the geometry is the same, you can display both the
original "bumpy" surface and the smoothed surface at the same time with
different colors. You should see just one surface or the other, probably
the one you added to the vtkRenderer last. If the geometry is different,
you will see some of one surface color and some of the other depending on
which geometry is closer to the camera. I suspect you will see just one
surface.

Cory

Dear Cory,
All you said was exactly what I have done. I tested your method to check the data and I could see only one of the objects. So If I understand right, during the boolean operation the vtkPolyDataNormals are recalculated and that is the reason the polydata is shown smoothed. Is there a way not to let boolean recalculate it? Or more generally is there a way to keep the bumps. That kind of is the norm in the medical field and some doctors might not feel very good about the smooth data. 
Thanks.

This is speculation, but one possibility is that the surface normals in your original surface come from a gradient computation in the volume from which the surface was extracted and noise in the volume result in the bumpy appearance. You can check this by applying the vtkPolyDataNormals filter to your original surface and looking at the result.

Hi,

I am using VTK version 7.1.
Set up:
I have one render window, 4 tiles which correspond to 4 renderers, each of
them have different actors.
One renderer which has Actor2D (image) doesnt respond to any widgets.
I am using slider widget, button widget.
But they work on other renderers, there is no specific change that was done
to this renderer alone.

Thanks,

Thanks,
if  I turn off scalars then I see only white color, by the way even after
that I see the shadow effects, how can I turn off the shadows in the scene
completely.
I think the problem is with respect to shadows.

Thanks again.

I know that the button widget has issues when using with multiple
viewports. Its possible that the slider widget has similar issues.
I'll look into it. Hopefully, we?ll have a fix soon.

Thanks,

If it isn't the scalars, then it is probably the normals.  If the data has
bad normals, then lighting of the data will be incorrect.

You can try generating new normals for the data with vtkPolyDataNormals.
Make sure that you read the documentation for this class, it has lots of
options.

Message-ID: <1500329931056-5743997.post@n5.nabble.com>

I am trying to measure the performance of the VTK application. I am trying
find whether my application is using graphic card or not. Can anyone let me
know how do I check this.

I had the NVidia graphic card installed on my system and all the drivers are
updated.

Thanks for you time

Update: paper submission due date extended to 15 Aug 2017 23:59 AoE

ISAV 2017: In Situ Infrastructures for Enabling Extreme-Scale Analysis and Visualization

In cooperation with SIGHPC and held in conjunction with SC17: The International Conference on High Performance Computing, Networking, Storage and Analysis, Denver, Colorado, U.S.A.

            ISAV 2017 - http://vis.lbl.gov/Events/ISAV-2017/

         Full-day 9:00 AM - 5:30 PM Sunday November 12th, 2017

Workshop Theme

The considerable interest in the HPC community regarding in situ analysis and visualization is  due to several factors. First is an I/O cost savings, where data is analyzed/visualized while  being generated, without first storing to a file system. Second is the potential for increased  accuracy, where fine temporal sampling of transient analysis might expose some complex behavior missed in coarse temporal sampling. Third is the ability to use all available resources, CPUs and accelerators, in the computation of analysis products.

The workshop brings together researchers, developers and practitioners from industry, academia, and government laboratories developing, applying, and deploying in situ methods in extreme-scale, high performance computing. The goal is to present research findings, lessons learned, and insights related to developing and applying in situ methods and infrastructure across a range of science and engineering applications in HPC environments; to discuss topics like opportunities presented by new architectures, existing infrastructure needs, requirements, and gaps, and experiences to foster and enable in situ analysis and visualization; to serve as a "center of gravity" for researchers, practitioners, and users/consumers of in situ methods and infrastructure in the HPC space.

Participation/Call for Papers and Oral Presentations

We invite two types of submissions to ISAV 2017: (1) short, 4-page papers that present research results, that identify opportunities or challenges, and that present case studies/best practices for in situ methods/infrastructure in the areas of data management, analysis and visualization; (2) lightning presentation submission, consisting of a 1- or 2-page submission, for a brief oral presentation at the workshop. 
Short papers will appear in the workshop proceedings and will be invited to give an oral presentation of 15 to 20 minutes; lightning round submissions that are invited to present at the workshop will have author names and titles included as part of the proceedings. Submissions of both types are welcome that fall within one or more areas of interest, as follows:

Areas of interest for ISAV, include, but are not limited to:

    In situ infrastructures

       * Current Systems: production quality, research prototypes
       * Opportunities
       * Gaps

    System resources, hardware, and emerging architectures

       * Enabling Hardware
       * Hardware and architectures that provide opportunities for in situ processing, such as burst buffers, staging computations on I/O nodes, sharing cores within a node for both simulation and in situ processing

    Methods/algorithms/applications/Case studies

       * Best practices
       * Analysis: feature detection, statistical methods, temporal methods, geometric methods
       * Visualization: information visualization, scientific visualization, time-varying methods
       * Data reduction/compression
       * Examples/case studies of solving a specific science challenge with in situ methods/infrastructure.

    Simulation

       * Integration: data modeling, software-engineering
       * Resilience: error detection, fault recovery
       * Workflows for supporting complex in situ processing pipelines

    Requirements

       * Preserve important elements
       * Significantly reduce the data size
       * Flexibility for post-processing exploration


Review Process

All submissions will undergo a peer-review process consisting of three reviews by experts in the field, and evaluated according to relevance to the workshop theme, technical soundness, creativity, originality, and impactfulness of method/results. Lightning round submissions will be evaluated primarily for relevance to the workshop.

Submission Process

Authors are invited to submit papers of at most 4 pages in PDF format, excluding references, and lightning presentations of at most 2 pages in PDF format, excluding references. Papers must be submitted in PDF format (readable by Adobe Acrobat Reader 5.0 and higher) and formatted for 8.5" x 11" (U.S. Letter). Submissions are required in the ACM format (http://www.acm.org/sigs/publications/proceedings-templates) using the sample-sigconf template and submitted via EasyChair (https://easychair.org/conferences/?conf=isav17). No changes to the margins, spacing, or font sizes as specified by the style file are allowed.

Papers must be self-contained and provide the technical substance required for the program committee to evaluate their contributions. Submitted papers must be original work that has not appeared in and is not under consideration for another conference or a journal. See the ACM Prior Publication Policy for more details (http://www.acm.org/publications/policies/). Papers can be submitted at https://easychair.org/conferences/?conf=isav17.

Publication in proceedings, presentation at the workshop

All paper submissions that receive favorable reviews will be included as part of the workshop proceedings, which will be published through SIGHPC along with other SC17 workshop proceedings in the ACM Digital Library and IEEE Xplore. Lightning round submissions will not be included as part of the proceedings.

Subject to the constraints of workshop length, some subset of the accepted publications will be invited to give a brief oral presentation at the workshop. The exact number of such presentations and their length will be determined after the review process has been completed.

Subject: [vtkusers] How to trigger an event programmatically instead of
 mouse click or move?
Message-ID: <5f2ba86f.5.15d54a87c96.Coremail.tjlp@netease.com>

Hi,

I have 2 RenderWindows for DICOM axial plane and 3D model respectively. I want to measure distance on these 2 windows at the same time with vtkDistanceWidget. So, is possible that if an event, such as PlacePointEvent, is triggered by mouse on axial plane RenderWindow, the same event with the same world position values is triggered programmatically on the 3D model RenderWindow?

Thanks
Liu Peng

Subject: [vtkusers] Delayloading VTK
Message-ID: <1500373976551-5744000.post@n5.nabble.com>

Hi everyone,

I am trying to delay load some vtk DLLs in my application. I want to achieve
to set different DLL directory for opengl32.dll to switch to a software
renderer. Despite declaring the dlls with /DELAYLOAD:<module> some DLLs are
instantly loaded at startup of the application. I traced it down and it
seems to be related with VTK_MODULE_INIT. This seems to initialize some
stuff right at startup and therefore loading some vtk DLLS.

Is there anyway to delay the initialization of the VTK modules, so that the
delayloading actually works?

Best Regards

Klaus

After further fidling I found a solution that seems to work for me.
I simply recompiled VTK with /DELAYLOAD:opengl32.dll and it seems to work
fine. Lets see what further testing brings up.

Hmm, now I wonder if the boolean operations filter is simply removing the
normals filter. The code has changed from the original, which did preserve
normals. It looks like the current code should preserve normals as well,
but I'm not 100% sure if that is the case.

In the output of the boolean operation filter, could you check that there
is a normals array in the pointdata?

vtkDataArray* normals = output->GetPointData()->GetNormals();

If "normals" is NULL, then the normals are not being copied to the output.

Thanks,
Cory

Dear Cory,
!normals returns true, so as you said there is no normal array. Is there a way to copy that before the operation and apply it afterwards? But I think that wont work because part of the data is changed in the boolean operation. So how can we keep the normals?

Thanks,

In any case, the measurements you want to take are not dependent on the surface normals. As long as the points on the surface are not smooth, which they should not be, your measurement procedure should be fine.
To convince yourself the geometry is the same, you can display both the original "bumpy" surface and the smoothed surface at the same time with different colors. You should see just one surface or the other, probably the one you added to the vtkRenderer last. If the geometry is different, you will see some of one surface color and some of the other depending on which geometry is closer to the camera. I suspect you will see just one surface.

Dear Cory,
As I applied vtkPolyDataNormals to the polydata before the boolean operation I got the smoothed object, so you were right. But I dont understand exactly what is happening here? Since the geometry dimentions are very important for my application, Can I have the noisy version? Is there any way I do not get it smoothed?
Thanks,

This is speculation, but one possibility is that the surface normals in your original surface come from a gradient computation in the volume from which the surface was extracted and noise in the volume result in the bumpy appearance. You can check this by applying the vtkPolyDataNormals filter to your original surface and looking at the result.

Dear Cory,
Thanks for the reply, I set the actors property to? SetInterpolationToFlat(); as you said, but the result is the same I put a picture before and after boolean operation here. Any suggestion? Are you familier with any other library? Current boolean operation takes about 150 seconds on my system, do you think this is normal?

What do you mean by smooth? The lighting is smooth? I think the filter
may be adding surface normals, in which case any actor for the data
will turn on Gouraud shading (or maybe Phong) by default, which will
make your surface look smooth. You can turn off smooth lighting as
shown in this example:

Okay, let's try one more thing. Does

vtkDataArray* normals = output->GetPointData()->GetArray("Normals");

return NULL? Perhaps the normals array is being copied but not being set as
the active normals.

Thanks,
Cory

You'll have to cast your render window to vtkOpenGLRenderWindow.
If w is your render window you have to:

vtkOpenGLExtensionManager *extensions = w->GetExtensionManager();
std::cout << extensions->GetDriverGLVendor() << std::endl
              << extensions->GetDriverGLVersion() << std::endl
              << extensions->GetDriverGLRenderer() << std::endl;

You might try

cout << yourRenderWindow->ReportCapabilities();

or something like that

Hi Everybody,

The VTK team is always looking to attract new developers and improve
the experience of developing VTK.

To further that, we are putting out an anonymous survey to collect
data on people's thoughts about the current software development
process for VTK.  We would love to hear all your rants ( or raves ) on
the development process. We will gather the results after August 1'st.

https://goo.gl/forms/WlqyiF0sBTZT7klJ3

Thank you for your inputs.

With this function "ReportCapabilities()" I was able to find whether my
application is using gpu or not.

I was wondering if there is any module in VTK for profiling VTK.

