Subject: [vtkusers] vtkBooleanOperationPolyDataFilter crashes while trying
 to intersect 2 vtkTubeFilter outputs
Message-ID: <1522573935594-0.post@n5.nabble.com>

Each time I am trying vtkBooleanOperationPolyDataFilter on 2 vtkTubeFilter
outputs it crashes.

If I replace vtkBooleanOperationPolyDataFilte  with
vtkLoopBooleanPolyDataFilter, I am getting the following warning and no
results:

If my memory is correct vtkTubeFilter generates cells of type TriangleStrip while boolean filters required Triangle cell.

Try passing the tubes through a vtkTriangleFilter first. A vtkCleanPolydata and a vtkPolydataNormals wouldn?t hurt too.

Thanks for answering my question.
I am already using vtkTriangleFilter and vtkButterflySubdivisionFilter to
get fine triangle cells.
Unfortunately, it didn't help.

I think Boolean mesh operations are the only filters in VTK that are broken - randomly produce somewhat incorrect results and sometimes cause crash. There were attempts in the past to fix them, but the task proved to be too difficult for everybody.

If you clean the inputs and/or slightly dislocate them then you might get correct results. If you need a VTK-based solution that works for any input mesh then you can convert meshes to binary images, perform the Boolean operation on the images, and convert the result to mesh.

Your tubes have many coincident faces. If you shift one of the tubes
in x,y,z you will get results.

Thank you for answering, Bill.
I am trying to split my mesh into parts by cutting it along free lines
defined by user.
These user-defined lines may be and very often would be crisscrossing, so I
need to know what parts cut by lines 1...n are intersecting the line number
n+1 in order to cut them again.
As lines are drawn on the surface of my mesh there are by definition many
coincident faces.
I have tried vtkIntersectionPolydataFilter and both boolean filters to no
avail.
I would be very grateful for any advice.

Subject: [vtkusers] Compiling the scatterplot example without cmake
Message-ID: <4d060469-da98-872d-6a80-98f890034404@gmail.com>

Hi,

I have general question about how to compile code without using cmake. I 
have downloaded the scatterplot example because I wanted start from 
something simple. The cmake type of compilation works and the executable 
provides the plot. However when I try to compile it without cmake I get 
a segmentation fault error. This is how I modified the include list:

#include <vtkVersion.h>
#include <vtkSmartPointer.h>
#include <vtkChartXY.h>
#include <vtkContextScene.h>
#include <vtkContextView.h>
#include <vtkFloatArray.h>
#include <vtkPlotPoints.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>
#include <vtkTable.h>

I added the following lines:

#include <vtkAutoInit.h>

VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkRenderingContextOpenGL);
VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);
VTK_MODULE_INIT(vtkInteractionStyle);

The code compiles like this and the compiler does not complain however 
when I run it then it quits with segmentation fault. My guess (and only 
a guess) that this line causes the trouble:

view->GetInteractor()->Start();

Why is the seg. fault happening?

Thanks

Hi,

Any idea on how to cluster the data by giving different marker to each of the Cluster ID in KMeans Clustering?

I could only get the coordinate (centroid) as a return, but I couldnt get the clusters in group/coloured.


Thank you.

Hi all:

I am using QVTKOpenGLWidget to bridge between Qt and Vtk. However, when I
trying to call vtkRenderWindowInteractor::Render in worker thread, it
always report error like "makeCurrent() error", which seems something wrong
while changing OpenGL context. I have googled my questions and found some
suggestions but none of them could work.

Does anybody know exactly how to render images in worker thread?

Thanks in advance.

 You are wasting your time taking this approach.

You have missing dependencies and, since you are not using CMake, you are
largely on your own sorting these out.

VTK is built using CMake and, by using CMake in your own code base, you
will ensure that all the dependencies will be automatically found for you.

If you don't want to use CMake, then this may
help: VTK/Utilities/Maintenance/WhatModulesVTK.py

Subject: [vtkusers] Large volume render + box/line intersection
Message-ID: <1522740202712-0.post@n5.nabble.com>

Hello everybody,

I am new to vtk so please go easy on me 

I have written some code that creates a volume made of "voxels" - basically
a *glyph3d* with a *cubeSource* as the base element and a *polyData* with
the "voxel" (center) coordinates as the input data for the glyph.

The main point of the code is to compute the intersection of a line with the
above mentioned volume and the length through each voxel - I`m using the
*vtkBox::IntersectWithLine*, so when I`m creating the polyData I`m also
creating a "bounds" array that will contain the bounds of each "voxel".

I`ve gotten satisfactory results with small volumes, but what I need in the
end is to use a 250x250x250 "voxels" volume.

I`ve managed to display about 8mil voxels, although the FPS is terrible...

Should I have taken a different approach to this?
Would the OBBTree (IntersectWithLine) be better suited for this?

Regarding the rendering, I`m getting some strange behavior: the program uses
around 6-7GB (RAM) to generate everything and up to a total of 10-12GB after
the volume has been displayed. This is just for the rendering (8 million
voxels), I`m writing the intersection results in separate files, on the HDD.
After a couple of minutes this drops to a couple of GB and in the end to
just 500MB... is this normal (some sort of garbage collection)?

Thanks!

Hi Hugh

QVTKOpenGLWidget is currently undergoing a complete redesign, the new
version should be avaible shortly.
In any case you can test it beforehand by compiling  a specific
developement branch of VTK, that can be found here:
https://gitlab.kitware.com/vtk/vtk/merge_requests/3745

Best,


Mathieu Westphal

Many thanks Bill for this big effort! Having the text searchable and (hyper-)

I have to jump in and ask: This new class doesn't make it safe to call
Render() from threads other than the UI thread, right? Or does it
change things wrt to threading vs the old QOpenGLWidget?

Just asking so there are no misunderstandings.

Message-ID: <CA+wDR0tHqe+zfM4CmSz-wWzcSQZh_996kOEBbEuYu2A2=PSHrA@mail.gmail.com>

Hello VTK Users,

I am having trouble compiling VTK's OpenVR Module. I am using Visual Studio
15 2017 Win64 compiler on a Windows 10 machine.
I linked include files and the library from the openVR Module:
https://github.com/ValveSoftware/openvr
I also downloaded SDL2, but it was not asked within the configuring process.
The error I get in Visual Studio is the following:
Error C2039 'IsInputFocusCapturedByAnotherProcess': is not a member of
'vr::IVRSystem' Project: vtkRenderingOpenVR
C:\Tools\VTK-8.1.0\Rendering\OpenVR\vtkOpenVRRenderWindow.cxx line 281

What am I doing wrong in the build process? Did I forget to link anything?

