Bill brings up many good points. In particular references to the old
mailing lists and such. I am a big fan of making information available
through multiple access vectors so it can be found and accessed through
different means.

The harm of keeping the list open is in splitting the attention of the
community.

Note that when we close the mailing list, we really mean "turn off the
ability to post anything new to it". I think with some sort of response
that directs people who try to discourse. The archives will still be
available forever.

+1

(In Qt they recently had a debacle where they accidentally
regenererated their ML archives, creating broken links all over the
place (forums, commit messages, bug reports et.c.) and had to back out
and restore it.)

I think you mean MarkMail? I don't think Stack Overflow mirrors mailing
lists.

vtk.org/mailing-lists now redirects to vtk.org/community-support, taking
care of those links. For other links, we can add text to the email list
signup pages (e.g. https://vtk.org/mailman/listinfo/vtkusers) directing
people to Discourse.

You should be able to reply to emails and it will post on Discourse, no
login required.


> What is the harm in keeping the lists?

Having more VTK support sites diffuses VTK knowledge and splits the
community. Having more sites/lists makes it harder for people with
questions to search for answers in previous posts. I realize that is also
an argument for not having started the VTK Discourse at all, but I think
the advantages of Discourse (which we can and have debated) are greater
than that of the mailing list.

I think my biggest concern is references to the old lists, including places
in mailman where you can sign up. For me, a search of "vtk mailing lists"
brings up the mailman user signup list #2 in the rankings:
vtkusers Info Page <https://vtk.org/mailman/listinfo/vtkusers>

and #3 in the rankings:
vtk.org Mailing Lists <https://vtk.org/mailman/listinfo>
with links to the user, developer, and vtkm lists.

(Fortunately the #1 ranking is the Community Support | VTK page which links
to the forums which is great.)

Also I suspect that there are external courses, presentations, notes, etc.
out there which refer to the mailman list(s). So I suggest that these
mailman-related sign up sites etc are modified with with an informative
redirect to VTK resources especially the forums. Right now you can sign up
and it initially acts like expected..... this might generate some
frustration in an unsuspecting user.

Subject: [vtkusers] Feature edges extraction with associated dihedral angle
Message-ID: <CAB8-E4ArrRd9xA7MBQe4O5j9=oPY6=Nfgyd64itGPOE8NvkU=A@mail.gmail.com>

Dear VTK users,

I am working with a vtkPolyData made of triangles.

I would like to identify the feature edges WITH:

- the two associated triangle indices to store their normals
- the corresponding dihedral angle.

These results could be respectively CellData vectors and scalar of
vtkFeatureEdge output, for example.


1) Using vtkFeatureEdge returns a new vtkPolyData with no link with
original triangles. Do I have to iterate over points of the generated
vtkFeatureEdge to find the closest triangle on vtkPolyData. But it does not
seem smart at all.

2) Rewrite vtkFeatureEdge class with only FeatureEdges=1 seems possible.
But is there a smarter solution?

3) Can vtkPolyDataNormals brings a smarter answer?

Thanks you for reading and your future answer!

Guillaume

Hi,

You could easily make that by the module "segment editor 
<https://slicer.readthedocs.io/en/latest/user_guide/module_segmenteditor.html>" 
(smoothing option) of 3D slicer <https://www.slicer.org/>, or by command 
(in 3dslicer):

|segmentEditorWidget.setActiveEffectByName("Smoothing") effect = 
segmentEditorWidget.activeEffect() 
effect.setParameter("SmoothingMethod", "MEDIAN") 
effect.setParameter("KernelSizeMm", 6) effect.self().onApply() HTH,

Hi Marco,

A good introduction to using CMake to build projects can be found here: https://cmake.org/runningcmake/ . The source directory contains VTK?s source code and the build directory is an empty directory in which VTK?s binaries will be built.

Sincerely,
T.J.

I think I have linked properly the libraries and header files to my project.
Can you help me how to fix that?

Subject: [vtkusers] Reslice a volume using the transformation of the
 rendering
Message-ID: <1551654451787-0.post@n5.nabble.com>

Hi!

I want to apply the rotation that the user does in the rendering, to the
volume. Thus, I want to store it in the position that the user wants.
However, when I apply the transformation and render it, the volume is not
oriented as in the orientation seen in the first window.

Can you help? Any suggestion?

Here is my code



vtkSmartPointer<vtkTIFFReader> reader =
vtkSmartPointer<vtkTIFFReader>::New();
reader->SetFileName("volume.tif"); // Multi slice TIFF
reader->Update();
vtkSmartPointer<vtkImageData> image = reader->GetOutput();

// Color transfer functions

vtkSmartPointer<vtkFixedPointVolumeRayCastMapper> volumeMapper =
vtkSmartPointer<vtkFixedPointVolumeRayCastMapper>::New();
volumeMapper->SetInputConnection(reader->GetOutputPort());

vtkSmartPointer<vtkVolume> volume = vtkSmartPointer<vtkVolume>::New();
volume->SetMapper(volumeMapper);

// (To the best of my knowledge) I define this Interactor to rotate the
volume, not the view or camera
vtkSmartPointer<vtkInteractorStyleTrackballActor> style =
vtkSmartPointer<vtkInteractorStyleTrackballActor>::New();

vtkSmartPointer<vtkRenderer> ren1 = vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renWin =
vtkSmartPointer<vtkRenderWindow>::New();
renWin->AddRenderer(ren1);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renWin);
renderWindowInteractor->SetInteractorStyle( style );

ren1->AddViewProp(volume); //Or AddVolume?
ren1->SetBackground(0,0,0);
ren1->ResetCamera();

renWin->SetSize(800, 800);
renWin->Render();
renderWindowInteractor->Start();