Thanks for your time

Message-ID: <1500440051624-5744009.post@n5.nabble.com>

I have a vtkImageData and a vtkImageViewer2, I use SetInputData() to set
vtkImageData rendered by vtkImageViewer2. However, I have changed the pixel
value of vtkImageData by changing the scalar pointer. 

Now I cannot update the viewer to see the new image, how can I do this?

I have learned some past posts, they have metioned Update() method and
Modified() method, but they didn't work for me.

Dear Cory,
It is still Null. Can we recalculate normals on the output of boolean operation?

Okay, let's try one more thing. Does
vtkDataArray* normals = output->GetPointData()->GetArray("Normals");

return NULL? Perhaps the normals array is being copied but not being set as the active normals.
Thanks,Cory

Dear Cory,
!normals returns true, so as you said there is no normal array. Is there a way to copy that before the operation and apply it afterwards? But I think that wont work because part of the data is changed in the boolean operation. So how can we keep the normals?

Thanks,

Hmm, now I wonder if the boolean operations filter is simply removing the normals filter. The code has changed from the original, which did preserve normals. It looks like the current code should preserve normals as well, but I'm not 100% sure if that is the case.
In the output of the boolean operation filter, could you check that there is a normals array in the pointdata?
vtkDataArray* normals = output->GetPointData()-> GetNormals();
If "normals" is NULL, then the normals are not being copied to the output.
Thanks,Cory

Dear Cory,
All you said was exactly what I have done. I tested your method to check the data and I could see only one of the objects. So If I understand right, during the boolean operation the vtkPolyDataNormals are recalculated and that is the reason the polydata is shown smoothed. Is there a way not to let boolean recalculate it? Or more generally is there a way to keep the bumps. That kind of is the norm in the medical field and some doctors might not feel very good about the smooth data. 
Thanks.

What I think you are seeing with the rough surface is surface normals generated from an image volume. I am assuming a lot here, so please correct me if I am wrong. It looks like you have a geometry of a bone extracted from a CT scan. The extraction algorithm was probably a variant of marching cubes or a similar algorithm. The surface normals estimated from the surface extraction algorithm were probably computed from the intensity gradient of the CT scan. This is a reasonable approach, but noise in the CT scan will affect the gradient calculation and may perturb the surface normals in the geometry a little. When this happens, you can get a rough appearing surface from the surface lighting calculation. Google "bump mapping" for how this can be used for a nice graphics effect - I think roughly the same thing is happening with your original data.
When you use vtkPolyDataNormals, the normals are computed from the surface data, which was smooth to begin with. Hence, the normals are not perturbed, so you don't get a bumpy appearance.
In any case, the measurements you want to take are not dependent on the surface normals. As long as the points on the surface are not smooth, which they should not be, your measurement procedure should be fine.
To convince yourself the geometry is the same, you can display both the original "bumpy" surface and the smoothed surface at the same time with different colors. You should see just one surface or the other, probably the one you added to the vtkRenderer last. If the geometry is different, you will see some of one surface color and some of the other depending on which geometry is closer to the camera. I suspect you will see just one surface.

Dear Cory,
As I applied vtkPolyDataNormals to the polydata before the boolean operation I got the smoothed object, so you were right. But I dont understand exactly what is happening here? Since the geometry dimentions are very important for my application, Can I have the noisy version? Is there any way I do not get it smoothed?
Thanks,

This is speculation, but one possibility is that the surface normals in your original surface come from a gradient computation in the volume from which the surface was extracted and noise in the volume result in the bumpy appearance. You can check this by applying the vtkPolyDataNormals filter to your original surface and looking at the result.

Dear Cory,
Thanks for the reply, I set the actors property to? SetInterpolationToFlat(); as you said, but the result is the same I put a picture before and after boolean operation here. Any suggestion? Are you familier with any other library? Current boolean operation takes about 150 seconds on my system, do you think this is normal?

What do you mean by smooth? The lighting is smooth? I think the filter
may be adding surface normals, in which case any actor for the data
will turn on Gouraud shading (or maybe Phong) by default, which will
make your surface look smooth. You can turn off smooth lighting as
shown in this example:

Hi Summer,

I had the same problem, and the solution that worked for me was:

1. Use the modified function, for example I was updating the pixel values of
my pointer vtkSmartPointer<vtkImageData> vtk_Im, and after
vtk_Im->Modified(). 

2. Sure, with the Modified() function your vtkImageViewer2 isn't updated.
So, you have to call the method Render() of your pointer vtkImageViewer2
every time after you update your vtkImageData pointer.

I hope this works for you.

Hello, I'm working at the moment with VTK 7.1.1 on Java 8, using AWT. VTK
works fine on Linux and Windows but not on macOS. That is the reason why I
would like to know if using JOGL could solve this problem. I would also like
to know if JOGL is the new standard for VTK in Java, and if AWT will still
be maintained.

Subject: [vtkusers] Using vtkExternalOpenGLCamera
Message-ID: <1500472740832-5744015.post@n5.nabble.com>

Hi everyone!

I'm building a program that uses the externalVTKWidget to volume render an
object in an OpenGL context. Right now, I'm calling 

*ren->GetActiveCamera();
*

(where ren is a vtkExternalOpenGLRenderWindow instance) in my render
function so I can control the position and focal point of the camera.
However, I'm unable to get the camera to actually have any effect on the
scene. The documentation for vtkExternalOpenGLCamera is rather slim, and I
can't find any similar examples, so I am a bit stuck on this issue. 

Does anyone have any insight into how I could approach this problem? Thanks
in advance!

Elaine

Subject: [vtkusers] QVTK Widget odd behavior on Ubuntu 16.10 and NVidia GPU:
Message-ID: <1500475655836-5744016.post@n5.nabble.com>

Hello all,

I have been working making an application cross platform between MacOS and
Linux Ubuntu. This piece of software is built around Qt 5.9.1 and VTK 8 for
the GUI side of things.

After a lot of fiddling, I'm pleased to say I have no issue at all on MacOS.
Here's a link to the Github Wiki of the project, with an illustration of
what it looks like as of today when operating nominally
(https://github.com/bbercovici/SBGAT/wiki)

Unfortunately, I am not quite there yet on Linux/Ubuntu. Specifically, the
QVTKWidget at the center of the QMainWindow constituting the GUI acts weird.

Here's what's happening when I am running SBGAT on Linux:

- Upon launch, the QVTKWidget 'separates' from the QMainWindow, so that I am
left with two windows instead of one
- The QMainWindow window works fine. All the buttons are responsive.
- The QVTKWidget is not responsive. No interaction appears to take place
between the mouse cursor upong clicking and the camera orientation.
- There is a strange "ghosting" effect with portions of the QVTKWidget that
do not get redrawn properly, but show neighboring desktop elements or
windows when moved around
- When loading in an .obj file using the QMainWindow actions, it gets
displayed on the QVTKWidget (so there is "some" rendering going on, although
no interaction is possible).

My desktop has a NVIDIA 980 GTX GPU, and I am using the latest NVidia
drivers I could find on apt-get (nvidia 384 I believe). 

I believe a more detailed error message is sometimes spitted out by SBGAT
upon leaving, I will copy/paste it here later today.

Is there anyone who was able to make QVTKWidgets work on a similar platform?

Thanks,
Ben

I recommend using the new QVTKOpenGLWidget with Qt 5 instead of QVTKWidget (

Utkarsh, 
thanks for the suggestion.

I'm trying to have this working on my Mac first.

I have replaced the QVTKWidget by a QVTKOpenGLWidget, and set its render
window to a vtkGenericOpenGLRenderWindow.

*
vtkSmartPointer< vtkGenericOpenGLRenderWindow> render_window =
vtkSmartPointer< vtkGenericOpenGLRenderWindow>::New();
this -> qvtkWidget -> SetRenderWindow(render_window);
this -> qvtkWidget -> GetRenderWindow() -> AddRenderer(this -> renderer);
*

Unfortunately it segfaults after returning the following error message:
*
Warning: In
/Users/bbercovici/VTK/VTK_source/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx,
line 835
vtkGenericOpenGLRenderWindow (0x7f97260f8e00): VTK is designed to work with
OpenGL version 3.2 but it appears it has been given a context that does not
support 3.2. VTK will run in a compatibility mode designed to work with
earlier versions of OpenGL but some features may not work.

I recompiled VTK beforehand with the -DVTK_RENDERING_BACKEND:STRING=OpenGL2
flag. Is OpenGL3 a thing?

No,  VTK_RENDERING_BACKEND:STRING=OpenGL2 is indeed what you want.

Also make sure before you create the QApp in your main, you're calling
`QSurfaceFormat::setDefaultFormat(QVTKOpenGLWidget::defaultFormat())`. Is
that the case?

`QSurfaceFormat::setDefaultFormat(QVTKOpenGLWidget::defaultFormat())` was the

Hi, I'm using vtkImageBlend to blend two?vtkImageMapToColors. Right now if I change the opacity map of the first vtkImageMapToColors (via lookup table), it adjusts the entire alpha of the output (so for example hiding the first one hides both of them). Is there a way to prevent vtkImageBlend from assigning the opacity of the first element to the output? I've tried using the "compound" blending mode in case that would help, but the screen is blank then. Any help would be great!
This is a simplified version of the code I'm using:
vtkSmartPointer<vtkImageMapToColors> imapper1 = vtkSmartPointer<vtkImageMapToColors>::New();imapper1->SetLookupTable(lut1);imapper1->PassAlphaToOutputOn();imapper1->SetInputData(image1);imapper1->Update();
vtkSmartPointer<vtkImageMapToColors> imapper2 = vtkSmartPointer<vtkImageMapToColors>::New();imapper2->SetLookupTable(lut2);imapper2->PassAlphaToOutputOn();imapper2->SetInputData(image2);imapper2->Update();
vtkSmartPointer<vtkImageBlend> blend = vtkSmartPointer<vtkImageBlend>::New();blend->AddInputConnection(imapper1->GetOutputPort());blend->SetOpacity(0, 1.0);blend->AddInputConnection(imapper2->GetOutputPort());blend->SetOpacity(1, 1.0);
// If I now render and adjust lut1, it affects the output of blend so the imapper2 image gets affected

Did you follow the instructions in the docs for QVTKOpenGLWidget [1] ?
Specifically, you need to set the default QSurfaceFormat to an
appropriate one with

    QSurfaceFormat::setDefaultFormat(QVTKOpenGLWidget::defaultFormat());

Two options I know of

1) build your executable against Mesa so it will run everywhere

2) gracefully test if the hardware supports OpenGL2 and gracefully exit if
not. In current VTK you can do this but I think in 7.1 it may not work.
Basically call renWin->GetSupportsOpenGL() and handle accordingly.

To clarify on Utkarsh's answer, "OpenGL2" is just the name of the backend
(as the second OpenGL backend to VTK).  The required version of OpenGL to
use the "OpenGL2" backend is OpenGL 3.2.