Thanks a lot,
Jamil

Take a look at: https://lorensen.github.io/VTKExamples/site/VTKBook/Chapter3/

In this Chapter,

1) Replaced badly converted equations with an admonition.

2) Added an admonition for missing examples.

3) Most importantly, I was able to extract the manually created
figures. The graphics converted just fine, but no text. I added the
text to these figures.

There is still some work to be done on the chapter. Notably recovering
the equations. I'm looking for ways to do this. This effort will
require access to the original Framemaker files, possibly requiring an
export from FrameMaker to a more portable format than .fm files.\

I also converted the Preface and Introduction:

As usual, please reply with comments.

Nah, they (steam/openvr) just changed the API and removed that function.
You can remove it in your copy of VTK or I'll push a patch later today to
do it.

Thanks!

Hi Ken,

thanks alot for the fast answer, it compiles now! I just commented the two
error lines out and removed the bool "bIsInputCapturedByAnotherProcess"
from another if-condition.

Thanks,
Jamil

Subject: [vtkusers] vtkParticleReader and vtkGlyph3D
Message-ID: <CABrYh3qsYbFDN1PPuON7HAQv6229XKZJhTxkue=SuCxMZ1G+Ug@mail.gmail.com>

Hello all:

Can someone help me understand why this code works:

  vtkSmartPointer<vtkGlyph3D> glyph3D = vtkSmartPointer<vtkGlyph3D>::New();
  glyph3D->SetSourceConnection(cubeSource->GetOutputPort());
  glyph3D->SetInputData(polydata);
  glyph3D->Update();

And this does not (nothing displayed)?

  vtkSmartPointer<vtkGlyph3D> glyph3D =  vtkSmartPointer<vtkGlyph3D>::New();
  glyph3D->SetSourceConnection(cubeSource->GetOutputPort());
  glyph3D->SetInputData(reader->GetOutput());
  glyph3D->Update();

The first clip is from
https://www.vtk.org/Wiki/VTK/Examples/Cxx/Filtering/Glyph3D

The 'reader' object is stolen from the ParticleReader example:

  vtkSmartPointer<vtkParticleReader> reader =
vtkSmartPointer<vtkParticleReader>::New();
  reader->SetFileName ( filePath.c_str() );
  reader->SetDataByteOrderToBigEndian();
  reader->Update();

The program compiles, but no data appears. It works fine (data appears) in
the context of the ParticleReader example, where it shows all the data
points. But I want to see them as glyphs, not little squares. I seem to be
misunderstanding something fundamental, but not seeing what it could be.

Many thanks,

 -Tom

On Win 10 build I now get:

When building VTK this did work

-DModule_vtkRenderingVolumeOpenGL=ON

I mean (worked) the rendering was still horrid slow, but it built and ran.

https://blog.kitware.com/volume-rendering-improvements-in-vtk/

states to use:

-DModule_vtkRenderingVolumeOpenGLNew=ON,

though that is circa 2014

https://gitlab.kitware.com/search?utf8=%E2%9C%93&snippets=&scope=&search=vtkRenderingVolumeOpenGL&project_id=13

might lead me to believe if I look at the android section:

  -DModule_vtkTestingCore:BOOL=ON
  -DModule_vtkTestingRendering:BOOL=ON
  -DModule_vtkRenderingVolumeOpenGL2:BOOL=ON


Though I am not compiling for android or iOS.

Is there a way to build the "New" (well post OpenGL fixed pipeline) version
in version 8.0.1?

Tom,

Just make sure that reader->Update(); was called before
glyph3D->SetInputData(reader->GetOutput());
But it would be better to use the connection instead of the dataset
directly.

Hi Sebastien:

Sorry if that was unclear. The third block of code comes first, and
reader->Update() is called before I use its GetOutput().  In situ, it looks
like this:

 ...
  vtkSmartPointer<vtkParticleReader> reader = vtkSmartPointer<
vtkParticleReader>::New();
  reader->SetFileName ( filePath.c_str() );
  reader->SetDataByteOrderToBigEndian();
  reader->Update();

  // Create anything you want here, we will use a cube for the demo.
  vtkSmartPointer<vtkCubeSource> cubeSource =
      vtkSmartPointer<vtkCubeSource>::New();

  vtkSmartPointer<vtkGlyph3D> glyph3D =  vtkSmartPointer<vtkGlyph3D>::New();
  glyph3D->SetSourceConnection(cubeSource->GetOutputPort());
  glyph3D->SetInputData(reader->GetOutput());
  glyph3D->Update();

  ...

I don't think I understand what you mean by the connection instead of the
dataset directly.

Is there a way to peek inside glyph3D and see what it thinks it has?

Thank you,

 -Tom

You can try to see what the GetOutput() contains as my assumption it would
be empty (No points => Number of Points: 0).

reader->GetOutput()->PrintSelf(cout, vtkIndent(2));

What I mean was

glyph3D->SetInputConnection(reader->GetOutputPort());

 This is reader->GetOutput()

vtkPolyData (0x7f8ce050dad0)

  Debug: Off

  Modified Time: 217

  Reference Count: 1

  Registered Events: (none)

  Information: 0x7f8ce050d9b0

  Data Released: False

  Global Release Data: Off

  UpdateTime: 218

  Field Data:

    Debug: Off

    Modified Time: 167

    Reference Count: 1

    Registered Events: (none)

    Number Of Arrays: 0

    Number Of Components: 0

    Number Of Tuples: 0

  Number Of Points: 10229

  Number Of Cells: 10229

It goes on for quite a bit more. As I said, when I feed this to a
vtkPolyDataMapper, it displays and works fine, but I want little spheres,
not little flat rectangles and I thought I could just redirect that into
the vtkGlyph3D object, but I must be misunderstanding something.

Thank you,

 -Tom

Ok as stated here
https://blog.kitware.com/paraview-5-0-0-available-for-download/

and search  VTK_RENDERING_BACKEND which yields the sentence:

"When building from source, simply set the VTK_RENDERING_BACKEND CMake
variable to OpenGL2 to use this new rendering engine."

any thoughts on adding this to

https://www.vtk.org/Wiki/VTK/Building/Windows

which looks to be circa VS 2008

or more generally to:

What you are doing seems correct and the data is valid (it has points).