//After the user close the window, I want to apply the transformation to the
original volume
//Probably, my problem is in this section of code

vtkSmartPointer<vtkMatrix4x4> matrixRot =
vtkSmartPointer<vtkMatrix4x4>::New();
volume->GetMatrix(matrixRot);

vtkSmartPointer<vtkImageReslice> reslice =
vtkSmartPointer<vtkImageReslice>::New();
reslice->SetInputConnection(reader->GetOutputPort());
// Rotate about the center of the image?
vtkSmartPointer<vtkTransform> transform =
vtkSmartPointer<vtkTransform>::New();
transform->SetMatrix(matrixRot);
reslice->SetOutputOrigin( reader->GetOutput()->GetOrigin()[0],
reader->GetOutput()->GetOrigin()[1], reader->GetOutput()->GetOrigin()[2]);
reslice->SetResliceTransform(transform);
reslice->SetInterpolationModeToCubic();
reslice->SetOutputSpacing(
reader>GetOutput()->GetSpacing()[0], reader->GetOutput()->GetSpacing()[1],
reader->GetOutput()->GetSpacing()[2]);
reslice->SetOutputExtent(reader->GetOutput()->GetExtent());
reslice->Update();



Thanks in advance.
Lucas

Hi Guillaume,

I do not know of a smarter way to get what you want than to do one of the
solutions you have described. You could modify vtkFeatureEdges to produce
the output you want and submit it in a merge request on GitLab [1] and make
the feature available to future users of the class.

By the way, we are transitioning from the mailing list to
https://discourse.vtk.org/. Please post future questions there.

Thanks,
Cory

Hi S?bastien,

Thanks for your response.

Actually, I don't understand why I still have the use of a Timer, neither.
But the point is that if I put the panel3d.resetCamera() command outside
the Timer, it doesn't work :-(.

Hope I can figure out why soon and any hint on this purpose will be really
appreciated.

Anyway thanks again for your time.

jMax

You can do it via an invokeLater or anything that will schedule the
execution in the EDT.

Message-ID: <DB6PR0902MB1768719672AB56CE810CCFEDB7720@DB6PR0902MB1768.eurprd09.prod.outlook.com>

Dear all,

I try to extract the boundary nodes of an unstructured grids. Based on the example
https://vtk.org/Wiki/VTK/Examples/Cxx/Meshes/BoundaryEdges
I used the following code:

vtkSmartPointer<vtkUnstructuredGrid> grid = vtkSmartPointer<vtkUnstructuredGrid>::New();
vtkSmartPointer<vtkDataSetSurfaceFilter> filter = vtkSmartPointer<vtkDataSetSurfaceFilter>::New();
vtkSmartPointer<vtkFeatureEdges> edges = vtkSmartPointer<vtkFeatureEdges>::New();

/* load mesh into grid */
...

/* extract the boundary points */

filter->SetInputData(grid);
filter->Update();
edges->SetInputData(filter->GetOutput());
edges->BoundaryEdgesOn();
edges->FeatureEdgesOff();
edges->NonManifoldEdgesOff();
edges->ManifoldEdgesOff();
edges->Update();

vtkSmartPointer<vtkPolyData> polyData =  edges->GetOutput();


When I print out the number of the points in polydata (polydata->GetNumberOfPoints()) I obtain 0, i.e.
polydata is empty. When I comment out the lines

edges->NonManifoldEdgesOff();
edges->ManifoldEdgesOff()

then I get some subset of points in polydata extrated from the grid but when I visualize these points I see that some boundary points are missing and there are some inner nodes in polydata. Thus
polydata does not contain the exact set of the boundary points of the grid.
Now I am not sure if this is the correct way to extract the boundary points from an unstructured grid
and I would like to ask if there is any. Thank you very much for your help!

Kind regards,
Zoltan

Hi Zoltan,

Would you mind posting your question to https://discourse.vtk.org?
Community support for VTK is transitioning to that forum, so you may be
more likely to get an answer there.

Thanks,
Cory

I have the following code in my main() to disable vtk warnings output.

    vtkObject::GlobalWarningDisplayOff();

However, vtkOutputWindow still pops useless warnings up.
What is wrong?

Subject: [vtkusers] SSAA and FXAA
Message-ID: <1551818251098-0.post@n5.nabble.com>

Hi experts,

I'm using vtk 8.1 and am having a little bit of a trouble getting
anti-aliasing working.

When using the FXAA approach, the graphic remains the same regardless of the
FXAA options I pass to the renderer.

vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkOpenGLRenderer>::New();
renderer->SetUseFXAA ( true );
auto options = renderer->GetFXAAOptions();
options->SetSubpixelBlendLimit ( 0.75 );
options->SetHardContrastThreshold ( 0.045 );
options->SetRelativeContrastThreshold ( 0.125 );
options->SetEndpointSearchIterations ( 12 );
options->SetSubpixelContrastThreshold ( 0.25 );
options->SetUseHighQualityEndpoints ( true );

<http://vtk.1045678.n5.nabble.com/file/t342714/fxaa.png> 


When using the SSAA render pass approach I have depth buffer issue where the
surfaces of a primitive cube get rendered in an incorrect order. I came
across this depth peeling fix but it didn't work for me unfortunately.

http://vtk.1045678.n5.nabble.com/vtk-developers-QVTKOpenGLWidget-SSAA-pass-breaks-depth-peeling-td5746428.html


vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkOpenGLRenderer>::New();
renderer->SetBackground ( 0.615f, 0.639f, 0.666f );

vtkNew<vtkRenderStepsPass> basicPasses;
vtkNew<vtkSSAAPass> ssaa;

vtkSmartPointer<vtkDepthPeelingPass> depthPeel = vtkSmartPointer <
        vtkDepthPeelingPass > ::New();
vtkSmartPointer<vtkTranslucentPass> translucent = vtkSmartPointer <
        vtkTranslucentPass > ::New();
depthPeel->SetMaximumNumberOfPeels ( 0 );
depthPeel->SetTranslucentPass ( translucent );
basicPasses->SetTranslucentPass ( depthPeel );


ssaa->SetDelegatePass ( basicPasses );
renderer->SetPass ( ssaa );
renderer->SetUseDepthPeeling ( true );
renderer->SetMaximumNumberOfPeels ( 0 );

<http://vtk.1045678.n5.nabble.com/file/t342714/ssaa.png> 


I'm not sure what I'm missing and I would greatly appreciate if anyone can
help me spot it.