Message-ID: <16c05f52-6331-6d91-f9e6-6d7a17fd0590@calculquebec.ca>

Hi,
I am trying to compile VTK 8.0. I am passing the following flags to cmake :
cmake . - 
DCMAKE_INSTALL_PREFIX=/home/mboisson/.local/easybuild/software/2017/avx2/MPI/intel2016.4/openmpi2.1/vtk/8.0.0 
-DCMAKE_C_COMPILER='icc' -DCMAKE_Fortran_FLAGS='-O2 -xCore-AVX2 -ftz 
-fp-speculation=safe -fp-model source' -DCMAKE_CXX_FLAGS='-O2 
-xCore-AVX2 -ftz -fp-speculation=safe -fp-model source' 
-DCMAKE_CXX_COMPILER='icpc' -DCMAKE_Fortran_COMPILER='ifort' 
-DCMAKE_C_FLAGS='-O2 -xCore-AVX2 -ftz -fp-speculation=safe -fp-model 
source' -DCMAKE_VERBOSE_MAKEFILE=ON 
-DPYTHON_LIBRARY=$EBROOTPYTHON/lib/libpython2.7.so 
-DPYTHON_INCLUDE_DIR=$EBROOTPYTHON/include/python2.7


Python is found, but the bindings are not created.

Below is a grep of "python" from the CMakeCache.txt.

Anyone got an idea on how to fix this ? Thanks

Is thr any way to find out OpenGL version in VTK .
 So that system which supports OpenGL 2.0 can make use of VTK 7.0 OpenGL
2.0 as Rendering backed.

System which won't support OpenGL 2.0 can make use of OpenGL as Rendering
backend.

Unfortunately, the program crashes on my Ubuntu platform upon rendering. That
is, it segfaults at

*
this -> qvtkWidget -> GetRenderWindow() -> Render();
*

Where the render window is an instance of vtkGenericOpenGLRenderWindow.

Any thoughts?

Subject: [vtkusers] Setting camera to view the rendered slice
Message-ID: <VI1PR0902MB2046174C36947BEB86E448CD83A70@VI1PR0902MB2046.eurprd09.prod.outlook.com>

Dear VTK users,


I have an issue related to the Setting camera to view the rendered slice to the whole viewport.

For the axial plane, the formula which I am using is the following:


float yd = (image_vtk->GetExtent()[3] - image_vtk->GetExtent()[2] + 1)*image_vtk->GetSpacing()[1];

      float d = camera->GetDistance();
      camera->SetParallelScale(0.5f*yd);



I would like to change it in order to get the Coronal plane.

Thank you in advance.


Best regards,


Abdelkhalek Bakkari

Just some clarification: The current rendering backend in VTK is
called "OpenGL2", because it's the second version of the OpenGL
backend. It requires OpenGL 3.2.

The old backend is called just "OpenGL". I'm not sure which version of
OpenGL it requires.

It's easy to confuse the name of the backend "OpenGL2" and think that
the 2 means OpenGL version 2. But it's just a name. Perhaps it would
have been better to call it OpenGLNG or something for that reason.

It's not possible to build a VTK that has both the OpenGL and OpenGL2
backend built, and I'm not sure if it would be possible to deliver an
application with two versions of VTK (one with OpenGL2 and one with
OpenGL) and choose which one to use at runtime. Maybe.. but it would
be rather complicated.

Like Ken said, if you want something that runs everywhere, I think the
only option is to build against Mesa.

All:

After multiple attempts, I have not been able to compile VTK with OpenVR. With the project directory set to the OpenVR directory, I receive the following output. This is expected because vtkObjectFactory is part of the main project.


Found OpenVR: C:/Users/Geoffrey/vcpkg/installed/x64-windows/include 
CMake Error at CMakeLists.txt:42 (include):
include could not find load file:

vtkObjectFactory
CMake Error at CMakeLists.txt:43 (vtk_add_override):
Unknown CMake command "vtk_add_override".
CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as

cmake_minimum_required(VERSION 3.9)

should be added at the top of the file. The version specified may be lower
if you wish to support older CMake versions for this project. For more
information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.
Configuring incomplete, errors occurred!
See also "C:/Users/Geoffrey/workspace/VTK/Rendering/OpenVR/build/CMakeFiles/CMakeOutput.log".
See also "C:/Users/Geoffrey/workspace/VTK/Rendering/OpenVR/build/CMakeFiles/CMakeError.log".


However, what is not expected is the following when configuring the main project. There is no OpenVR folder in the build directory and no explanation of why. Yes, I have SDL2 and OpenVR from vcpkg.

But you can build two VTK different ?versions one ?with OpenGL and second with OpenGL2 ?and to use platform supported on current machine.?

Just some clarification: The current rendering backend in VTK is
called "OpenGL2", because it's the second version of the OpenGL
backend. It requires OpenGL 3.2.

The old backend is called just "OpenGL". I'm not sure which version of
OpenGL it requires.

It's easy to confuse the name of the backend "OpenGL2" and think that
the 2 means OpenGL version 2. But it's just a name. Perhaps it would
have been better to call it OpenGLNG or something for that reason.

It's not possible to build a VTK that has both the OpenGL and OpenGL2
backend built, and I'm not sure if it would be possible to deliver an
application with two versions of VTK (one with OpenGL2 and one with
OpenGL) and choose which one to use at runtime. Maybe.. but it would
be rather complicated.

Like Ken said, if you want something that runs everywhere, I think the
only option is to build against Mesa.

 Thanks. That worked.
  

  
Is this something that changed with version 8.0 ? I don't see this option in my install notes for version 7.x and the python bindings were installed.

That's strange, because this option has always been necessary for enabling
the python wrappers.

Hi,
I have a small Qt+VTK project here for my students:
https://bitbucket.org/spir_robert/qt-vtk-widgets
Master branch has QVTKOpenGLWidget and QVTKWidget branch has QVTKWidget.
Both of them works fine in linux, windows and MacOS with Qt 5.9 and VTK 8.

Robert

GPU:

Unfortunately, the program crashes on my Ubuntu platform upon rendering.
That is, it segfaults at

*
this -> qvtkWidget -> GetRenderWindow() -> Render();
*

Where the render window is an instance of vtkGenericOpenGLRenderWindow.

Any thoughts?

Okay, let's try one more thing. Does

return NULL? Perhaps the normals array is being copied but not being set as the active normals.

Dear Cory,
!normals returns true, so as you said there is no normal array. Is there a way to copy that before the operation and apply it afterwards? But I think that wont work because part of the data is changed in the boolean operation. So how can we keep the normals?

Thanks,

Hmm, now I wonder if the boolean operations filter is simply removing the normals filter. The code has changed from the original, which did preserve normals. It looks like the current code should preserve normals as well, but I'm not 100% sure if that is the case.
In the output of the boolean operation filter, could you check that there is a normals array in the pointdata?
vtkDataArray* normals = output->GetPointData()-> GetNormals();
If "normals" is NULL, then the normals are not being copied to the output.
Thanks,Cory

Dear Cory,
All you said was exactly what I have done. I tested your method to check the data and I could see only one of the objects. So If I understand right, during the boolean operation the vtkPolyDataNormals are recalculated and that is the reason the polydata is shown smoothed. Is there a way not to let boolean recalculate it? Or more generally is there a way to keep the bumps. That kind of is the norm in the medical field and some doctors might not feel very good about the smooth data. 
Thanks.

What I think you are seeing with the rough surface is surface normals generated from an image volume. I am assuming a lot here, so please correct me if I am wrong. It looks like you have a geometry of a bone extracted from a CT scan. The extraction algorithm was probably a variant of marching cubes or a similar algorithm. The surface normals estimated from the surface extraction algorithm were probably computed from the intensity gradient of the CT scan. This is a reasonable approach, but noise in the CT scan will affect the gradient calculation and may perturb the surface normals in the geometry a little. When this happens, you can get a rough appearing surface from the surface lighting calculation. Google "bump mapping" for how this can be used for a nice graphics effect - I think roughly the same thing is happening with your original data.
When you use vtkPolyDataNormals, the normals are computed from the surface data, which was smooth to begin with. Hence, the normals are not perturbed, so you don't get a bumpy appearance.
In any case, the measurements you want to take are not dependent on the surface normals. As long as the points on the surface are not smooth, which they should not be, your measurement procedure should be fine.
To convince yourself the geometry is the same, you can display both the original "bumpy" surface and the smoothed surface at the same time with different colors. You should see just one surface or the other, probably the one you added to the vtkRenderer last. If the geometry is different, you will see some of one surface color and some of the other depending on which geometry is closer to the camera. I suspect you will see just one surface.

Dear Cory,
As I applied vtkPolyDataNormals to the polydata before the boolean operation I got the smoothed object, so you were right. But I dont understand exactly what is happening here? Since the geometry dimentions are very important for my application, Can I have the noisy version? Is there any way I do not get it smoothed?
Thanks,

This is speculation, but one possibility is that the surface normals in your original surface come from a gradient computation in the volume from which the surface was extracted and noise in the volume result in the bumpy appearance. You can check this by applying the vtkPolyDataNormals filter to your original surface and looking at the result.

Dear Cory,
Thanks for the reply, I set the actors property to? SetInterpolationToFlat(); as you said, but the result is the same I put a picture before and after boolean operation here. Any suggestion? Are you familier with any other library? Current boolean operation takes about 150 seconds on my system, do you think this is normal?

What do you mean by smooth? The lighting is smooth? I think the filter
may be adding surface normals, in which case any actor for the data
will turn on Gouraud shading (or maybe Phong) by default, which will
make your surface look smooth. You can turn off smooth lighting as
shown in this example:

Hi Mike,

There is no way to change this behavior for vtkImageBlend.  One solution is
to use a dummy image as input 0 (same dimensions as your first image, but
with RGBA set to 0,0,0,1 for all pixels), and then add your two images as
inputs 1 and 2.

You should be able to use vtkResampleWithDataSet [1] to sample the Normals
array from the input bone data to the boolean operation output. You will
get invalid normals for the indented region, though.

That's all I've got for suggestions other than someone figuring out in the
boolean operations code why the normals aren't getting copied.

Thanks,
Cory

Thank you so much Cory for the time and effort. Can I submit this as a bug, or do you know to whom should I ask this directly?

You should be able to use vtkResampleWithDataSet [1] to sample the Normals array from the input bone data to the boolean operation output. You will get invalid normals for the indented region, though.
That's all I've got for suggestions other than someone figuring out in the boolean operations code why the normals aren't getting copied.

Dear Cory,
!normals returns true, so as you said there is no normal array. Is there a way to copy that before the operation and apply it afterwards? But I think that wont work because part of the data is changed in the boolean operation. So how can we keep the normals?

Thanks,

Hmm, now I wonder if the boolean operations filter is simply removing the normals filter. The code has changed from the original, which did preserve normals. It looks like the current code should preserve normals as well, but I'm not 100% sure if that is the case.
In the output of the boolean operation filter, could you check that there is a normals array in the pointdata?
vtkDataArray* normals = output->GetPointData()-> GetNormals();
If "normals" is NULL, then the normals are not being copied to the output.
Thanks,Cory

Dear Cory,
All you said was exactly what I have done. I tested your method to check the data and I could see only one of the objects. So If I understand right, during the boolean operation the vtkPolyDataNormals are recalculated and that is the reason the polydata is shown smoothed. Is there a way not to let boolean recalculate it? Or more generally is there a way to keep the bumps. That kind of is the norm in the medical field and some doctors might not feel very good about the smooth data. 
Thanks.