How do you render the glyph3d filter? Using a polydata mapper? I'm guessing
no issue on that end?

Ideally you should use the glyph mapper instead of the filter. But if
memory is not a big deal, don't worry about it.

Post a small compilable example, please. It is often some unexpected
minor thing that causes the failure.

Thanks,

Bill

"It is often some unexpected minor thing that causes the failure."

I'm certain of that.

Here's the code, mostly pinched straight from the Glyph3D example. (And
I've tried swapping the endianness, just for giggles.) The data is an ASCII
vtk file that you can get from sgouros.com/output_p40.vtk.

Thank you,

 -Tom

Hi,

So that would involve creating a custom array, filling it with the extracted data, adding it to the unstructured grid and setting the active array?

Thank you - that certainly solves my problem. 

However, I felt like there should exist a solution where extracting data to a designated array is not necessary as classes like vtkColorTransferFunction already offer the functionality to set individual vector components. 
This functionality seems to be ignored by the vtkProjectedTetrahedraMapper so I wonder if I missed out on something. 
I would prefer such a solution to adding an array to the unstructured grid because I also want to export the unstructured grid and modifying the original would complicate the export process since those changes need to be reversed.

Kind regards,
Bertram

Hi Bertram,

I have unstructured grid vector plot and each point has xfield, yfield and z field values.You can accomplish what you're looking for by giving the user the option to plot X,Y,Z,XY,XZ,YZ or XYZ components

Depending on user selection you can just compute the magnitude of selected
component(s) and set the scalar values accordingly for contour plot or just use InsertNextTuple3(xfield,yfield, zfield) for vector plot

Regards

Message-ID: <CAM=S0SDFwYadQFBL-pjUSWsD-82gtwPLUbwdH=TLTaL=mu0ErA@mail.gmail.com>

Hello everyone,

I am receiving some errors on cleanup of my application. I am using Python
3.5.4 with PyQt5 and VTK 8.1 (Conda installed). I have a basic GUI with two
widgets used with VTK, each one instantiates a QVTKRenderWindowInteractor,
vtkRenderer and vtkRenderWindow like you'd expect. Here is a simplified
test case I have made: https://pastebin.com/EwuHZBFG. For the test case,
here is the output that is generated:

*destructor*
*SliceWidget_del1*
*SliceWidget_del2*
*SliceWidget_del3*
*SliceWidget_del4*

*SliceWidget_del1*
*SliceWidget_del2*
*ERROR: In ..\Rendering\OpenGL2\vtkWin32OpenGLRenderWindow.cxx, line 227*
*vtkWin32OpenGLRenderWindow (00000258F6471A00): wglMakeCurrent failed in
MakeCurrent(), error: The handle is invalid.*


*ERROR: In ..\Rendering\OpenGL2\vtkWin32OpenGLRenderWindow.cxx, line 87*
*vtkWin32OpenGLRenderWindow (00000258F6471A00): wglMakeCurrent failed in
Clean(), error: 6*

*SliceWidget_del3*
*SliceWidget_del4*

What this indicates is that on vtkRenderWindow.Finalize(), it is failing on
the *SECOND* destructor. So naturally, I removed the second render window
and found it works fine on applications with one render window.

After extensive debugging, I have found that this issue can be resolved if
vtkRenderWindow.Finalize() is called for both windows before the
interactor, renderWindow and renderer are destroyed. At lines 71 and 72 in
the test case if you uncomment them, then the code works fine.

In other words, here is a basic example
*# This WILL work*
*sliceWidget1.Finalize()*
*sliceWidget2.Finalize()*

*delete sliceWidget1 (This will delete interactor, renderer and
renderWindow)*
*delete sliceWidget2 (This will delete interactor, renderer and
renderWindow)*


*# This WILL NOT work*
*delete sliceWidget1 (This will delete interactor, renderer and
renderWindow)*
*sliceWidget1.Finalize()*
*delete sliceWidget2 (This will delete interactor, renderer and
renderWindow)*
*sliceWidget2.Finalize()*

Can anyone offer any assistance on where in VTK this may be causing an
issue? My initial thoughts is that upon destruction of one of the VTK
objects, the context device ID is destroyed and thus cannot be used in the
second Finalize() call. I don't have much familiarity in the VTK source
code, so I was fairly lost in trying to pinpoint the issue.

Thanks,
Addison

vtkVolumeTextureMapper3D has been removed as now we have two VTK mappers
CPU and GPU one. vtkVolumeTextureMapper3D is based on a outdated
technology. It was deprecated I believe and removed in later versions.

Do you need it for any specific reasons?

thanks,

I'm having a go at converting what Bill has done to Latex.

This is because Latex is really good at handling equations etc. Also it is
easy to produce a PDF for publication for those who want a book format.

I'm converting the markdown files that Bill has already done.

Here is my first attempt at the Preface. I think I cal also add a little
image at the top of each chapter.

My Latex is pretty rusty but I will also have a go at Chapter 3 and 6.

Regards
   Andrew

Subject: [vtkusers] vtkObjImporter and vtkPolyDataNormals
Message-ID: <CABrYh3roPE5xQ3_cCN-78NhRv0=MWC3HWZ5kdqq-Ca0YwZe=xg@mail.gmail.com>

Hello all:

I'm looking at the example for the vtkObjImporter class found here:

  https://lorensen.github.io/VTKExamples/site/Cxx/IO/OBJImporter/

There is a mapper created there whose inputs are set to the outputs of a
vtkPolyDataNormals object (just a few lines back from the end). But its
output is never set to anybody's input. Why is that?

Asking because I need to insert a vtkTransformFilter into the mix, and I
don't really see where it should go in order to transform the position of
the imported object.

Thank you,

 -Tom

The mapper is obtained from the actors created by the importer. You
can build a pipeline and connect the last element of the pipeline to
the mappers.

What is your VTK version?
You probably should use SetInputData.

I found a good solution for embedding latex into markdown. I tried a
couple of equations and it works! Now I need to learn how to do math
in Latex.

Hi Bill,
This looks like it will be useful. I'll try it out on the VTKFileFormats
sometime over the weekend. I wasn't happy with what I did there but it
looked sort of OK.