Thanks,
Chuan

Subject: [vtkusers] INTERPOLATE ON STL: Plotting scalar field on 50 points
 on An 70000-points STL surface
Message-ID: <1551883491980-0.post@n5.nabble.com>

Hello,

I have an STL surface file. The data were sampled on 50 selected points only
(wind tunnel test).
I want to visualize the field as a contour on the STL file.

I know basic stuff on how to use VTK python library. But this task I want it
involves:
- interpolating the field inside the probes-area
- extrapolating outside the probes-area
- then creating the final VTK file.
- maybe triangulation is also needed..

OR, there might be a crazy filter in paraview that can do the whole thing!

Any help would be appreciated..

HFS

I'm not sure what's causing this, enabling FXAA should work out of the box
for all data rendered in the opaque/translucent passes. Have you tried with
the default options? They shouldn't need to be tweaked unless you're having
serious performance / quality issues.

For SSAA, I'm curious why you're setting the maximum number of peels to 0?
That effectively disables peeling and would result in the improper blending
that you're seeing.

HTH,

Thanks for the response Allie. I tried the default options prior to tweaking
the numbers and I also verified the code execution of FXAAFilter inside
vtkOpenGLRender::UpdateGeometry() by stepping through code.

The documentation indicated that a max peel of 0 means no maximum number of
peeling layers. Again I only changed it to zero because the default setting
did not work for me.

//@{
  /**
   * In case of depth peeling, define the maximum number of peeling layers.
   * Initial value is 4. A special value of 0 means no maximum limit.
   * It has to be a positive value.
   */

Sincerely,
Chuan

Ok, just wanted to make sure :)

Ah, yes, you are correct -- I forgot about that.

This is very strange. While stepping through the rendering code, was
anything rendered during the opaque/translucent passes on the renderer that
called FXAA? You can step through vtkOpenGLRenderer::UpdateGeometry() to
check this. If your data is volumetric or rendered in the overlay pass,
FXAA is applied before those passes and won't affect them. It doesn't look
like your scene is set up that way in your attached image, but it's
something to check.

If you're building your own VTK, you can also try running the FXAA test
interactively and see if it's being applied there. Enable testing in CMake
and run

bin/vtkRenderingOpenGL2CxxTests TestFXAAFilter -I

from the build directory. This renders the same scene twice, side-by-side.
One side has FXAA applied, the other does not. Is there a noticeable
difference?

Yes I do see a noticeable difference in the FXAAFilter test as well as in my
own test widget.

<http://vtk.1045678.n5.nabble.com/file/t342714/vtkFXAA.png> 


<http://vtk.1045678.n5.nabble.com/file/t342714/myFXAA.png> 
<http://vtk.1045678.n5.nabble.com/file/t342714/myFXAA2.png> 
I can see that the FXAA algorithm is affecting the grid lines at certain
angles but they aren't as smooth as I'd like them to be.


I stepped through the code and the grid was rendered in the opaque pass as
vtkRenderer::UpdateOpaquePolygonalGeometry returns 1.


Thanks again Allie for looking into this.

Sincerely,
Chuan

Do you need to build the app on CentOS or is it just for client usage?

Ah, ok, so FXAA *is* working then, and not broken.

FXAA (Fast approXimate Anti-Aliasing) is an approximate anti-aliasing
technique that is applied as a post-processing step. Since it is
approximate and operates in screen space, there are some scenes that it
works well on, and others that it doesn't. It sounds like you've found one
that it doesn't handle -- those thin, clustered lines just look like random
noise and not edges to a screen-space algorithm, so it doesn't know what to
do with them.

If you want higher quality anti-aliasing, you'll want MSAA
(vtkRenderer::SetMultiSamples) or SSAA. MSAA is generally preferred and
better tested.

Subject: [vtkusers] VtkImageData 3D setScalar and save to nifti not work
Message-ID: <1552056678007-0.post@n5.nabble.com>

Hello everyone, sorry for my english i'm a french user.

I have a problem with SetScalarComponentFromDouble in vtkImageData, when I
save a vtlImage in png file with dimensions x,y,0 that work nice, 
 imageData->SetScalarComponentFromDouble(x,y,0,0, 128) give me a gray png.