What I think you are seeing with the rough surface is surface normals generated from an image volume. I am assuming a lot here, so please correct me if I am wrong. It looks like you have a geometry of a bone extracted from a CT scan. The extraction algorithm was probably a variant of marching cubes or a similar algorithm. The surface normals estimated from the surface extraction algorithm were probably computed from the intensity gradient of the CT scan. This is a reasonable approach, but noise in the CT scan will affect the gradient calculation and may perturb the surface normals in the geometry a little. When this happens, you can get a rough appearing surface from the surface lighting calculation. Google "bump mapping" for how this can be used for a nice graphics effect - I think roughly the same thing is happening with your original data.
When you use vtkPolyDataNormals, the normals are computed from the surface data, which was smooth to begin with. Hence, the normals are not perturbed, so you don't get a bumpy appearance.
In any case, the measurements you want to take are not dependent on the surface normals. As long as the points on the surface are not smooth, which they should not be, your measurement procedure should be fine.
To convince yourself the geometry is the same, you can display both the original "bumpy" surface and the smoothed surface at the same time with different colors. You should see just one surface or the other, probably the one you added to the vtkRenderer last. If the geometry is different, you will see some of one surface color and some of the other depending on which geometry is closer to the camera. I suspect you will see just one surface.

Dear Cory,
As I applied vtkPolyDataNormals to the polydata before the boolean operation I got the smoothed object, so you were right. But I dont understand exactly what is happening here? Since the geometry dimentions are very important for my application, Can I have the noisy version? Is there any way I do not get it smoothed?
Thanks,

There shouldn't be any geometry smoothing going on in this filter. Can you verify that the geometry has changed in the smoothed version?
This is speculation, but one possibility is that the surface normals in your original surface come from a gradient computation in the volume from which the surface was extracted and noise in the volume result in the bumpy appearance. You can check this by applying the vtkPolyDataNormals filter to your original surface and looking at the result.

Dear Cory,
Thanks for the reply, I set the actors property to? SetInterpolationToFlat(); as you said, but the result is the same I put a picture before and after boolean operation here. Any suggestion? Are you familier with any other library? Current boolean operation takes about 150 seconds on my system, do you think this is normal?

What do you mean by smooth? The lighting is smooth? I think the filter
may be adding surface normals, in which case any actor for the data
will turn on Gouraud shading (or maybe Phong) by default, which will
make your surface look smooth. You can turn off smooth lighting as
shown in this example:

Sure, feel free to submit a bug (https://gitlab.kitware.com/vtk/vtk). If
you can include a self-contained code sample with either VTK source objects
(e.g., vtkSphereSource) or small data files, that would greatly aid whoever
takes on the bug in the future.

Not really which is why there is OpenGL2. The old OpenGL backend supports
all the way back to OpenGL 1.0. The problem is that most modern rendering
techniques will not work on OpenGL 1.0.

Keeping OpenGL (or extending it) was resulting more and more in a situation
where we had to say things like "Well LIC works, but only on these graphics
cards" As more modern features were added it was getting to the point where
what worked on your computer was in no way assured to work on another
computer.

OpenGL2 moves the baseline to OpenGL version 3.2 which is about six or
seven years old but has a lot of features that support modern graphics
programming. Now we can say if it runs at all, every feature should work.
This creates a different problem which we have been working on to make sure
all platforms have an option to support OpenGL 3.2. For OSX it is easy as
Apple already guarantees OpenGL 3.2 on any OS from the past many years. For
linux and windows it is trickier. Often updating your driver or Mesa
version solves the issue. Sometimes not.

Mesa will work on both platforms but currently we (and the operating
systems) do not have a good approach to try for hardware OpenGL 3.2 and if
not available, fall back to Mesa. It is something we think about regularly
though and we have some hopes that in the near future a more general
virtual dispatch mechanism will be implemented to solve this issue.

Thanks
Ken

"Yes, I have SDL2 and OpenVR from vcpkg."

Maybe that is the issue?  I am building off of a git clone of OpenVR, maybe
the directory structure is different and the CMake code is only handing the
source code structure. Could be a similar issue for SDL2.

Hi,

Could you please provide more details on how you?re trying to set the
camera parameters?
The way the external camera works is that it ignores the camera position
and focal point parameters if the projection and model view matrices are
set explicitly using vtkExternalOpenGLCamera::SetProjectionMatrix() and
vtkExternalOpenGLCamera::SetModelViewTransformMatrix()

Thanks,
Sankhesh

Hi everyone,
Does anybody know of a mthod to find how out how much surface area two polydata shares or are overlapping. Basically I have 2 objects and I want to find out what percentage they are properly touching each other.
Thanks,

Is there any way that I could get some message out about why it is skipping OpenVR rather than silently skipping it?

Thanks

"Yes, I have SDL2 and OpenVR from vcpkg."

Maybe that is the issue?? I am building off of a git clone of OpenVR, maybe the directory structure is different and the CMake code is only handing the source code structure. Could be a similar issue for SDL2.

After multiple attempts, I have not been able to compile VTK with OpenVR. With the project directory set to the OpenVR directory, I receive the following output. This is expected because vtkObjectFactory is part of the main project.

However, what is not expected is the following when configuring the main project. There is no OpenVR folder in the build directory and no explanation of why. Yes, I have SDL2 and OpenVR from vcpkg.

Hi Sankhesh,

I've tried setting the camera and focal point parameters without using
SetProjectionMatrix() and SetModelViewTransformMatrix(), and I've also
tried just calling SetProjectionMatrix() and SetModelViewTransformMatrix()
by themselves. Neither approach seemed to have an effect on the scene. I
was looking through the documentation and was wondering if I need to use
the function vtkCamera::vtkSetUseExplicitProjectionTransformMatrix(bool) to
solve the problem?

Thanks,
Elaine

Subject: [vtkusers] vtkTextureObject bind error
Message-ID: <1500569102114-5744068.post@n5.nabble.com>

This is an ongoing issue I have had since starting my project with VTK 6.3
until today when I am using 7.1.1.  I have seen it mentioned many times by
other users and no one has been able to help.  I even had VTK paid support
for over a year and even working directly with a Kitware engineer failed to
the problem.

There are many times when I will display a 3D object and numerous errors
related to vtkTextureObject will be generated.  The result is that I get
notified of these errors and my object does not display.

The first problem occurs here, on the second line, assert(this->Handle). 
Note that nowhere in my code do I explicitly use a vtkTextureObject.  It is
my understanding that VTK must use this object for displaying text, even
when the text is a solid color, so if I don't specify a texture then a
default is created.

void vtkTextureObject::Bind()
{
  assert(this->Context);
  assert(this->Handle);
  ...
}

The next error occurs here:

void vtkTextureObject::SendParameters()
{
  assert("pre: is_bound" && this->IsBound());
  ...
}

Unfortunately, I am unable to provide sample code that reliably demonstrates
this issue.  The software it is used in is a commercial release which is
quite large and not open-source.  Out of the hundreds of users of this
software, approximately one half report the bug.  Many attempts at creating
a demo had varying results.  I was able to create one demo that failed on
half the computers I tried it on but no one at Kitware could duplicate them. 
There are many things I tried at the suggestion of Kitware and I will try to
organize a list at some time in the future.

Hi Elaine,

You shouldn?t have to set that flag for using the matrices set on the
external camera. Could you share some sample code that doesn?t work?

Thanks,
Sankhesh

Hi Elaine,

I didn?t see anything obvious in your sample code so decided to look more
closely at the external renderer implementation. Its been a while since I
looked at that code and my memory was rusty.

You don?t need the external renderer if you are driving the OpenGL scene
via VTK. Think of the external renderer as glue code that synchronizes the
external OpenGL scene with VTK. It makes sure that the camera used is an
external camera and overrides the camera parameters with what it finds in
the external OpenGL scene. You need it in cases where something else is
controlling the OpenGL camera and you?d like the VTK scene to be up-to-date
as well; e.g. virtual reality systems where the main application updates
OpenGL camera parameters.

In your case, you can simply instantiate a vtkRenderer and set it on the
vtkExternalOpenGLRenderWindow via vtkRenderWindow::AddRenderer(vtkRenderer*
ren). The rest of the code should work as expected - except that the active
camera would be of type vtkOpenGLCamera instead of vtkExternalOpenGLCamera.

Hope that helps.

Hi Mike,
There is no way to change this behavior for vtkImageBlend.? One solution is to use a dummy image as input 0 (same dimensions as your first image, but with RGBA set to 0,0,0,1 for all pixels), and then add your two images as inputs 1 and 2.
?- David?

Hi, I'm using vtkImageBlend to blend two?vtkImageMapToColors. Right now if I change the opacity map of the first vtkImageMapToColors (via lookup table), it adjusts the entire alpha of the output (so for example hiding the first one hides both of them). Is there a way to prevent vtkImageBlend from assigning the opacity of the first element to the output? I've tried using the "compound" blending mode in case that would help, but the screen is blank then. Any help would be great!
This is a simplified version of the code I'm using:
vtkSmartPointer<vtkImageMapToC olors> imapper1 = vtkSmartPointer<vtkImageMapToC olors>::New();imapper1->SetLookupTable(lut1) ;imapper1->PassAlphaToOutputOn( );imapper1->SetInputData(image1) ;imapper1->Update();
vtkSmartPointer<vtkImageMapToC olors> imapper2 = vtkSmartPointer<vtkImageMapToC olors>::New();imapper2->SetLookupTable(lut2) ;imapper2->PassAlphaToOutputOn( );imapper2->SetInputData(image2) ;imapper2->Update();
vtkSmartPointer<vtkImageBlend> blend = vtkSmartPointer<vtkImageBlend> ::New();blend->AddInputConnection(imap per1->GetOutputPort());blend->SetOpacity(0, 1.0);blend->AddInputConnection(imap per2->GetOutputPort());blend->SetOpacity(1, 1.0);
// If I now render and adjust lut1, it affects the output of blend so the imapper2 image gets affected

After some additional configuration, I now receive the following. However, the OpenVR directory is still not included in the build.

Is there any way that I could get some message out about why it is skipping OpenVR rather than silently skipping it?

Thanks

"Yes, I have SDL2 and OpenVR from vcpkg."

Maybe that is the issue?? I am building off of a git clone of OpenVR, maybe the directory structure is different and the CMake code is only handing the source code structure. Could be a similar issue for SDL2.

CMake Deprecation Warning at ThirdParty/libproj4/vtklibproj4/cmake/policies.cmake:2 (cmake_policy):
The OLD behavior for policy CMP0022 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

Subject: [vtkusers] Trying to build VTK 7.1.1 on CentOS 6 - 'make test' fails
Message-ID: <2ca80f0e-c73e-0dd7-b4bd-5cbcfac7e448@pppl.gov>

I'm a system administrator trying to build VTK 7.1.1 on CentOS 6.9 for 
my users. When I do 'make test', I get a lot of failures. Here's what I 
do to build:

My cmake command:


cmake \
-D CMAKE_INSTALL_PREFIX:PATH=/usr/pppl/vtk/7.1.1 \
-D CMAKE_BUILD_TYPE:STRING=Release \
-D CMAKE_C_COMPILER:PATH=/usr/bin/gcc \
-D CMAKE_CXX_COMPILER:PATH=/usr/bin/g++ \
-D BUILD_SHARED_LIBS:BOOL=OFF \
-D BUILD_TESTING=ON \
-D VTK_Group_Imaging=ON \
-D VTK_Group_Qt=ON \
-D VTK_Group_Tk=ON \
-D VTK_WRAP_JAVA=ON \
-D VTK_WRAP_PYTHON=ON \
-D VTK_WRAP_TCL=ON \
../ \
2>&1 | tee cmake.log

After make completes, I do a  'make test', and get a bunch of segfault 
and 'other fault' errors:

make test 2>&1  | tee test.log

$ grep -i fault test.log | head -n 20
208/2232 Test #208:

.............................................***Exception: SegFault 0.32 sec

That's just some of the errors in total, I get ~1800 errors:

$ grep -i fault test.log | wc -l
1830

When I run 'make test', I'm not doing it on my local server. I'm doing 
it on a remote system, that I ssh into with X11 forwarding enabled. I've 
noticed that, at least for the tests at the start, the tests segfault 
when they're drawing on my screen. Could the SSH/X11 forwarding be part 
of the problem? Could it be that I need to use the older OpenGL 
interface on CentOS 6.9? Should I link to Mesa instead?