Subject: [vtkusers] VTK 8.1.0 opengl 2 init.... how do I do this now?
Message-ID: <CADsa1k1hJMRmjnzqtOUdsPDgzVqR3J-aukGwRH4+JMgwHgwpfA@mail.gmail.com>

I use to:

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);
//VTK_MODULE_INIT(vtkGPUVolumeRayCastMapper);
//VTK_MODULE_INIT(vtkFixedPointVolumeRayCastMapper);


and at times define

vtkRenderingCore_AUTOINIT="1(vtkRenderingOpenGL)"
vtkRenderingVolume_AUTOINIT=1(vtkRenderingVolumeOpenGL)
vtkRenderingCore=vtkRenderingOpenGL

However in 8.1.0 build I get

(void)" (?vtkRenderingOpenGL_AutoInit_Construct@@YAXXZ) referenced in
function "public: __cdecl
vtkRenderingOpenGL_ModuleInit::vtkRenderingOpenGL_ModuleInit(void)"
(??0vtkRenderingOpenGL_ModuleInit@@QEAA at XZ)

which reminds me of every other time I try and build it when the version
changes.  What is special sauce recipe for 8.1.0 and building with post
opengl 2 (GLSL shader enabled version)


Anyone count the number of threads over the years that discuss the opengl
init in VTK... there is such a sea of posts I am not even going to bother
to fish out what may be the solution somewhere buried in the ether else I
have to get out my heavy duty digital backhoe and realy dig for it.  Sure
I'll find it in some blog post somewhere.

Any one at Kitware want to rethink the opengl design (Build and init
process)?

Part of solution may be to change:

to

VTK_MODULE_INIT(vtkRenderingOpenGL2);

Bill, Andrew, simply brilliant.

I've spot some parts in the Chapters 3 and 6 strawmans that were
already mentioned by you and Todd whose transition has some errors
(links that are missing, missing cross-reference links to VTK classes,
examples or bibliography, etc.).

How can we contribute to fix them? Are you still working on the
transition tools to improve the output, or you want us to manually try
to fix them?

I can help with/do all the Maths in LaTeX Bill. However, if the tool
you found works or the transition will be automatic, I do not see
where to help at this stage. Please, let me know.

Otherwise, it's looking awesome.

As for the LaTeX vs. Markdown/reStrucuredText discussion:

I've contributed with some patches to the ITK SW Guide written in
LaTeX. I guess at the time it was written Markdown and reStrucuredText
were not available, so I think the choice was fair.

Having said that, I admit that the learning curve for LaTeX may be
higher than that for Markdown or reStrucuredText. The latter are
tailored for web navigation, which is most people expect. And times
have changed. I ignore whether Markdown/reStrucuredText support for
tools to have proper printed texts is likely to be improved.

I guess the ITK SW Guide requiring to be compiled (both the examples
to generate the figures and LaTeX itself) is not a downside, since VTK
Cxx examples used in this book need so.

I guess having a first version for both cases (LaTeX and
Markdown/reStrucuredText) is somehow costly at the beginning.
Maintaining/sync'ing them once that is done every time there is a
change may not effortless also. But that may be the price to pay.

The ITK SW Guide keeps being maintained. I ignore whether the ITK
folks at Kitware have considered to transition to Markdown or
reStrucuredText.

Hi All:

Following up on this, can anyone advise me how to get the data out of a
ParticleReader? I think my best option is just to build up data in a
vtkPoints array by hand, as it were. But I can't find a
ParticleReader::GetParticleData method or even anything that looks remotely
like it. I tried converting it to a vtkTable, but that was rejected. The
file is an ASCII vtk file, so I can always read it by hand, but that can't
really be the right way to do this, can it?

Thank you,

 -Tom

Subject: [vtkusers] compiling with vtk
Message-ID: <CABrYh3qq3Xh3u=Eb9AvwBagDivv=M1tFF6xHN8OYKLSfVxzRbA@mail.gmail.com>

Hi All:

I have a CMakeLists.txt file with this in it:

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})

message(STATUS "VTK: ${VTK_LIBRARIES}")
 ...


And a subdirectory CMakeLists.txt file with this:

add_executable(vtkObjViewer vtkObjViewer.cxx)
target_link_libraries(vtkObjViewer PUBLIC MinVR::MinVR
  ${VTK_LIBRARIES}



That produces this output:

-- VTK: vtksys;vtkCommonCore;vtkCommonMath;vtkCommonMisc;...

...

[ 50%] *Linking CXX executable ../bin/vtkObjViewer*

ld: library not found for -lvtksys

clang: *error: *linker command failed with exit code 1 (use -v to see
invocation)

make[2]: *** [bin/vtkObjViewer] Error 1

make[1]: *** [examples/CMakeFiles/vtkObjViewer.dir/all] Error 2

make: *** [all] Error 2


The vtksys library is obviously wtihin the libraries list, right there at
the front, and I've confirmed that libvtksys exists and is in the directory
where I've pointed cmake. Can anyone help me understand what I'm doing
wrong? Or at least what else I should check?

Thank you,

 -Tom

Supposedly you shouldn't need to do any of that and CMake will take care of
it all assuming you link against the right targets (which generally works
for me for my projects).  In one case where that did not seem to work on an
iOS app I added

  vtkRenderingOpenGL2ObjectFactory *of =
vtkRenderingOpenGL2ObjectFactory::New();
  vtkObjectFactory::RegisterFactory(of);

to my source code to pull in and initialize the object factory I needed.

BTW I merged a fix for this into master and tested it against the latest
OpenVR API and it seems to work. So hopefully we are good until they change
something else :-)

"I ignore whether Markdown/reStrucuredText support for
tools to have proper printed texts is likely to be improved."

I have become a big fan of "print to pdf using the Chrome browser" to
get a printed copy of web content these days. It's actually not a bad
way to go if you don't need to refer to page numbers within the text.


And now, this is just my opinion, so take with yet another grain of salt:

The available "writer pool" for LaTeX is far far smaller than that for
markdown. If the math stuff must be in LaTeX, I'd very strongly prefer
to see it as embedded chunks of LaTeX than have the whole thing be in
LaTeX.


Nice work, as usual Bill.


Thanks,
David C.

Awesome thank you :) As there is now a new Vive on the market (HTC Vive
Pro), we are considering getting one. It says on the website that there is
backwards compatibility. Has anyone tried vtk and OpenVR with the new
hardware and can verify that?

More progress.I found a great online tool to generate Latex formulas.
With no previous Latex experience,I was able to generate all of the
equations for Chapter 3. I can embed Latex in the markdown. The
equations are rendered by MathJax.