But when I want to add a z dimension and it to nifti file there is no color,
only black on .nii file.
imageData->SetScalarComponentFromDouble(x,y,z,0, 128);//R

I put my code here : 

#include <vtkSmartPointer.h>
#include <vtkDoubleArray.h>
#include <vtkImageData.h>
#include <vtkPointData.h>
#include <vtkPNGWriter.h>
#include <vtkImageCast.h>
#include <vtkNIFTIImageWriter.h>

int main(int, char *[])
{
  // Create an image data
  vtkSmartPointer<vtkImageData> imageData =
vtkSmartPointer<vtkImageData>::New();

  // Specify the size of the image data
  imageData->SetDimensions(120,121,122);
  imageData->AllocateScalars(VTK_UNSIGNED_CHAR,1);

  int* dims = imageData->GetDimensions();
  std::cout << "Dims: " << " x: " << dims[0] << " y: " << dims[1] << " z: "
<< dims[2] << std::endl;

  for (int x = 0; x < dims[0]; x++)
  {
    for (int y = 0; y < dims[1]; y++)
    {
      for (int z = 0; z < dims[2]; z++)
      {
        // double* pixel =
static_cast<double*>(imageData->GetScalarPointer(x,y,0));
        // std::cout << pixel[0] << "  ";
        // pixel[0] = 128;
        // pixel[1] = 0;
        imageData->SetScalarComponentFromDouble(x,y,z,0, 128);//R

      }
    }
  }


  vtkSmartPointer<vtkNIFTIImageWriter> writer =
vtkSmartPointer<vtkNIFTIImageWriter>::New();
  writer->SetFileName("label_7235_test.nii.gz");
  writer->SetInputData(imageData);
  writer->Write();

  // This should also work:
  // min = vtkImageData->GetOutput()->GetScalarRange()[0] and max =
GetScalarRange()[1].
  return EXIT_SUCCESS;
}

Hi Allie,

I couldn't find vtkRenderer::SetMultiSamples in the doc. However I've tried
vtkOpenGLRenderWindow::SetMultiSamples and
vtkOpenGLRenderWindow::SetGlobalMaximumNumberOfMultiSamples without having
any luck. Are there other setup required besides setting the multi-sample
size?

Thanks,
Chuan

Ah I figured out why MSAA didn't work for me. I needed to call
SetGlobalMaximumNumberOfMultiSamples before setting the QSurfaceFormat since
QVTKOpenGLWidget::defaultFormat() is dependent on that global max multiple
sample value.


//-----------------------------------------------------------------------------
QSurfaceFormat QVTKOpenGLWidget::defaultFormat()
{
  QSurfaceFormat fmt;
  fmt.setRenderableType(QSurfaceFormat::OpenGL);
  fmt.setVersion(3, 2);
  fmt.setProfile(QSurfaceFormat::CoreProfile);
  fmt.setSwapBehavior(QSurfaceFormat::DoubleBuffer);
  fmt.setRedBufferSize(1);
  fmt.setGreenBufferSize(1);
  fmt.setBlueBufferSize(1);
  fmt.setDepthBufferSize(1);
  fmt.setStencilBufferSize(0);
  fmt.setAlphaBufferSize(1);
  fmt.setStereo(false);
* 
fmt.setSamples(vtkOpenGLRenderWindow::GetGlobalMaximumNumberOfMultiSamples());*
#ifdef DEBUG_QVTKOPENGL_WIDGET
  fmt.setOption(QSurfaceFormat::DebugContext);
#endif
  return fmt;
}




// MSAA is fixed by adding these two lines before creating any
QVTKOpenGLWidget
vtkOpenGLRenderWindow::SetGlobalMaximumNumberOfMultiSamples ( 8 );
QSurfaceFormat::setDefaultFormat ( QVTKOpenGLWidget::defaultFormat() );

Thanks Allie,
Chuan

Subject: [vtkusers] VTK for visualizing 3D Networks
Message-ID: <1552226456737-0.post@n5.nabble.com>

Hi all!
I am relatively new to VTK but still surprised by the opportunities provided
by the visualization tool kit. For this reason, I am currently trying to
visualize a network using VTK. I saw some youtube videos concerning this
objective, but I was not able to achieve this objective and struggled hard
the last month..

What I did so far:
-I used networkx (python) to calculate the 3D positions of the node
-Python VTK to plot spheres which represent the nodes and tubes which
represent the edges. 

What I am not able to do:
-I have information about the nodes which I would like to use to define the
importance (=size?) of the nodes. Furthermore, this information is used to
calculate the edge weigths.
-Regarding the edge weights, it would be great to use this information for
defining the tube color/diameter.

I already found some threads directing to the MutableUndirectedGraph class
for example. However, it seems to me that there is not clear way of doing it
in a 3D manner.

Maybe someone of you has some experience regarding this and could give me a
helping hand?
I would be really grateful!

Thanks and cheers
Benny

Subject: [vtkusers] world coordinates do not give the correct dicom
 coordinate
Message-ID: <1552311738686-0.post@n5.nabble.com>

Dear all,

I want to do segmentation with itk and i would like to select a seed using
vtk with the mouse. I get the coordinates in world coordinates

			int x = this->Interactor->GetEventPosition()[0];
			int y = this->Interactor->GetEventPosition()[1];
			std::cout << "(x,y) = (" << x << "," << y << ")" << std::endl;

			seeds[0] = x;
			seeds[1] = y;

but when i want to use it as a seed for itk i see it is the wrong place. I
tried the transformphysicalpointoindex but the result is even worst

		bool isInside =
			extractFilter->GetOutput()->TransformPhysicalPointToIndex(coordinate_vtk,
coordinate_itk);
		if (isInside) {


			ImageType::PixelType pixelValue =
extractFilter->GetOutput()->GetPixel(coordinate_itk);
		}

Any help about the coordinates in vtk?

Thanks

Hello,

Would you mind posting your question to https://discourse.vtk.org?
Community support for VTK is transitioning to that forum, and you are more
likely to get an answer there.

Thanks,
Cory

Message-ID: <1552402288875-0.post@n5.nabble.com>

Hi guys! Im new to vtk...i have 199 dicom images that i rendered in 3D. Now i
have to 'cut' this volume along the axial, sagittal and coronal plane...i
think i should use these 2 functions 
SetDataExtend 
SetDataSpacing
bui i dont know how they work! My images are 512x512 but how can i get this
information from the images so that if i use images with different sizes i
wont have problems?
SetDataSpacing wants the space between each slice in pixels??