Thanks for all your help, from a complete newbie to this list.

Subject: [vtkusers] Building Python support for both Python 2 and Python 3
Message-ID: <090f2ad5-6db8-bc11-4947-cdebf16c3fa9@pppl.gov>

I searched the mailing list archives and coudn't find an answer to this 
question, which I imagine must be quite common on this list:

I support an environment where the users use both Python 2.7 and Python 
3.6 from python.org, as well as the Anaconda2 and Anaconda3  python 
distributions from Continuum Analytics (continuum.io). I need to build 
vtk python modules for these different versions of Python. What is the 
best way to do this?

Is it possible to build just the VTK python module? In a perfect world, 
I should be able to build VTK, install it, and then build the Python 
modules for that version of VTK for the various versions of python I 
support, but that doesn't seem possible.

I imagine I could build VTK with Python2 in my path, and then rebuild it 
with Python3 in my path and have them install in the same location, so 
that the python2 and python3 libraries are both installed, in the VTK 
install directory, but I suspect this might lead to other issues 
elsewhere in the VTK environment.

I imagine I only need to build one module for python 2.7 and both the 
python.org and anaconda2 installations can use the same module, ditto 
for Python 3.6

Any help/suggestions will be greatly appreciated.

Prentice

Hi Elaine,

I see. In that case, you can remove all the code where you?re explicitly
setting the projection and view matrices on the external camera. The
external renderer handles that internally (automatically). The external
renderer is responsible for updating the VTK camera matrices based on the
OpenGL state.

Thanks,
Sankhesh

Robert, 
thanks a lot! I found the culprit by comparing my code to yours (which was
working fine on my system). The problem was that I was overwriting the
vtkRenderWindowInteractor of the main window, instead of using the one
already instantiated from render_window -> GetInterator().

Many thanks, 
Ben

Subject: [vtkusers] vtkProcrustesAlignmentFilter
Message-ID: <CADXmw_M8pnGHAjUHgoN8zfEB9KJjpHp53egfGXXbCjDiP1k0qA@mail.gmail.com>

Hi everyone,

I am using the vtkProcrustesAlignmentFilter to align meshes. It works fine
if the meshes have the same number of points. But the meshes that I use
have different number of points and I know that the
ProcrustesAlignmentFilter needs the same number of points. Therefore I
tried to downsample the number of points of the meshes with the function
cleanPolyData. The downsampling with this function is working but I cannot
set the number of points, only the tolerance. So after this cleaning the
meshes will still have a different number of points.

Do you have any suggestions, how I can downsample the meshes to get the
same number of points?
Because I want to align a set of meshes and therefore the Procrustes
Alignment will be very helpful. With ICP I can only align two point sets.

Thanks in Advance!

Judith

Message-ID: <CANuPjs0U5zHGN8s_02FMDjhAqzwBYhdqhPoNDVfJWZRuRoPyfw@mail.gmail.com>

Dear all,

I visualized several actors using VTK-js. Now I want to read a .json file
and according to the information that it is included there assign different
colors to the actors.

Unfortunately as soon as I try to use the Build-in modules of Node.js I
start getting errors. I didnt manage to find out how do I have to adapt the
"webpack.config.js" (or the "package.json"?) so that it works.

I found somewhere in a forum that it should work by adding " target: 'node'
" to the webpack.config.js but it didnt. Any help would be great!

Thank you!
Cristina

Subject: [vtkusers] VTK 8.0.0 OpenGL2 Invisible surfaces
Message-ID: <1500628878599-5744093.post@n5.nabble.com>

Hi there,

I have found a strange thing switching to the new Backend OpenGL2. When I
render surfaces it seems that only one side of a face is rendered and the
other is not. Front & Backface-Culling is off for those Actors.
This worked perfectly fine with the old Backend. Strangely enough when I
turn on Depth-Peeling in the renderer the faces are rendered correctly,
although none of the actors has any transparency set to it.
It is not driver related because I can reproduce this behaviour with mesa
drivers as well.
Everything takes place under Windows 10. It is an x64 Qt (5.9) app and im
using the QVTKWidget.
I also tried the QVTKOpenGLWidget, but it has the same issues.

Any hints what goes wrong here?

I have done this successfully using C++ and Win32.  For other languages and
OS, I don't know.  With Win32 you can provide dll loading hooks and redirect
any path.

See this page on MSDN for an overview:

https://msdn.microsoft.com/en-us/library/z9h1h6ty.aspx

If you need more detailed information about implementing with VTK, let me
know and I'll post more.

Subject: [vtkusers] triangle - triangle intersection VTK C++
Message-ID: <1500633860968-5744096.post@n5.nabble.com>



I am bit confused how Triangle - triangle intersection works in VTK. When im
using points commented as Shares an edge z = 0 it shows that intersection
doesn't exist, but when im using points commented as Shares an edge z = 5 ,
i am getting intersection. Why is that?

I agree, this is rather confusing. The method vtkIntersectionPolyDataFilter::TriangleTriangleIntersection() sets the isCoplanar flag if the triangles are coplanar, and does not continue with the intersection calculation. In your first example, the triangles are coplanar, whereas in your second example they are not. This is deliberate, as the algorithm employed in vtkIntersectionPolyDataFilter keys off of this isCoplanar flag to traverse a different code path. I will post a MR today to update the documentation to reflect this.

The good news is that there is also a method called vtkTriangle::TrianglesIntersect(). It will not return where the intersection occurs, but should correctly identify both of your triangles as intersecting. 

Would anybody be opposed to me changing the method name vtkIntersectionPolyDataFilter::TriangleTriangleIntersection() to better reflect the fact that it is not entirely general?

+1  but only if you use the VTK_LEGACY macros so people maintaining external apps have a chance to update.

Changing my code from TriangleTriangleIntersect() to TrianglesIntersect(), it
seems to still give me some headache.
I am still bit confused as why it returns 0, even if triangles go in to each
other.
Am i missing something?

Picture: http://imgur.com/a/PMcRk

//1st triangle coordinates
0.0, 0.0, 0.0
5.0, 0.0, 0.0
0.0, 5.0, 0.0
//2nd triangle coordinates
10.0, 5.0, 0.0
5.0, 10.0, 0.0 
1.0, 1.0, 0.0

VTK thinks your surface is translucent. The logic changed in OpenGL2 and so
something in your object indicates the possibility of transparency.  The
options include

- opacity < 1.0
- a lookup table/ color transfer function with some opacity values < 1.0
- a texture map with (< 1.0?) alpha values

You can force VTK to treat your object as Opaque using the ForceOpaqe
option on Actor/Property one of those I think.

My quick thoughts on this are

(1) There have been some fixes in object destruction that may fix this
issue in newer versions of VTK.

(2) I believe vtkSystemTools includes support for printing stack traces. If
this happens on a debug build adding some code there to print a stack trace
prior to the assert (but when the assert will fail) could help narrow down
who is trying to bind a freed (or never created) texture.  If not in System
tools I know windows has fairly lightweight stack printing code that could
be pasted in.

Even with a stack trace these can sometimes be tricky to track down as
sometimes the issue revolves around not who is using the texture after
deletion, but who deleted it. But even then the issue can be tracked down
given time and some extra logging.  If it only happens on release (and not
reldebinfo) builds then it gets tougher.

Is ?it? the vtkIntersectionPolyDataFilter::TriangleTriangleIntersect() method or the vtkTriangle::TrianglesIntersect() method?

If the former, then the triangles are again coplanar. Please see vtkIntersectionPolyDataFilter.cxx:2060, where the method exits without continuing the calculation.

If the latter, then the method should return true for the triangles intersecting. If it doesn?t then this is a bug.

I am using now vtkTriangle::TrianglesIntersect() method.

Link to the source code: https://pastebin.com/7bi1UHtN

Maybe it's something wrong with my code.

Hi Cristina,
ParaViewWeb uses this webpack 1.x loader:
{
    test: /\.json$/,
    loader: 'json-loader',
  },
That should allow you to 'include' a json file in your javascript, and then
you might need to use the built-in JSON.parse() to turn it into an object.

Regards,
Aron

Hi Cristina,

In vtk.js we now use webpack2 (in master at least, you may have picked an
older version though), and the webpack2 documentation states that you no
longer need a loader for json:

https://webpack.js.org/guides/migrating/#json-loader-is-not-required-anymore

Is your project also using webpack2?  In that case you shouldn't need the
json loader.  Also, when you refer to "Build-in modules of Node.js", does
that refer specifically to this:

https://github.com/sindresorhus/builtin-modules

or do you mean something else?

Cheers,
Scott

I can confirm this and have seen the exact same effect here on OpenGL2. 
Likewise, I do not have any transparency set in my colors. 
Interestingly, it does not happen to all vtkPolyData objects that I 
have, but only to some of them.

The platform is similar to mine and I can add that the problem also 
occurs when having openGL Mesa-library-dlls extracted in the executable 
folder, so it does not seem to be a driver problem.

So it might actually be a bug in VTK?

Show me an example and maybe I can show you what VTK thinks is translucent.
Sometimes folks forget about LUTs and textures which can include
transparency.

Alternatively if you set ForceOpaque and the problem goes away, then that
confirms it.

Subject: [vtkusers] image rendering speed
Message-ID: <1500661004209-5744115.post@n5.nabble.com>

Hi! I'm attempting to speed up some image rendering (lots of images in
sequence). Right now rendering time varies a lot, anywhere between 0.001 and
0.059 seconds. Here is my pipeline:

vtkImageData (3D) -> vtkImageReslice -> vtkImageMapToColors (using a lookup
table with color/opacity) -> vtkImageActor -> vtkRenderer -> QVTKWidget

I move the vtkImageReslice through the 3D volume, displaying images as I go.
Is there any way to speed things up? I'm in release mode, using a NVidia GTX
1070. If I could get it to always be less than 0.012 seconds that would be
great. Here are example timings for multiple frames in a row:

0.001 s
0.006 s
0.059 s
0.002 s
0.014 s
0.003 s
0.013 s
0.011 s
0.036 s
0.001 s
0.038 s
0.001 s
0.028 s
0.001 s

It's not even consistent per image. If I run the same test multiple times,
different frames will have very different render times. Any help would be
awesome!

Mike

Be aware that in the new OpenGL2 backend rendering is asynchronous. That is
VTK sends commands to the OpenGL hardware and continues processing. When
the OpenGL hardware gets around to executing those commands is up to the
hardware.

Fortunately there is vtkRenderTimerLog which I believe works quite well as
of a month or two ago. See TestGPURayCastDepthPeeling.cxx in VTK for an
example of its usage. Below is some sample output

Hi,

Thank you for the input. I have tried with new Normals, its the same.
I dont think there is an issue with normals. When Poly data appears on
screen, it will be in darkness(shadow).
I need to turn off every shadow in the renderer. I am using
Renderer->UseShadowsOff(), still no use.

Please someone guide me to turn off all shadows in the scene. Just like how
the Cube source appears in the renderer.

Thanks

This functionality would be really useful. By having such a method, we could more confidently leave the old OpenGL backend and switch to OpenGL2.