Here is the online website:
http://www.hostmath.com/

and here is the updated Chapter 3:

Subject: [vtkusers] General Question to VTK in VR
Message-ID: <CA+wDR0uLvV+8HbKdoiYLfUM=Azd2PxugO5s8CF9ZtdprYfkLpQ@mail.gmail.com>

Hello VTK Users,

I have some general questions to the current state of VR in VTK. Please let
me know if this is not the right place to ask questions about that.
According to what I have read (among others "Enhancements to VTK enabling
scientific visualization in immersive environments") there are two
favourized ways of bringing VTK into VR:
- VR-Toolkit embedding --> Using VTK with the OpenVR API (HMDs)
- OpenGL context sharing (VTK Rendering External) --> Using existing
contexts from other (VR-)Toolkits (Multiple devices)

Until now I have only seen single frames being displayed in VR (in VTK as
well as in Paraview), not unsteady state (e.g. in ParaView 5.3, OpenVR
version, I cannot press the play button and send the content to OpenVR, I
can only see one frame on the HMD).
>From what I have seen so far, the VR-Plugin of ParaView does not use any of
the two methods. They are using the library VRPN for interacting but all
the rest is done within ParaView.

My questions are the following:
- Is there anybody who has displayed unsteady states with VTK in VR and if
so what method was used and how was that done?
- Is there any paper or detailled documentation to the OpenGL context
sharing method? I did not find alot to that except from the testing example
"TestGLUTRenderWindow.cxx" which I was not able to build properly until
now. Also, if anyone has experience using FreeVR with VTK OpenGL context
sharing method, I would be very interested in that too.

I hope my questions are appropriate (and not too widespread) and I would be
very happy to be pointed to some current sources, especially concerning
unsteady state simulations with VTK in VR. I would be very happy for anyone
to share their own experiences or some current papers to that topic.

Thanks alot,

Jamil

Hello Tom,

Your code and data work without any problem and display glyphs. The
testing data is attached.
There is some doubt whether the problem always occurs.

Thanks,

At a high level the OpenVR module in VTK definitely supports animations in
VR. We have a demo of 4D pediatric medical data and another of airflow
stream particles. Both run nicely with no issues. So technically there is
no problem with it.

I believe the nightly PV builds for windows now include the OpenVR plugin
and it also supports animations using the OpenVR plugin. This version may
be more recent and capable than the OpenVR specific executable that I
previously posted. I think you send to OpenVR first, and then start playing
the animation. I have tested this, just not in the past month or so.
But....200 fps animations are not really PVs strong suit (never really been
a main use case for it) so you may run into performance issues unless you
are careful.

FWIW PV uses the shared context approach for OpenVR.

The VR (not openVR) plugin for PV is a completely different beast.

Yes! 3D Slicer has an awesome VR viewer. With a single click, the 3D scene appears in your headset and the application remains fully interactive ? you can manipulate objects both on the desktop using keyboard and mouse, and using VR controllers in the VR view. You can also view dynamic content, such as 4D volumes even using volume rendering.

The source code is available here: https://github.com/KitwareMedical/SlicerVirtualReality. You should be able to find all the implementation details there.

To try it: Download a recent Slicer nightly version (https://download.slicer.org), install SlicerVirtualReality extension from Slicer?s extension manager. After you loaded your data you just need to click the VR headset button on the toolbar (?Show scene in virtual reality?).

Limitations: There is a bug in volume rendering that clips the volume at unexpected locations (Kitware is working on a fix, expected to be ready soon). Position of objects that are moved using VR controllers are not yet synchronization back to the scene displayed in the main window (this is the next focus of development).

Subject: [vtkusers] General Question to VTK in VR

Hello VTK Users,

I have some general questions to the current state of VR in VTK. Please let me know if this is not the right place to ask questions about that. According to what I have read (among others "Enhancements to VTK enabling scientific visualization in immersive environments") there are two favourized ways of bringing VTK into VR:
- VR-Toolkit embedding --> Using VTK with the OpenVR API (HMDs)
- OpenGL context sharing (VTK Rendering External) --> Using existing contexts from other (VR-)Toolkits (Multiple devices)

Until now I have only seen single frames being displayed in VR (in VTK as well as in Paraview), not unsteady state (e.g. in ParaView 5.3, OpenVR version, I cannot press the play button and send the content to OpenVR, I can only see one frame on the HMD).
From what I have seen so far, the VR-Plugin of ParaView does not use any of the two methods. They are using the library VRPN for interacting but all the rest is done within ParaView.

My questions are the following:
- Is there anybody who has displayed unsteady states with VTK in VR and if so what method was used and how was that done?
- Is there any paper or detailled documentation to the OpenGL context sharing method? I did not find alot to that except from the testing example
"TestGLUTRenderWindow.cxx" which I was not able to build properly until now. Also, if anyone has experience using FreeVR with VTK OpenGL context sharing method, I would be very interested in that too.

I hope my questions are appropriate (and not too widespread) and I would be very happy to be pointed to some current sources, especially concerning unsteady state simulations with VTK in VR. I would be very happy for anyone to share their own experiences or some current papers to that topic.

Thanks alot,

Jamil

Subject: [vtkusers] Animation with VTU files.
Message-ID: <HE1PR0501MB3578ECBC388A90706E528DC2B7BA0@HE1PR0501MB3578.eurprd05.prod.outlook.com>

Dear VTK Users,

I have a question on animation with VTU file series. I wrote a code which displays particels modeled with sphere
glyphs, where the particle positions and radii are read from VTU files:

    VTK_CREATE(vtkXMLUnstructuredGridReader, particleReader);
    VTK_CREATE(vtkSphereSource, sphere);
    VTK_CREATE(vtkGlyph3D, sphereGlyph);
    VTK_CREATE(vtkVertexGlyphFilter, glyphFilter);
    VTK_CREATE(vtkPolyDataMapper, particleMapper);
    VTK_CREATE(vtkActor, particleActor);

    particleReader->SetFileName( particleName.c_str() );
    particleReader->Update();

    vtkUnstructuredGrid *grid           = particleReader->GetOutput();
    vtkPointData        *pointData      = grid->GetPointData();
    pointData->SetActiveScalars("Radii");

    glyphFilter->SetInputData(grid);
    glyphFilter->Update();

    sphere->SetRadius(1);
    sphereGlyph->SetSourceConnection(sphere->GetOutputPort());
    sphereGlyph->SetInputConnection(glyphFilter->GetOutputPort());

    particleMapper->SetInputConnection(sphereGlyph->GetOutputPort());
    particleMapper->SetScalarModeToUsePointFieldData();
    particleMapper->Update();
    particleActor->SetMapper(particleMapper);