Thank u for your answers! :D

Subject: [vtkusers] How to create resliceAxes from two points in a curve?
Message-ID: <1552418540207-0.post@n5.nabble.com>

I would like to use vtkImageReslice to get the cross section of a curve at a
point P0. 

To compute the reslixeAxes, I would like to use P0 and its neighboring point
P1 to decisde the direction. 

As you know, resliceAxes is a vtkMatrix4x4. I think it should be somehting
as:

A, B, C, P0.x
D, E, F,  P0.y
G, H, I,  P0.z
0,  0, 0,   1

Can anyone let me know how to compute the value of {A, B, ... I}  based on
P0 and P1? 

Thank you!

Message-ID: <BEEE8507-106D-43B8-AD8A-6A325256F599@ic.ac.uk>

Hi,

I?m having some issues getting my remote rendering working. It all works perfectly fine with the the default cone from vtk (code from here: https://github.com/dmreagan/vtk-remote-render ), but when I adapt the code to use my own model with interpolation, I get the error:

"WebSocket connection to 'ws://localhost:1234/ws' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED?

I can see the serve side has rendered, but the client side is blank.

My code is below, any help would be much appreciated!

Many thanks,
Shruti

This module is a VTK Web server application.
The following command line illustrates how to use it::

$ vtkpython .../vtk_server.py

Any VTK Web executable script comes with a set of standard arguments that
can be overriden if need be::
--host localhost
Interface on which the HTTP server will listen.

--port 8080
Port number on which the HTTP server will listen.

--content /path-to-web-content/
Directory that you want to serve as static web content.
By default, this variable is empty which means that we rely on another server
to deliver the static content and the current process only focuses on the
WebSocket connectivity of clients.

--authKey wslink-secret
Secret key that should be provided by the client to allow it to make any
WebSocket communication. The client will assume if none is given that the
server expects "wslink-secret" as the secret key.

Subject: [vtkusers] Positioning camera perpendicular to image slice in
 rotated volumes
Message-ID: <1552439433854-0.post@n5.nabble.com>

I have MRI scans which are strongly rotated (direction of 
ImageData is not identity matrix). How to set initial position and viewUp of
camera, so it can be perfectly perpendicular to imageSlice in vtk.js?  
My idea is to:
- get coords of point in the middle of volume and set it as focal point 
- calculate position camera so that direction of projection is perpendicular
to image slice plane
- orthogonalizeViewUp in camera. 

However, I don't want to reinvent the wheel - if there is ready solution in
API I'd be very thankful for any help.

Hi Benny,
Have you seen this?
https://www.westgrid.ca/events/westgrid_online_workshop_3d_graphs_networkx_vtk_and_paraview
It certainly shows that what you want is possible....
I'd also advise looking at more of the VTK examples - I think there's a
Glyph Mapper which will change the size/color of the spheres based on a
data value for you.
HTH,
Aron

You can use vtkMath::Perpendiculars(A,B,C,0) to generate the other two
directions, where A is p0-p1 or p1-p0

Subject: [vtkusers] Rotate vector around center, python
Message-ID: <1552571425672-0.post@n5.nabble.com>

I am using VTK and Python for a project related to my studies.

I am given the following point centerOfRotation and the orientation degrees,
as well as the vector [1, 0, 0]. Now I want to rotate the vector so it
"points" in the direction specified by degrres and then translate it to the
point p.

centerOfRotation = [314.848717879, 283.085686693, 423.900139245]
degrees = [-7.93947167694, -0, 171.098864823]
vector = [1, 0, 0]

transform = vtk.vtkTransform()
transform.Identity()

transform.PreMultiply()
transform.Translate(centerOfRotation)
transform.RotateZ(degrees[2])
transform.RotateX(degrees[0])
transform.RotateY(degrees[1])
transform.Translate(-centerOfRotation[0], -centerOfRotation[1],
-centerOfRotation[2])

newPos = [0]*3
transform.TransformPoint(vector, newPos)
The centerOfRotation and degrees are extracted from another program, in the
other program the second point(newPos) should be beneath the first
point(centerOfRotation). But with the code given above, the second point is
located above the center of rotation. I hope someone can point me in the
right direction. Thanks a lot !

BTW: I am given another information by the other program: YSymmetry=1. I am
not really sure what that means though.

Note: I am neither a math nor computer student and my math skills are
somewhat rusty. Right now I dont have the time to study the math, so if you
could point me in the right "coding" direction I would appreciate it :D

 Thank you very much for the help!?
After reslice, the output is an 2D image, is there anyway to know the coordinate of point? P0 in the 2D image??
or is there any way to make P0 at the center of output 2D image?
Thanks again!

richard anderson via vtkusers <vtkusers at vtk.org> ?2019?3?13??? ??3:28???

I would like to use vtkImageReslice to get the cross section of a curve at a
point P0. 

To compute the reslixeAxes, I would like to use P0 and its neighboring point
P1 to decisde the direction. 

As you know, resliceAxes is a vtkMatrix4x4. I think it should be somehting
as:

A, B, C, P0.x
D, E, F,? P0.y
G, H, I,? P0.z
0,? 0, 0,? ?1

Can anyone let me know how to compute the value of {A, B, ... I}? based on
P0 and P1? 

Thank you!

Subject: [vtkusers] Strange rendering artifacts
Message-ID: <1552611204329-0.post@n5.nabble.com>

Hi,

Trying to work out what could be causing these strange rendering artifacts.
The screen shot here shows the same model rendered on the left with custom
OpenGL and on the right using Vtk 8.1. As you can see there are what look
like small pin holes in the polygon rendering on the Vtk view.