It would be great to have it as a built-in option in VTK, and for at least Windows, Linux, and Mac.

I cannot offer much to help, just that if there is a solution available then I can test it on various Windows PCs.

I have done this successfully using C++ and Win32.  For other languages and OS, I don't know.  With Win32 you can provide dll loading hooks and redirect any path.

See this page on MSDN for an overview:

Can you attach a screenshot?  My own experience with VTK tells me that it
is very, very unlikely that you are seeing shadows.  Whenever I see dark
areas in VTK rendering, it is almost always due to the scalars, the
normals, or the winding of the polydata.  It could be that some of your
polygons are wound incorrectly.

Hi,

Due to some reason I am not able to attach screenshot.
But if I rotate and change the angle for the Polydata by interacting with
it, I can see colors correctly, only at certain angles the colors are dark
the way you see for shadows. May be my understanding is wrong, meanwhile I
will try to work with Normals ,Scalars. But if there is a way to turn off
every shadow or add lights to all viewing angles it would be great.

Thanks

Hello, does vtkTriangle::IntersectWithLine(), should return intersection
between coplanar line and triangle, or it only returns intersection on
non-conplanar triangles and lines?

Thanks in advance!

Subject: [vtkusers] "Filling" parts of a volume that are "inside" a set of
	polyhedra
Message-ID: <CAE-7VJkPego+ymMx00gBxHm7Jv0gp3tJ8HbV96Cfwp0o0DKYYg@mail.gmail.com>

Hi all,

I have a set of points describing multiple convex polyhedra. The
polyhedra are for the most part disjoint in space, but they may
intersect slightly in some places.

I need to create an empty voxel volume (all scalars 0), and then
"fill" the voxels that are inside one (or several) of the polyhedrons
with some Perlin noise. I also have access to normals for the faces
constituting the polyhedra, if necessary.

Finally, I also have a single separate polyhedron (non-convex this
time), and as a finishing step, I'd like to fill the voxels that are
inside this polyhedron with a constant scalar value.

Can VTK help me here?

As this is new territory for me as far as VTK goes, any
pointers/advice on how to go about it would be much appreciated.

Cheers,
Elvis

HI Elvis,


ITK would probably handle the mesh to image problem solving space
better, but I have had success with a pipeline composed of
myPolyData => vtkPolyDataToImageStencil => vtkImageStencilToImage =>
write_your_own_myWorkOnMaskImageOfPolyDataContents

There are some limits to what vtkPolyDataToImageStencil and do: you may
need to transform your mesh to an x-y-z aligned image space with sufficient
resolution and
have it satisfy certain topological conditions.

Hi Elvis,

I'd recommend generating a stencil with vtkPolyDataToImageStencil, then
iterating over over all the voxels inside the stencil with
vtkImagePointDataIterator:

http://www.vtk.org/doc/nightly/html/classvtkPolyDataToImageStencil.html
http://www.vtk.org/doc/nightly/html/classvtkImagePointDataIterator.html

The iterator can efficiently give you the pointId for every voxel enclosed
by the polyhedral surface (works for concave as well as convex surfaces).
Once you have the pointId, you can set that voxel to whatever you want.
There's a brief and vaguely relevant description on gitlab: https://gitlab.
kitware.com/vtk/vtk/merge_requests/1118

Many thanks to both of you. I had not found vtkPolyDataToImageStencil
yet, but was looking more towards the concept of implicit functions.
But this sounds like a much better approach, so I think I was right in
reaching out :)

Just one thing I saw in the docs for vtkPolyDataToImageStencil now:

   "The polydata can either be a closed surface mesh or a series of
polyline contours (one contour per slice)."

Does this mean that, since I have a set of closed surfaces (upwards a
100 or so), I'd have to repeat the process David described, once for
each of my polyhedron? Or is there some way to generate a stencil from
many closed surfaces in one go?

You can use as many closed surfaces as you want with
vtkPolyDataToImageStencil, as long as the surfaces don't intersect.
Intersection would break the topological constraints of the filter.

But if you have each polyhedron as a separate vtkPolyData, then iterating
over them all should still be fast, because for each polyhedron you can
ignore all voxels except for the ones that are inside.

Alright. Good to know. My polyhedra will be the result result of a
rigid body physics simulation, and I'm not sure yet whether, in the
final resting state, the bodies may intersect slightly or not, they
probably can.

Okay, then I'll definitely process them one by one.

Hi Ken,

indeed ForcingOpaque on the actors renders all surfaces. And the actors have
a LUT witch contains opacity values < 1. In fact the border pixels have
opacity = 0. Even when I use FroceOpaque these transculent borders are
correctly invisible. What I still do not understand is, why vtk thinks that
one face has to be completely transparent, when ForceOpaque is off and why
it works when Depthpeeling is enabled?
I hope you can shed some light into this.

To the compatibility problems with the new backend on machines that do not
have OpenGL 3.2 like virtual machines.  We solved the problem here (for
windows only, but I dont see why it should not work under linux as well)
like this:

We built the latest MESA driver under Windows and tested the application
with that. Everything runs fine but slow since it is a software renderer. To
test it you can simply copy the opengl32.dll (and maybe the swrAVX dlls) in
the folder of you executable.

When everything works we set up mechanism to load the system opengl when a
3.2 OpenGL context is available and otherwise load the MESA driver.

To do so we build VTK with the Linker-Option /DELAYLOAD:opengl32.dll
This will delay the loading of the specified DLL to the first call instead
of on application start up.
This gives you the chance to use SetDLLDirectory to point to the folder
where the MESA drivers are stored when no sufficient opengl is found and
thus the program will use the mesa drivers.

Now the tricky part is to detect if opengl 3.2 is available. To do so you
need to create a opengl context and see if it worked or failed. To create a
context you have to load the opengl32.dll. This is bad because we want to
switch that. The easiest solution for us was to write a very small program
(<200 SLOC) which checks if opengl in a certain version is available on the
system, since it can load the system opengl32.dll. We call this checker
program on startup of the main application and then decide which DLL to load
for the main app.

Subject: [vtkusers] Check if picked actor is a sphere or not
Message-ID: <VI1PR03MB161630E2AB84C76262019629A6BB0@VI1PR03MB1616.eurprd03.prod.outlook.com>

Hello,

i used this example: http://www.vtk.org/Wiki/VTK/Examples/Cxx/Picking/HighlightPickedActor to change the color of a picked actor to red. In my scene there are many different actors (spheres, cubes,..). Now i want to only highlight actors which are spheres and nothing else. Using PickableOff () for the other things is not suitable for my application, I need to get information about the source of the actor from this->LastPickedActor.

Any ideas?
Thank you very much!

Best Regards

Rendering transparent surfaces is tricky because the order they are
composited impacts the final color. There are a few techniques to address
this issue one of which is depth peeling. When you have depth peeling on,
then even if VTK thinks your surface is transparent, it will render it
correctly.
Without depth peeling, transparent surfaces are rendered by blending the
transparent surfaces all together in whatever order they happen to get
rendered.

To make sure they *all* get blended together VTK turns off writing to the z
buffer for transparent surfaces. So everything in front of the opaque
actors gets rendered and blended together based on their opacity. This is
called alpha blending and if you sort your polygons from back to front it
gives correct results. But sorting is computationally expensive and we do
not do it. Depth peeling is better in that case.

In your case all, or most, of your pixels on the surface are opaque even
though they get rendered in the translucent pass. So the blending operation
ends up being the last thing rendered wins (because they are opaque and z
writing is off).  So if you have a sphere made up of lots of small
triangles what you will see is the last half of the triangles rendered.
Depending on camera direction sometimes that will be the front side of the
sphere and it will look correct, from other directions those triangles will
be the back side and it will look incorrect. Either way you are just seeing
the last half of the triangles rendered (because as in most closed surfaces
there in a front and a back, so you see half). If the triangles were
randomly ordered you would always see a mishmash of front and back.

Hopefully that makes sense. All the faces are being rendered, it is just
that the last face rendered (regardless of front or back) wins.

The Opaque/Translucent setting controls when an actor renders (opaque pass
versus translucent pass) and whether it will write to the zbuffer. Opaque
writes to the zbuffer blocking anything else below it from rendering,
translucent does not write to the zbuffer allowing later polygons
underneath it to be rendered.

Subject: [vtkusers] One question about the implementation of function
 vtkAngleRepresentation3D::BuildRepresentation()
Message-ID: <e16a2b4.c.15d7a6e916d.Coremail.tjlp@netease.com>

Hi, VTK guys,

I check the implementation of vtkAngleRepresentation3D::BuildRepresentation() of the master branch. Line 301 (https://github.com/Kitware/VTK/blob/master/Interaction/Widgets/vtkAngleRepresentation3D.cxx#L301) compares x coordinate of point1 and centerpoint or point2 and centerpoint, if either of them is 0.0, the function will return and the angle value won't be updated.

Now I get an issue raised by this check. If I draw an angle on the sagittal view on the vtkImageViewer2, the x coordinate of the 3 points should be the same. That will cause I can't get the right value.

Why is the comparation added? Although there is some comment "Compute the angle (only if necessary since we don't want fluctuations in angle value as the camera moves, etc.)". I don't understand it.

Would any guys give explainments?
Add @Ken martin as Martin is one of the authors.

Thanks
Liu Peng

I could create 2d ellipse, and render it.
But I have applied vtkLinearExtrusionFilter, my code crash with exit code

Dear Scott and Aron,

thank you for your answers. I was indeed using an older version of Webpack,
but I already upgraded to the newest version. Unfortunately I keep getting
errors when I try to read the JSON file. To this I have to add that
although I have been using vtk for quite a long time now, I am completely
new to javascript.

If I understood correctly with webpack 2 I do not need to add anything to
the webpack.config.js to be able to read json files in the index.js. Is
this right? However, I try to read the json file with the following command
in index.js:

const json = require('./file.json');

apart of that line of code I didnt write anything else related to the
json file. I got the following error:

ERROR in ./src/file.json
Module build failed: SyntaxError: Unexpected token / in JSON at position 146
    at Object.parse (native)
    at Object.module.exports (D:\VTK-JS\node_modules\json-loader\index.js:4:

 @ ./src/index.js 285:13-35
 @ ./src/index.js
 @ multi (webpack)-dev-server/client?http://localhost:8080 ./src/index.js
webpack: Failed to compile.

Thank you very much!!!

Cristina

Message-ID: <CANuVs=JQ9Z5ZHwTGWcCUmuBnH=LQVW1eNuTC-1stwZZ2kYtcwA@mail.gmail.com>

Hello,
Using  vtkImageViewer2 + QVTKWidget and vtkInteractorStyleImage, I created
a DICOM image viewer.  But the image mot filling to the the entire
viewport.  I need the fit the image to the viewport. For this I tried
different suggestion available online, but no effect,
like

    m_vtkImViewer->GetRenderer()->GetActiveCamera()->ParallelProjectionOn();

    m_vtkImViewer->GetRenderer()->GetActiveCamera()->SetParallelScale(1000);


    m_vtkImViewer->GetRenderer()->GetActiveCamera()->Dolly(10);


       m_vtkImViewer->GetRenderWindow()->SetSize(50, 50);


Please help to fit the image in window.

Screenshot of current viewer is attached.

As shown in the screnshot the image is displaying within a margin
inside the viewport.

But the corner annotations (set using vtkCornerAnnotation) are set in
corners of the view port.