    VTK_CREATE(vtkRenderer, renderer);
    VTK_CREATE(vtkRenderWindow, renderWindow);
    VTK_CREATE(vtkRenderWindowInteractor, renderWindowInteractor);

    renderWindow->AddRenderer(renderer);
    renderWindowInteractor->SetRenderWindow(renderWindow);

    renderer->AddActor(particleActor);
    renderer->SetBackground(.3, .6, .3);

    renderWindow->Render();
    renderWindowInteractor->Start();

I would like to make an animation where the particle postions are updated. Thus I would change the string particleName in the argument of the function particleReader->SetFileName() reading a new VTU file and update the whole procedure with the unstructured grid / 3D glyph / glyp filter obejcts. I try to use vktProgrammableFilter and vtkCallbackCommand to impelment the animation process as I found in the example
https://lorensen.github.io/VTKExamples/site/Cxx/Utilities/DataAnimation/

The example uses an vtkSphereSource as an input for the programmable filter, so the example has essentially the code

VTK_CREATE(vtkSphereSource, sphere);
VTK_CREATE(vtkProgrammableFilter, filter);
filter->SetInputConnection(sphere->GetOutputPort());
filter->SetExecuteMethod(AdjustPoints2, filter);
where the function "AdjustPoints2" updates some point position for the sphere source.

I try to figure out what kind of input can be given to the programmable filter in the case of the VTU files.
If would like to pass the reader itself to the programmable filer, so that it could be updated for each file
and I could make the proper update for the grid and the glyphs too. Then the updating function for the
programmable filter execution method looked like:

void Update(void *filterPointer)
{
    vtkSmartPointer<vtkProgrammableFilter> filter = static_cast<vtkProgrammableFilter*>(filterPointer);

    ...

    GetNewVTUFileName(particeName);
    particleReader->SetFileName( particleName.c_str() );
    particleReader->Update();

    vtkUnstructuredGrid *grid           = particleReader->GetOutput();
    vtkPointData        *pointData      = grid->GetPointData();
    pointData->SetActiveScalars("Radii");

    glyphFilter->SetInputData(grid);
    glyphFilter->Update();

    sphere->SetRadius(1);
    sphereGlyph->SetSourceConnection(sphere->GetOutputPort());
    sphereGlyph->SetInputConnection(glyphFilter->GetOutputPort());

    particleMapper->SetInputConnection(sphereGlyph->GetOutputPort());
    particleMapper->SetScalarModeToUsePointFieldData();
    particleMapper->Update();

}

I am not sure if this is feasible since I do not see how to pass the reader itself to the programmable filter.
Could anyone help me with this problem?

Thank you,
Zoltan

Looks great on my phone, including the mathjax rendered equations (see
attached screenshot).

This will be great material for my morning bus rides to work :)

I also think markdown embedded latex is the way to go, instead of full-out
latex.

Thank you, you are very kind to have taken this time. My original program
does indeed work with your data and your data is the same as mine, but the
data files are in different formats, even though they are both ASCII and
contain the same data. The top of my file looks like this:

# vtk DataFile Version 2.0
particlePositions
ASCII
DATASET POLYDATA
POINTS 5111 float
13.451000 37.225000 0.417060
14.771000 10.352000 17.837000
18.511000 32.313000 12.778000
0.644430 21.956000 50.414000
12.346000 22.660000 50.371000
7.361000 7.991100 45.339000
24.999000 16.144000 27.909000 ...

There are 5,111 data points in this file, followed by a few thousand 1.0's.

The top of the file you sent back to me looks like this, and this one works
fine.

13.451000 37.225000 0.417060 1.0
14.771000 10.352000 17.837000 1.0
18.511000 32.313000 12.778000 1.0
0.644430 21.956000 50.414000 1.0
12.346000 22.660000 50.371000 1.0
7.361000 7.991100 45.339000 1.0
24.999000 16.144000 27.909000 1.0 ...

Both files read without obvious error, but only one of them shows data. Can
anyone explain this to me? Or is there somewhere I should be looking for
errors? (And what did you use to convert it?)

Many thanks,

 -Tom

I'm sure the preceding answers to the question will be more than enough to
satisfy the OP, but there is yet another way, a project called MinVR that
is in alpha, but is meant to be a generic and relatively straightforward
way to convert any old 3D graphics program to VR, and that is compatible
with a wide range of displays, including head-mounted displays like the
Oculus and HTC, caves, desktop VR displays, and regular laptop and desktop
screens. I'm working on vtk examples now to illustrate its use with vtk,
not that I'm all that fluent in that dialect. This is a joint project of
people at UMinn and Brown University, and can be found at github.com/MinVR.

Hi Tom,

At last I can replicate your problem. This may be caused by not
selecting an appropriate reader.

vtkParticleReader can't read output_p40.vtk you upload since the
expected format is something like:
 x, y, z, scalar
It also allows for x\ty\tz\tscalar or x y z scalar. See the
documentation about vtkParticleReader.
https://www.vtk.org/doc/nightly/html/classvtkParticleReader.html#details

The correct way to read output_p40.vtk is to use vtkPolyDataReader
rather than vtkParticleReader.

I hope this will be of some help.
Thanks,

Hi Jamil,

The OpenGL context sharing mechanism as exercised by vtkRenderingExternal
module was used to produce a bunch of examples for rendering VTK in a CAVE
environment. The examples are available as part of VruiVTK
<https://github.com/vruivtk> project on GitHub.

While those examples used VRUI as the VR engine, you could just as easily
swap it out with FreeVR. The general logic used is that VRUI/FreeVR would
create the OpenGL context. In the first display call initialize
ExternalVTKWidget to share the existing context with VTK.

Hope that helps.

Thanks,
Sankhesh

Subject: [vtkusers] multiple charts/plots in one window
Message-ID: <f3639142-1f92-77bc-4850-ad838e2de978@gmail.com>

Hi,

I am trying to get 4 charts (vtkChartXY) into a window (multiple 
contextviews in a window I guess). I have looked at the examples for 
lineplot and scatterplot however if I add a chart2 to view they are 
displayed on the top each other. What is the best way to achieve this?