Any thoughts on what to try to remedy this issue appreciated. Thanks.

Interestly if i remove the vtkCleanPolyData (which i'm setting up with the
code below) i don't see the issue with the dots anymore, but the shading now
looks flat shaded so i lost the smooth shading effect.

    vtkSmartPointer<vtkCleanPolyData> cleanPolyData =
        vtkSmartPointer<vtkCleanPolyData>::New();
    cleanPolyData->SetInputData ( polyData );
    cleanPolyData->Update();

Subject: [vtkusers] visualize 3D dicom file
Message-ID: <1552654749788-0.post@n5.nabble.com>

Hi guys! I've read 200 dicom files in ITK (using the example "Reading a 2D
DICOM Series and Writing a Volume" from the itk User Guide) and saved the
volume in a .dcm file in order to open it with VTK.
When I use my code in VTK (reader = vtkDICOMImageReader , mapper =
vtkFixedPointVolumeRayCastMapper) i only see a black window, like my reader
couldnt actually load the volume!

I used the same code in VTK changing SetFileName with SetDirectoryName (in
the dicomReader) and gave the folder of my 200 images and i was able to see
the volume (so the VTK code seems to be good...)...what could be my problem?
I was careful to follow the steps in the itk user guide when i wrote the
volume in a .dcm file....
Thank u for your help!

can you try the GPU Volume RayCast mapper to confirm if the data is loading
correctly using the DICOM volume?

Hi Marco,

that is more of a VTK question than ITK one, best directed at
vtkusers at vtk.org. Also, ITK has migrated to a new forum
<https://discourse.itk.org/>. Please post further ITK-related questions
there instead of this mailing list.

Regards,
D?enan

In fact, VTK also transitioned to discourse a few weeks ago:
https://discourse.vtk.org

So for a better experience and to increase your chances of getting an
answer, you'd better post your question at discourse rather than to
the mailing lists.

Hi Aron, thanks for your response!
Yes, I've already came across this youtube tutorial/Powerpoint slides.
Unfortunately, most of the magic is part of his "writeObjects" functions,
which he does not show neither in his slides nor in his video. Afterwards,
he using the data and working on it using paraview.
My approach was (or still is) to do all work required in Python (.py).

I am not sure if I can edit my post here, so I am adding a second reply


I found a way to do it but I am struggling at converting scalar values to
RGB values for my tubes:
For the spheres I used

/
inputData = vtk.vtkPolyData()
inputData.SetPoints(nodePoints)
inputData.GetPointData().SetScalars(scalararray)
[...]
glyphPoints = vtk.vtkGlyph3D()
glyphPoints.SetInputData(inputData)
glyphPoints.SetSourceConnection(sphere.GetOutputPort())
glyphPoints.ClampingOff()
glyphPoints.SetColorModeToColorByScalar()
glyphPoints.SetScaleFactor(0.05)
/

and for the tubes I currently use:

/
edgeData.SetPoints(points) 
edgeData.SetLines(lines) 
edgeData.GetPointData().SetScalars(scalarvalues)
/

 

However, I am still struggling at converting my scalar tube values to an RGB
array which I can use for the mapper with the command 
/
profileMapper.SetScalarModeToUsePointFieldData() 
profileMapper.SelectColorArray("Colors")
/


I found the class vtkScalarsToColors which seems pretty useful in my case,
but I think I am too stupid to understand how it is working after crawling
through the class library and some posts/threads.

Can somebody support me at converting a scalar value to an RGB color for the
tubes?

Thanks!

Subject: [vtkusers] Python Remote Rendering Issues when Updating Model
Message-ID: <67F41FC4-4EF8-4719-BAD3-C8ACF178B51F@ic.ac.uk>

Hi all,

I am trying to get vtk remote rendering working for a web application and I feel like I?m almost there, but missing something minor.

When running my remote rendering code, I can see my model updating and it works perfectly on the view of the server side model.  However, vtk never opens the web socket link and I am, therefore, unable to view this in a browser window.  It appears to be a result of the vtk callback function which is used to update the model, but I?m not sure how to solve this problem.

Any pointers would be greatly appreciated!

Thanks,
Shruti

Here is my server side code:

vtk_server.py

# import to process args
import sys
import os

# import maths modules
import numpy as np
from scipy.interpolate import interp1d
from scipy import interpolate
from scipy import ndimage
from ReadCSV import readcsv
# from Interpolation import *

# import vtk modules.
import vtk
from vtk.web import protocols
from vtk.web import wslink as vtk_wslink
from wslink import server

from vtkTimerCallback import vtkTimerCallback

# import utility modules
import csv
import time

import argparse

# =============================================================================
# Create custom ServerProtocol class to handle clients requests
# =============================================================================

class _WebCone(vtk_wslink.ServerProtocol):
# Application configuration

Subject: [vtkusers] Wrong coordinates from 2d slices into 3d volume to 2d
Message-ID: <1552994870414-0.post@n5.nabble.com>


dear all
I get the volume [0..80,0.80,0,80] and i cut it into slices and i get the
points in vtk coordinates but when i want to draw the points over the volume
i see the volume is smaller than the 2d slices. 

Should i multiply each x* size of the volume_x / size_x in the 2d slices ?

And the same for y and z?