Hi Cristina,
I think the 'require' function may be the problem - in vtk-js and
ParaViewWeb, we typically use 'import', like this:

import localPresetImages from '../../presets.json';

Try it that way?
Regards,
Aron

Hi Christina,

I think the issue is inside your JSON file which might not be properly
formed.
To make sure your file is properly formatted, you can use a service like
below to spot the issue quickly.

https://jsonlint.com/

Regarding the "require" or "import" method to ingest your file, they should
both work but we prefer to use the "import" syntax.

Seb

Dear Bill Lorensen

Thank you for your reply!
You've been very helpful.

I have one more question.

I wanted to render axes, and tried this example
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayCoordinateAxes.
But this axes too little for me.

I want to render axes like this picture.
ellipse.png <http://vtk.1045678.n5.nabble.com/file/n5744164/ellipse.png>  

What should i do?

please help me.

I want to make normal vector of the surface of ellipstic cylinder.
To each surface point, I want to render normal vector, and get surface

The current code is this.

Thanks for the solution,
One more doubt in my application, vtkDICOMImageReader is used for reading
all the DICOM files in a folder and setting directly to vtkImageViewer2
 through SetInputConnection(reader->GetOutputPort());. The DICOM images in
the folder might have different size. In this case how can get "Extent"
"Orgin" "spacing" parameters of each image.
Have any methods to extract these from  vtkDICOMImageReader  or vtkImageViewer2
?

I have made a substantial advance in my debugging capabilities but still not
able to solve this.  What I did was to move my entire tomography project
into the VTK solution as an ?example? project.  This allows me to step-into
and debug the VTK dlls, automatically view stack traces, local variables,
class member variables, etc. anywhere that I need and it works great.  The
problem now is that even with this capability I am still unable to locate
and fix the bug.  Much of it has to do with the complexity of the VTK code.

As a reminder:

On some volumes I display I get an assert in the VTK code that says a
certain vtkTextureObject is not valid.  This happens on maybe one in fifty
specific volumes but still accounts for a lot of customer complaints when
the program crashes or fails to display the volume.

Can anyone provide hints as to how I should attempt to debug this now that I
have complete debugging access to the VTK code?

Have you checked if the issue persists with VTK master? That would be my
next suggestion.

Message-ID: <CACDHZEQ6Xpu=aYRQEujOrwmLh-p8UnSBXzVraVnB17RNJ5SM_g@mail.gmail.com>

Hi,

I have .vtk file which i want to read and convert to binary stl file. The
documentation has a function
WriteBinarySTL (vtkPoints *pts, vtkCellArray *polys, vtkCellArray *strips)
. How do I get the information about the vtkpoints and the cellarray?

Hello All,
I want to find out whether a vtkActor is moved from its initial position. I want to compare vtkActor.GetMatrix() with its initial value, but I don't see vtkMatrix comparison API, like overloaded == or equivalent methods. Please suggest.
Thank youRao Ruvva

You'll either need to pull the elements of the matrix out
(aMatrix->GetData()) and compare them, or you can just check the
modification time (someMatrix->GetMTime()) to see if anything has
modified it since the last check, depending on your usecase.

 vtkSTLReader
Message-ID: <1501196717774-5744181.post@n5.nabble.com>

I use the vtkSTLReader to load the data. Can the resolution of the data be
reduced after loading the source or is there any method in vtk 7.1 like
vtkDecimate to reduce the number of mesh triangles.

Any suggestions would be helpful.

Regards,
Jay

Thank you Allie. I used the first approach of comparing individual elements of vtkMatrix4x4.BTW, the vtkMatrix.GetData() does not exist in VtkPython. I had to use GetElement(i,j).

It may not be wrong .
I think what you have done is taken ellipse and extruded it to form
cylinder shape.
If you observe points in your polydata, they are only at the edge of
cylinder shape.

SO normals are drawn only in that region.

You have done too much scaling and hence "arrows" are mixing up to see that
graphics that you see there. I modified your code and you can see normals
drawn correctly. There is output image attached.

Thank you Girish Lande!

Can I not get normals the side surface of about my extruded object?
Should i change the extrusion method to create elliptic cylinder if I want
to get the side surface normals?

But I don't know other ways....

please tell me!

I think you need to find a way to introduce more triangles in your polydata.

One way I can think of is to create multiple successive extrusions instead
of creating one single extrusion. And then append polydata of these
multiple extrusions which will definitely have more points and triangles.
(Please see attached image). Your current polydata is represented by fig.
A. and what you need is polydata as per figure B.

Hi,
I can't say why it does this but I've battled this effect by doing the
following with parallel scale defined as half the size of the image. I
usually do something like this:

extent = new double[3]
{
	image->GetDimensions()[0] * image->GetSpacing()[0] * 0.5,
	image->GetDimensions()[1] * image->GetSpacing()[1] * 0.5,
	image->GetDimensions()[2] * image->GetSpacing()[2] * 0.5
};

imageViewer->GetRenderer()->ResetCamera();
vtkCamera* cam = imageViewer->GetRenderer()->GetActiveCamera();
cam->ParallelProjectionOn();
cam->SetParallelScale(extent[0]);

This gets a little more complicated if you want to use a different
orientation though. Here's some psuedo

if (XY orientation)
    SetParallelScale(extent[0]);
    cam->SetViewUp(0, 1, 0);
else if (YZ orientation)
    SetParallelScale(std::max(extent[1], extent[2] * h / w))
    cam->SetViewUp(0, 0, 1);
else if (XZ orientation)
    SetParallelScale(std::max(extent[0], extent[2] * h / w));
    cam->SetViewUp(0, 0, 1);

Subject: [vtkusers] How to understand the slab thickness, slab resolution,
	spacing
Message-ID: <1501227167522-5744188.post@n5.nabble.com>

Dear all

    I feel confused about some concepts about VTK. Currently, I need to
reslice a 3D data to make the data isotropic, and I use vtkImageSlabReslice.

    Firstly, I read the data, the code is :

vtkSmartPointer<vtkDICOMImageReader> reader =
vtkSmartPointer<vtkDICOMImageReader>::New();

reader->SetDirectoryName("G:\\SNAP_Signal_Analysis\\snap_simulation\\SNAP_TOF_Data\\Chang
Cheng\\TOF");
	reader->Update();

	vtkSmartPointer<vtkImageData> originalData = reader->GetOutput();
	int originalDims[3];
	double originalSpacing[3];
	originalData->GetDimensions(originalDims);
	originalData->GetSpacing(originalSpacing);

    My question is: how does the originalData record the data thickness
information? Because I can not find the thickness from originalData.

    Then, I reslice the data by the following code:

    vtkSmartPointer<vtkImageSlabReslice> resliceFilter =
vtkSmartPointer<vtkImageSlabReslice>::New();
	resliceFilter->SetInputData(originalData);
	resliceFilter->SetOutputSpacing(0.4,0.4,0.4);
	//resliceFilter->SetSlabResolution(0.4);
	resliceFilter->SetInterpolationModeToLinear();
	resliceFilter->SetOutputDimensionality(3);
	resliceFilter->Update();

    Then, I check the output by:

    vtkSmartPointer<vtkImageData> reslicedData = resliceFilter->GetOutput();
	int reslicedDims[3];
	double reslicedSpacing[3];
	reslicedData->GetDimensions(reslicedDims);
	reslicedData->GetSpacing(reslicedSpacing);

     I find that the resliceFilter->SetSlabResolution is critical to get the
correct pixel spacing. Without the resliceFilter->SetSlabResolution, the
reslicedSpacing is (0.4,0.4,1), which means the SetOutputSpacing do not
work. In the SetOutputSpacing(spacing[0],spaicng[1],spacing[3]), what's the
meaning of spacing[3]? It is the thickness, or it is the spacing between
slice?

     Through dicom viewer, I refer to the dicom header, and I am sure that
originalSpacing[3] is the spacing between slice. So, Why
resliceFilter->SetOutputSpacing(0.4,0.4,0.4) do not make
reslicedSpacing[3]=0.4?

     In addition, I find two function in vtkImageSlabReslice:
SetSlabThickness and SetSlabResolution. From some explanation from Internet,
I guess that SetSlabThickness *NumBlendSamplePoints=SetSlabResolution. But,
after test some case, I find it is wrong. And I have no idea about what is
the relationship between slab thickness and slab resolution.

Thank you!

So, I should change cylinder creation method from:
2D EllipsePolyData -> extrude 50.0point -> Convert to PolyData

to:
2D EllipsePolyData -> extrude 0.50point -> Convert to PolyData
-> extrude 0.50point -> Convert to PolyData -> .....until reach to 50.0point

Is this right?

I have created this part, but it doesn't work.
please check.

=============================================
// 2D ellipse
    vtkSmartPointer<vtkPolyData> ellipse =
            vtkSmartPointer<vtkPolyData>::New();
    ellipse->GlobalReleaseDataFlagOff();
    ellipse->Allocate(1, 1);
    ellipse->SetPoints(points);
    ellipse->SetLines(lines);

// extrude 0.5point
    vtkSmartPointer<vtkLinearExtrusionFilter> extrude =
            vtkSmartPointer<vtkLinearExtrusionFilter>::New();
    extrude->SetInputData(ellipse);
    extrude->SetExtrusionTypeToNormalExtrusion();
    extrude->SetScaleFactor(1.0);
    extrude->SetVector(0, 0, -0.50);
    extrude->Update();

// convert to polyData
    vtkSmartPointer<vtkPolyData> ellipticCylinder = extrude->GetOutput();

    double dl = 0.5;

// loop until z_length
    while (dl <= z_length)
    {
        extrude->InitializeObjectBase();
        extrude->SetInputData(ellipticCylinder);
        extrude->SetExtrusionTypeToNormalExtrusion();
        extrude->SetScaleFactor(1.0);
        extrude->SetVector(0, 0, -0.50);
        extrude->Update();

        ellipticCylinder = extrude->GetOutput();
        dl += 0.50;
    }
// next connect to polyDataMapper
================================================

please help me!

Hi All,

  I am new to vtk . The following is the format of my vtk file

I am trying to read it in vtk with the following code:

  std::cout<<"filename:"<<argv[1]<<"\n";
  reader->SetFileName(argv[1]);


  reader->Update();


 I am getting an error: error reading ascii file.possible mismatch of

Hi to all VTK users,
As many of you might have faced the problems with?vtkBooleanOperationPolyDataFilter,?you know that there are many occasions that it really does not work and it is a pain in the neck.
I have done some search and I know there are a couple of other libraries to use for this specific operation, like CGAL, LIBIGL, Cork, etc.
Has anyone ever tried any of the libraries? Can you guide me on which one is smoother or easier to use based on your experience?
Thanks a lot.

A different boolean operation method was recently merged into VTK
master. Please see
http://www.vtk.org/doc/nightly/html/classvtkLoopBooleanPolyDataFilter.html

It would be great to get some feedback from you on whether this
version works better.

Thanks,

Hi Zhang,

To make your data isotropic, I suggest using vtkImageReslice.  I don't see
any reason to use vtkImageSlabReslice, but maybe you can explain in more
detail why the "slab" part is important for your result.

VTK does not record the SliceThickness.  The VTK spacing measures the
distance from the center of one slice to the center of the next slice.  If
you need the thickness, you must get it from the DICOM metadata (e.g. you
could use the vtkDICOMReader from github.com/dgobbi/vtk-dicom, which reads
all of the metadata).