Thanks!

Hello Zoltan,

Probably it is possible to retrieve the vtkXMLUnstructuredGridReader
object from the object that sets the reader as input connection like
something below:

  sphereGlyph->SetSourceConnection(sphere->GetOutputPort());
  sphereGlyph->SetInputConnection(reader->GetOutputPort());

  // reversely access
  auto reader = vtkXMLUnstructuredGridReader::SafeDownCast(
    sphereGlyph->GetInputConnection(0, 0)->GetProducer());

Here is ReverseAccess example from VTK examples
https://lorensen.github.io/VTKExamples/site/Cxx/Visualization/ReverseAccess/

And I attach a simple code without programmable filter though I'm not
sure if this is a correct usage..

Thanks

Subject: [vtkusers] Fluent hdf5 format
Message-ID: <CAHyF3oiCxFXCbHyyuUT8NB_Q7Bwr+a+yhKYR73524DQgP48ziw@mail.gmail.com>

First, I really don't like fluent, however I don't something better yet.

Second, I found out I can export fluent .Cas and .Dat files in hdf5 format
and I would like to read it into vtk/paraview.
I also discovered xdmf as a nice path to do this, but as fluent is face
based storage vs vtk being cell based, has anyone tried to describe this
kind of  conversion in the xdmf format? Or does someone have a ready made
solution? I have found vtkfluentreader to be relatively slow and only work
for matching .Cas and .Dat files, but I need to read many different .Dat
files.

I have used the ensight gold format in the past but it is restricted to
single precision and gives me incorrect values when do post processing
calculations.

Hi All,

It looks like it is also possible to get a pdf version of the book. There
is still a lot to sort out but here is a first attempt. I can take the
markdown files that Bill is producing and use them which is great.

Note that the hyperlinks (inside and outside the document) seem to work Ok.
I haven't indexed anything yet and obviously the illustrations will need
placing correctly.

Still have to figure out how to get an image at top left of the chapter
heading.

So setting up the environment is ongoing.

Regards
   Andrew

 Hi Todd,
Thanks for your advice. The problem is that I want to render the image in
real-time. The solution suggested in the link you posted is no other than a
repeating timer. Is there some way in Vtk to control the update rate?

How often your worker thread calls back to the main thread is entirely dependent on what your thread is doing. I assume that would be each time it finishes another block of geometry for rendering. Anyway the key point is that the method to update the GUI must be synchronised with the main thread. 
Without some example code of what you're trying to do, it is impossible to make any further recommendations.

Hi Kenichiro,

Thank you very much for your help! It seems to be what I need. Just one question: when I run your code I see the particles in the same position with increasing radii.  Does it mean the radii are different in each VTU file whereas the particle positions are the same. Just to be sure that the particle coordinates were read in the file series correctly.

Thanks,
Zoltan

Hello Zoltan,

Probably it is possible to retrieve the vtkXMLUnstructuredGridReader object from the object that sets the reader as input connection like something below:

  sphereGlyph->SetSourceConnection(sphere->GetOutputPort());
  sphereGlyph->SetInputConnection(reader->GetOutputPort());

  // reversely access
  auto reader = vtkXMLUnstructuredGridReader::SafeDownCast(
    sphereGlyph->GetInputConnection(0, 0)->GetProducer());

Here is ReverseAccess example from VTK examples https://lorensen.github.io/VTKExamples/site/Cxx/Visualization/ReverseAccess/

And I attach a simple code without programmable filter though I'm not sure if this is a correct usage..

Thanks

Hi Zoltan,

I'm sorry my data is not special meaning. It was just used to confirm
whether the data were read correctly.
New attachment contains the particles which positions move a little at
every time steps.

Thanks,

Hi Kenichiro,

Yes , it works indeed. Thank you very much. However, when I use your code with my data series I can see only the content of the first file. After the first update the screen remains empty till the end of the series. I tried to figure out why I get this behavior but the only difference in our VTU files are the number and position of the particles and the presence of more point data fields besides the radii data. If you do not mind I attached my files since I am curious how it works with your executable


Thanks a lot,
Zoltan

Hi Zoltan,

I'm sorry my data is not special meaning. It was just used to confirm whether the data were read correctly.
New attachment contains the particles which positions move a little at every time steps.

Thanks,

Does it mean the radii are different in each VTU file whereas the particle positions are the same. Just to be sure that the particle coordinates were read in the file series correctly.

Message-ID: <CADZJ4hPFePGRu-8bQA6E4YpyiUnkPSRVwMbAkMo7v28SaoFnSw@mail.gmail.com>

Folks,

Chapter 6 is progressing well. I'm refining the conversion workflow.

All equations have been latex'ed using the online editor:
http://www.hostmath.com/

Equations in figures are converted to png using the online tool:
http://latex2png.com/

I compose the hand-drawn figures using OpenOffice Impress. It has a
Math editor when I need to insert some math symbols in a figure.

I'm starting to populate the hand-drawn figures.

Take a look here:
https://lorensen.github.io/VTKExamples/site/VTKBook/Chapter6/

Feedback always welcome.

Bill

BTW: Until this effort, I had never written one-line of Latex. The
online editor did all of the work for me.

You can perform all processing in worker threads in the background. Only rendering must happen in the main thread. Rendering of images is usually quite fast - well below 10ms on an average desktop computer, so it should not be the bottleneck.

Also note that for real-time 2D image processing pipelines, enabling multithreading may make update rate much slower, especially when it interferes with the graphics driver?s threaded optimization. Potential solutions: force single-threading by setting global maximum number of threads to 1, use TBB as SMP backend, or fix the recently found bug in multithreader (https://gitlab.kitware.com/vtk/vtk/issues/17279).

Hi Todd,
Thanks for your advice. The problem is that I want to render the image in real-time. The solution suggested in the link you posted is no other than a repeating timer. Is there some way in Vtk to control the update rate?

Hi Hugh

GUI elements are normally only updated on the main thread, so I suspect you need to synchronize your callback from the worker thread. I'm not familiar with Qt, but it seems to be documented.

Hi all:

I am using QVTKOpenGLWidget to bridge between Qt and Vtk. However, when I trying to call vtkRenderWindowInteractor::Render in worker thread, it always report error like "makeCurrent() error", which seems something wrong while changing OpenGL context. I have googled my questions and found some suggestions but none of them could work.

Does anybody know exactly how to render images in worker thread?