Thank you

Subject: [vtkusers] Picking point clouds inside vtkBoxWidget
Message-ID: <1553000510121-0.post@n5.nabble.com>

Hello, I have just started experimenting with VTK library. So far in my
project, I have created the following cube structure:

    struct Cube
    {
        Cube(){
            type="unknown";
           
this->detail.center_x=this->detail.center_y=this->detail.center_z=0;
            this->detail.yaw=2;
            this->detail.length=this->detail.width=this->detail.height=1;
        }
        Cube(const double p1[3],const double p2[3],string type_="unknown"){
            type=type_;
            this->detail.center_x=(p1[0]+p2[0])/2;
            this->detail.center_y=(p1[1]+p2[1])/2;
            this->detail.center_z=(p1[2]+p2[2])/2;
            this->detail.yaw=0;
            this->detail.length=p2[0]-p1[0];
            this->detail.width=p2[1]-p1[1];
            this->detail.height=p2[2]-p1[2];
        }
        string type;
        union{
            double data[7];
            struct{
                double center_x;
                double center_y;
                double center_z;
                double length;
                double width;
                double height;
                double yaw;
            } detail;
        };

        string toString(){
            char buffer [200];
            sprintf(buffer,"%s %f %f %f %f %f %f %f",
                   
type.c_str(),data[0],data[1],data[2],data[3],data[4],data[5],data[6]);
            return std::string(buffer);;
         }
    };

When the cube is selected, its vtkBoxWidget gets activated as follow:

    boxWidget = vtkSmartPointer<vtkBoxWidgetRestricted>::New();
    boxWidgetCallback0 = vtkSmartPointer<vtkBoxWidgetCallback0>::New();
    boxWidgetCallback0->setAnno(this);
    
    boxWidget->SetInteractor(interactor);
    double bounds[6]={-1,1,-1,1,-1,1};
    boxWidget->PlaceWidget(bounds);

    vtkSmartPointer<vtkTransform> t=vtkSmartPointer<vtkTransform>::New();
    t->DeepCopy(actor->GetUserTransform());
    boxWidget->SetTransform(t);
    boxWidget->SetHandleSize(0.01);
    boxWidget->GetOutlineProperty()->SetAmbientColor(1.0,0.0,0.0);

    boxWidget->AddObserver( vtkCommand::InteractionEvent, boxWidgetCallback0
);
    boxWidget->On();

In my program I open a point cloud file, where the point clouds can be
viewed in the visalizer and I can add as many cubes on the point clouds as I
can. 

My question is, is there a possible way to pick all the point clouds inside
the selected vtkBoxWidget so I can then remove these points inside the box,
would getPolyData work for this purpose? 

Any help is appreciated :)

Subject: [vtkusers] raycasting initially renders at low resolution
Message-ID: <CALbMNiw9o4DcqE6WDS9_B0L7F=LUzcbqCCN=i5KO=PpPm7=irw@mail.gmail.com>

Hi VTK-experts,
   I'm working on an app for viewing CT scans in 3D or 2D. When I initially
render the CT scan in 3D, the raycast rendering looks great (see the
attached normalResolution.png). However, when I switch from a 2D view
(performed via a vtkImageViewer2) back to the 3D raycast rendering, the
resolution is low (see the attached lowResolution.png). As soon as I
interact with the 3D rendering, the resolution returns to normal.
   Can anyone tell me how to fix this? I have AutoAdjustSampleDistance set
to "off" on the vtkFixedPointVolumeRayCastMapper that I'm using for the
raycasting. I would have thought that this would keep the resolution of the
raycasting constant.
    thank you in advance,
      -Merps

Hello,

Would you mind posting your question to https://discourse.vtk.org?
Community support for VTK is transitioning to that forum, and you are more
likely to get an answer there.

Thanks,
Cory

Subject: [vtkusers] Issues with QVTKOpenGLWidget and VTK8.2
Message-ID: <BYAPR10MB3656F732DE24297357230C00A6400@BYAPR10MB3656.namprd10.prod.outlook.com>

Hi,

We have an application based on Qt and Vtk. It runs well on VTK8.1 However, after upgrading to VTK8.2, we experience problems when we first call vtkRenderer::Render(). This call ultimately ends up calling vtkOpenGLState::CheckState, and this fuction emits a lot of error messages which are listed below.

I understand that the vtkOpenGLState is not initialized properly, but I can't seem to figure out what the proper order of initialization is supposed to be. I am calling QSurfaceFormat::setDefaultFormat() before creating my QApplication object. The render window initialization is pretty straightforward:

     _vtkWidget = new QVTKOpenGLWidget((QWidget *)nullptr);
     _vtkWidget->setEnableHiDPI(true);

   // VTK Renderer
    _renderer = vtkSmartPointer<vtkRenderer>::New();
    _renderer->SetLayer(0);

    _rendererOverlay = vtkSmartPointer<vtkRenderer>::New();
    _rendererOverlay->SetLayer(1);

    // VTK/Qt wedded
    vtkNew<vtkGenericOpenGLRenderWindow> renderWindow;

    _qvtkWidget>SetRenderWindow(renderWindow);
    renderWindow->SetNumberOfLayers(2);
    renderWindow->AddRenderer(_renderer);
    renderWindow->AddRenderer(_rendererOverlay);

The vtkOpenGLState::Initialize function is never called


I have tried switching from QVTKOpenGLWidget to QVTKOpenGLNativeWidget, which fixes the state initialization problems (but I am unable to use it, since it causes problems with line drawing as documented here: https://gitlab.kitware.com/vtk/vtk/issues/17154).

So the code works with 8.1 and also works with QVTKOpenGLNativeWidget.

Can someone help me understand what I am doing wrong with the initialization?

Subject: [vtkusers] mouse coordinates from a 3d volume with wrong y
Message-ID: <CA+fPws34zEJpOuGJHf=BTWWVEgQGmGR-jW5UT06FsQ3CgKdUDA@mail.gmail.com>

Dear all,
I want to get the positions of a volume using the mouse for segmentation.
But the y coordinate is wrong. I only get the x and z fine but the depth
(y) is not correct. I use this code to get the position. Is there any way
to obtain the slice (y position)

thanks

            picker->SetTolerance(0.0005);


            //this->GetDefaultRenderer()->Clear();

            // Pick from this location.
            picker->Pick(pos[0], pos[1], 0, global_renderer);

Does anyone have an example of a vtk chart showing in an MFC dialog?  My code compiles but doesn't show anything.