If you use vtkImageReslice, making the data isotropic should be as easy as
this:

        vtkSmartPointer<vtkImageReslice> resliceFilter = vtkSmartPointer<
vtkImageReslice>::New();
        resliceFilter->SetInputData(originalData);
        resliceFilter->SetOutputSpacing(0.4,0.4,0.4);
        resliceFilter->SetInterpolationModeToLinear();
        resliceFilter->Update();

There is no need to call resliceFilter->SetOutputDimensionality(3), since
this is already the default.

I have converted my project to use VTK master (8.1) and the problem persists.

Note again that for current purposes my project is essentially a part of the
VTK build.   I am able to debug, set breakpoints, view call stacks, step
into VTK code, monitor VTK local and class variables, etc.

Unfortunately, I find the VTK code far too complex to track down texture
object binding errors without guidance - especially when it is the VTK code,
not mine, that creates these objects.

Note 1: PDI-TOMO.exe vtkControlBase::Render() is my code that starts the
render process from a Windows WM_PAINT message.  I should not have have
named this class with the vtk prefix (may be confusing) and will probably
change it eventually.

Note 2: This stack trace only includes the render portion of the code - not
adding the objects to the renderer.  I could probably supply that too if
necessary.

Note 3: Remember that this error occurs only on a fraction of the volumes
that are rendered.  Most work fine.

Hi Zhang,

Please explain exactly what you mean by "thickness".  Usually only the
spacing is needed for reslicing, so you need to help me understand why your
situation is different.

Also, always CC your replies to the VTK users list.

Ahh, it seems your graphics card cannot handle the size volume you are
trying to render. I would guess the issue is the 3191 dimension. A few
options come to mind depending on your situation.

1) require a larger graphics card

2) shrink any volumes that to fit in 2048 (that would be my guess for the
largest size on your card)

3) The volume rendering folks may some other tricks to handle this by
streaming or etc

Thanks for all your help.  This is certainly the cause of the crash.

1) require a larger graphics card - Not practical at this point.  We have
numerous customer support issues and we can't tell the to get a new
computer.

2) shrink any volumes that to fit in 2048 (that would be my guess for the
largest size on your card) - Don't know how I would go about doing something
like this.  It's a large and complex program and it seems to me that a
change like this would touch the code widely.  In other words, a major
re-write.

3) The volume rendering folks may some other tricks to handle this by
streaming or etc. - TRICKS ARE WELCOME!

Thanks again

Hi Zhang,

Please CC the vtkusers list in your replies!  Also please use proper
capitalization and punctuation, otherwise I will simply ignore your emails.

In order to average slices to reduce noise, use this vtkImageReslice method:

    resliceFilter->SetSlabNumberOfSlices(N);

where N is the number of slices you want to be averaged.  So, to average
over 10mm when the slices have 0.4mm spacing, use N=25.  The output slice
spacing will still be 0.4mm.

The documentation for all the "Slab" methods for vtkImageReslice starts
here:
http://www.vtk.org/doc/nightly/html/classvtkImageReslice.html#ac46cc094b1fb577d2a3983fa2f90350d

Hi Rick,

You can enable streaming by setting a number of partitions
(vtkOpenGLGPUVolumeRayCastMapper::SetPartitions).

Check-out  the following test
<https://gitlab.kitware.com/vtk/vtk/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTextureStreaming.cxx#L107>,
let me know if you have any questions.

Hi Swetha,

Assuming that your data is a triangle polydata set, all vtkSTLWriter
have to do is set the file type to binary, so as to output as binary
STL file. You don't need to call WriteBinarySTL(). Ex:

vtkSmartPointer<vtkSTLWriter> stlWriter =
  vtkSmartPointer<vtkSTLWriter>::New();
stlWriter->SetFileName(filename.c_str());
stlWriter->SetInputData(polyData);
stlWriter->SetFileTypeToBinary();
stlWriter->Write();

Thanks

Hi all,
In order to introduce more triangles, I don't think that there is any need
to do multiple successive extrusions.
I would suggest using vtkLinearSubdivisionFilter to achieve what I think
you want.

Please see the attached modification of your code.

Note:
1) You need to pass extrude through vtkTriangleFilter then apply
vtkLinearSubdivisionFilter.
2) Experiment with changing numberOfSubdivisions in the attached code.

Regards
    Andrew

Dear David:

    Sorry for not CC to vtkusers list. 

    For vtkImageReslice, if the output spacing[2] = 0.4, I can set the
thickness of resliced image to 0.4*n by set the SetSlabNumberOfSlices to n.
If I want the thickness to be 1mm, n will be 2.5. But the type of n is int,
so n can not be 2.5, which means the thickness can not be 1mm if the
outputspacing[2]=0.4. Am I right?

    On the other hand, I still feel confused about the vtkImageSlabReslice.
What's the meaning of slab resolution and slab thickness? And after set the
output spacing to (0.4,0.4,0.4), why the reslicedSpacing[2] of resliced
image was not 0.4?

        vtkSmartPointer<vtkImageSlabReslice> resliceFilter =
vtkSmartPointer<vtkImageSlabReslice>::New(); 
        resliceFilter->SetInputData(originalData); 
        resliceFilter->SetOutputSpacing(0.4,0.4,0.4); 
        resliceFilter->SetInterpolationModeToLinear(); 
        resliceFilter->SetOutputDimensionality(3); 
        resliceFilter->Update(); 

        double reslicedSpacing[3]; 
        reslicedData->GetSpacing(reslicedSpacing); 

     Best wishes!
zhang qiang

Hi Zhang,

The code for vtkImageSlabReslice shows what SlabThickness and
SlabResolution do:

https://gitlab.kitware.com/vtk/vtk/blob/master/Imaging/
General/vtkImageSlabReslice.cxx#L47

  this->NumBlendSamplePoints = 2*(static_cast<
      int >(this->SlabThickness/(2.0 * this->SlabResolution))) + 1;
  this->SlabNumberOfSlices = this->NumBlendSamplePoints;

and:

  spacing[2] = this->SlabResolution;

The SlabThickness is only used to compute the SlabNumberOfSlices (which is
an integer).  And the SlabResolution overrides the slice spacing.  The
vtkImageSlabReslice filter is not meant to be used as a 3D output filter.

The output slice thickness is always an integer multiple of the output
slice spacing.  This can be tweaked a little with the TrapezoidIntegration
option, but a true fractional slice thickness isn't possible.
http://www.vtk.org/doc/nightly/html/classvtkImageReslice.html#
a9a8fb0ce5f767733bbce72f5be32b409
https://en.wikipedia.org/wiki/Trapezoidal_rule

A different way to reduce image noise when reslicing is to use
vtkImageSincInterpolator with SetBlurFactors:
http://www.vtk.org/doc/nightly/html/classvtkImageSincInterpolator.html#
aa662697dec4b11dacfc21e062fb1551f
but the result will be different from thick slicing.

 - David

I built VTK Master today and tested the vtkLoopBooleanPolyDataFilter, it worked better for basic geometries and extruded objects, but takes the same amount of time to process for complex polydatas and also does not keep the normal data array.

Hi kenichiro,

   Thanks for the reply. I have a problem reading the .vtk file .Below is
the code which I had used to read .vtk


vtkSmartPointer<vtkGenericDataObjectReader> reader =
      vtkSmartPointer<vtkGenericDataObjectReader>::New();
  std::cout<<"filename:"<<argv[1]<<"\n";
  reader->SetFileName(argv[1]);


  reader->Update();


 I am getting an error: error reading ascii file.possible mismatch of

The suggested solution (setting partitions) does not work for me. Although
the error message indicating invalid texture dimensions is gone there is
still a failure to bind the texture.

This error message (in vtkVolumeTexture::SafeLoadTexture()) is no longer
seen:

ERROR: In E:\VTK\VTK-master\Rendering\VolumeOpenGL2\vtkVolumeTexture.cxx,
line 720
vtkVolumeTexture (10FA4E18): Invalid texture dimensions [53, 54, 3191]

This assert (in  vtkTextureObject::Bind()) still fires:

assert(this->Handle);

ERROR: In E:\VTK\VTK-master\Rendering\OpenGL2\vtkTextureObject.cxx, line 549
vtkTextureObject (1421E0A8): failed at glBindTexture 1 OpenGL errors
detected

Hi Swetha,

Your code may not be wrong. I regret to say that there is no way to
know if the file can be read.

I highly recommend that you look into a PDF of VTK file formats.

Could you run the texture-streaming test?

$ ctest -R CastTextureStreaming

It might help to know if that also fails.

Subject: [vtkusers] Reset window level and window width (vtkImagevewer2 +
	vtkInteractorStyleImage)
Message-ID: <CANuVs=+bDEcr++SQi0B9Cvj_Gx_-ymZ5LMydkTopY306fY=RYQ@mail.gmail.com>

Hello all,
I'm using QVtkWinget+vtkImageviewer2+custom inherited vtkInteractorStyleImage
to develop an DICOM imageviewer  ( same as ReadDICOMSeries vtk example).
The images in the series are loaded in viewer with mouse scroll. Also left
mouse move changes the window level and width.
 In my imageviewer i need to reset the windowlevel and window width in
viewer to custom values while loading a new image in series(and also in a
predefined even like Crtl+R key).
The values to be set are default values of DICOM meta data (For that I'm
reading the window values from dicom meta data)
The problem is I can't reset the window level and window width values of
vtkImageviewer2. I tried with vtkImageViewer2->SetColorWindow  and
vtkImageViewer2->SetColorLevel methods, but it working on first image only.
After that while loading the remaining image in the series (using the mouse
scroll), the window level & width in viewer remaining in the last  set values,
later call to  vtkImageViewer2->SetColorWindow  and
vtkImageViewer2->SetColorLevel
methods not updating in viewer. (but can change the values through mouse,
but intention is to change to a custom value.)
I tried with the below method after setting the window values but nothing
updating the new values in viewer.
vtkImageViewer2->Render();
 vtkImageViewer2->RemoveAllObservers();

vtkImageViewer2->GetRenderer()->ResetCamera();

vtkImageViewer2->->RemoveAllObservers();


How can set custom window width and values to the vtkImageViewer2?

Where  have to set it in vtkImageViewer2/ vtkInteractorStyleImage

Please help..

I tried running ctest but no matter what I do it always says "No tests were
found!!!"  I tried running it from several folders (bin, testing, etc.) but
still the same message.  It seems that I have built VTK with testing enabled
(BUILD_TESTING check set) so a I am out of ideas.  What is the correct way
of running ctest?

If you built vtk with BUILD_TESTING checked then you should be able to
run it from the build directory as

C:\YOUR_VS_SOLUTION_DIR>ctest -R TextureStreaming -C Debug

Change the last parameter to your particular configuration.

Are you setting a volume mask or are you only rendering input data?

With the additional information you supplied I was able to successfully run
ctest.  

100% tests passed, 0 tests failed out of 1

Yes, I am using a volume mask.

Using masks with streaming enabled might be the issue. Currently, only the
input supports
texture streaming.  Could you try rendering without any masks?

Thanks Ken. Unfortunately vtkRenderTimerLog doesn't appear to be in VTK as
far as I can tell? I'm using VTK 7.1.0.

Subject: [vtkusers] How to split large models into smaller pieces when
 exporting the scene?
Message-ID: <1501555747988-5744232.post@n5.nabble.com>

Hi, I'm using VTK with Unity 3D. 
I use vtkX3DExporter to export my VTK scene, and rebuild the meshes in
Unity. 
Unity and maybe all game engines don't support single models that have more
than 65536 vertices. I must split large models into smaller pieces. 
Is there an existing method to do this, or do I need to implement this
myself? If the latter, could you give me some hints?