I tried setting the background color of a blank chart but the control area is just white.

Subject: [vtkusers] How to retrieve cells by Type from a vtkUnstructuredGrid?
Message-ID: <1553095805272-0.post@n5.nabble.com>

Hello,

I have a vtkUnstructuredGrid comprising multiple cell types - hexas, tetras,
trias, quads etc.

I need to process the cells by type so I'm looking for a way to extract the
cells by type. 

I looked at the vtkThresholdFilter but it seems like I first need to have a
cell scalar array to identify the cell types

I'm pursuing the idea of getting an array of cell types either from the
vtkUnstructuredGrid or from a vtkCellArray - but I can't find the API's I
need to accomplish this.

Any/all ideas will be gratefully received.

Thanks,

Doug

Subject: [vtkusers] Get voxel values from vtkNIFTIImageReader
Message-ID: <VI1PR05MB593688EF61BA5EC4CC01C556A65E0@VI1PR05MB5936.eurprd05.prod.outlook.com>

Hi,

I am using the vtkNIFTIImageReader to use Nifti files within VTK (e.g. for creating surfaces using marching cubes).
Now I want to simply get the intensity of a certain voxel (e.g. 4 / 17 / 52). Nevertheless, I always get a value of zero.

vtkSmartPointer<vtkNIFTIImageReader> readerVol = vtkSmartPointer<vtkNIFTIImageReader>::New();
readerVol->SetFileName(image.toStdString().c_str());
readerVol->Update();

vtkSmartPointer<vtkImageData> volume = vtkSmartPointer<vtkImageData>:: New();
volume->DeepCopy(readerVol->GetOutput());

float value = volume->GetScalarComponentAsFloat(4, 17, 52, 0);

I also tried to do it like this: https://vtk.org/Wiki/VTK/Examples/Cxx/ImageData/IterateImageData, but it is the same.

When I load the image into an external Nifti viewer, the viewer shows the expected voxel intensity for the given voxel.

What I am doing wrong?

Thank you very much!
Regards

Hi M.,

It doesn't look like you are doing anything wrong, so the first thing to do
is make sure the reader actually read the image.  You can ask the reader to
print the NIfTI header:

    readerVol->Update();
    readerVol->GetNIFTIHeader()->Print(std::cout);

Likewise, you can print info about the image to make sure the Extent is
correct:

    readerVol->GetOutput()->Print(std::cout);

And you can get the range of values stored in the image to check whether
they're all zero:

    double range[2];
    readerVol->GetOutput()->GetPointData()->GetScalars()->GetRange(range);
    std::cout << range[0] << ", " << range[1] << std::endl;

Hope this helps,
    David

Subject: [vtkusers] reslice using an arbitrary orientation
Message-ID: <1553540899712-0.post@n5.nabble.com>

Dear all

I want to reslice a 3d volume computing the perpendicular
between two points x and y. I compute the
perpendicular berween point 1, point2 in x and y (z is the same for all
points as the 
poins are obtained of one slice)

cut the slice cutting through the perpendicular of those two points.

I attach the code. Is there something wrong

Any help?

Dear all

i update the question i wrote wrong the perpendicular making changes
  double perpendicular[3] = { vt[0],0,vt[1] };

but i see that even i compute the perpendicular what it gives it is not
what i want. What i want is the slice that intersects in this orientation
not to create a new coordinate using this orientation. Any idea?

thanks

Dear all,

I have a question. I want to show 	using vtkResliceImageViewer the slices i
have got from the reslicer
filter. So i append in z the output and i call a fuction to show me the
vtkImageData withh all the slices extracted from the reslicer filter. But my
surprise is that only show one slice. But if i use the same
vtkResliceImageViewer  with the whole volume it works propertly. What can i
do to show the slices obtained form the reslicer in the viewer.

Thanks


vtkImageAppend* append1 = vtkImageAppend::New();
	//Define Stack in Z
	append1->SetAppendAxis(2);

...

		reslice->Update();

Subject: [vtkusers] Why rendering of Paint Filter labelmap is different from
 rendering of background image with ImageSlice?
Message-ID: <1553618406836-0.post@n5.nabble.com>

Hello,

I have adapted PaintWidget example for creating labelmap to original image.
When I have interpolation set on off, I can see that the label map created
with paint widget is rendered in a different way than original image. It
looks like origins are different. 
Why is that? Is it possible to have overlay "aligned" to background image?

Hello VTK community,

This is a reminder that the mailing lists vtkusers at vtk.org and
vtk-developers at vtk.org will be closed to new posts in the near future.
Please post new questions and topics on https://discourse.vtk.org.

You can sign up for the web site using your Google or GitHub accounts if
you prefer, otherwise you can register with a user name and password.

To set up Discourse in mailing list mode, please see:

https://discourse.vtk.org/t/using-discourse-as-a-mailing-list/

The current vtkusers at vtk.org and vtk-developers at vtk.org mailing lists will
accept new posts until the middle of 2019, and the archives from these
lists will remain available after that. However, the bulk of VTK discussion
and community support is now happening on https://discourse.vtk.org/.

See you on discourse.vtk.org!

Subject: [vtkusers] Any way to use GPU to make faster performance?
Message-ID: <1553887844749-0.post@n5.nabble.com>

Hi,

I am using VTK for simplex. When I am using a large data set, I am getting a
runtime error. Is it possible to use GPU to make it faster?