Thanks in advance.

Hi Zoltan,

I carelessly forgot to call SetActiveScalars() in
TimerCallbackFunction of my code.
---
  // re-read all the data from the file
  auto reader = vtkXMLUnstructuredGridReader::SafeDownCast(
    glyph3D->GetInputConnection(0, 0)->GetProducer());
  reader->SetFileName(filename.c_str());
  reader->Update();
  reader->GetOutput()->GetPointData()->SetActiveScalars("Radii");
---
When I am doing it this way, my executable works with your data series.

Subject: [vtkusers] Infinite sea plane - what's the best way?
Message-ID: <CY1PR0201MB1532F2C53CBA1DC6AC0AF8E7ABBE0@CY1PR0201MB1532.namprd02.prod.outlook.com>

So I need to create an infinite textured plane to represent the sea.
vtkPlaneSource seems like the right object, but I can't seem to get any of the examples to display anything.
A colleague tried a while back also but said he could only get it to work with OpenGL not OpenGL2.
Anyone able to offer any ideas?
I've got a rectilinear grid working, but it's not ideal, really need an infinite textured plane.

Using VTK 8.1.0, C++

void CModelView::vtkRenderImageToPlane(const CString& inputFilename, float x, float y, float z)
{
       USES_CONVERSION;
       std::string filename = W2A(inputFilename);

       // Read the image which will be the texture,
       Image_Type imageType = GetImageType(inputFilename);
       vtkAlgorithmOutput* ImageOutput = NULL;
       vtkSmartPointer<vtkPNGReader> pNGReader = NULL;
       vtkSmartPointer<vtkJPEGReader> jPEGReader = NULL;
       vtkSmartPointer<vtkBMPReader> bMPReader = NULL;
       switch (imageType)
       {
              case Image_Type::PNG:
              {
                      pNGReader = vtkSmartPointer<vtkPNGReader>::New();
                      pNGReader->SetFileName(filename.c_str());
                      pNGReader->Update();
                      ImageOutput = pNGReader->GetOutputPort();
              }
              break;
              case Image_Type::JPG:
              {
                      jPEGReader = vtkSmartPointer<vtkJPEGReader>::New();

                      jPEGReader->Update();
                      ImageOutput = jPEGReader->GetOutputPort();
              }
              break;
              case Image_Type::BMP:
              {
                      bMPReader = vtkSmartPointer<vtkBMPReader>::New();

              }
              break;
       }
       if (ImageOutput == NULL || (pNGReader == NULL && jPEGReader == NULL && bMPReader == NULL))
              return;

       // Create a plane
       vtkSmartPointer<vtkPlaneSource> plane = vtkSmartPointer<vtkPlaneSource>::New();
       plane->SetNormal(0.0, 0.0, 1.0);
       plane->SetCenter(0, 0, 0);
       //plane->SetResolution(100, 100);
       //plane->SetPoint1(100000, -100000, 0);
       //plane->SetPoint2(-100000, 100000, 0);

       // Apply the texture
       vtkSmartPointer<vtkTexture> texture = vtkSmartPointer<vtkTexture>::New();
       texture->SetInputConnection(ImageOutput);
       texture->InterpolateOn();

Did you get the plan rendering without a texture first?

Hi Aashish,

I was wondering what is the status of this issue?

So far, we have verified that the GPU ray cast volume rendering in 8.1.0
(and 7.1.1) is wrongly rendered in stereo. The two viewpoints generated are
the same except that they are slightly offset to give the illusion of
stereoscopic rendering. This same problem also appears in ParaView 5.4.1.

Thanks.

Hi Kenichiro,

Yes, you are right. It worked with your data since its point data has only one field and the active scalar could be set for it as a default value. My data series has more fields in point data and it was ambiguous which field is to set to the active scalar by default. Now it works with both the series. Thank you very much again!

Regards,
Zoltan

Hi Zoltan,

I carelessly forgot to call SetActiveScalars() in TimerCallbackFunction of my code.
---
  // re-read all the data from the file
  auto reader = vtkXMLUnstructuredGridReader::SafeDownCast(
    glyph3D->GetInputConnection(0, 0)->GetProducer());
  reader->SetFileName(filename.c_str());
  reader->Update();
  reader->GetOutput()->GetPointData()->SetActiveScalars("Radii");

When I am doing it this way, my executable works with your data series.

Does it mean the radii are different in each VTU file whereas the particle positions are the same. Just to be sure that the particle coordinates were read in the file series correctly.

Subject: [vtkusers] Rendering a Window on Screen with

If you need it embedded into a Qt app you can do it the same basic way the
OpenVR plugin in paraview does it.  I think it relies on you having a
vtk/qt window in your app (already up and displayed) and then using that as
the HelperWindow. SOme snippets of code (and a lot you don;t need) can be
found here

Subject: [vtkusers] vtkOpenGLPolyDataMapper,
 custom shaders and line width property

Wide lines on some systems require a geometry shader. Maybe that is causing
the issue. VTK uses some shader name replacements to handle that there may,
or may not be a geometry shader in the mix which is how it handles wide
lines. Maybe take a look at the default shaders (vert,frag,geom) for both
the normal and wide line case in a running VTK and work from there.

That is odd. OpenGL2 has been the default for a while now and it is tested
nightly on many platforms. Need more information about what is specifically
going wrong to diagnose what is wrong in your setup.

VTK doesn't really have the concept of boundless shapes to my knowledge.

It is very likely you could do this with OpenGL2 and programmable shaders.
The shader(s) would evaluate the plane equation, determine a depth and u/v
coordinate for each fragment and then reject or pass and color the fragment
based on the depth test. vtkOSPRay would have a different implementation.

Probably add it as a mode in the vtkSkybox class. Implementation in
vtkOpenGLSkybox just have to change a small bit of shader logic there to
compute a texture coordinate for a floor as opposed to a skybox or a
photosphere.

Subject: [vtkusers] Missing method for vtkInteractorStyleDrawPolygon?
Message-ID: <CABYSrO9+KKMf67Qfe0hkyDqKpmVFSZU4XfjHf-peY0jwdr-Vpw@mail.gmail.com>

I'm trying to implement vtkInteractorStyleDrawPolygon in Python and I'm
following the test:
https://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Rendering/Core/Testing/Cxx/TestPolygonSelection.cxx

But, vtkInteractorStyleDrawPolygon doesn't have a method for
'GetPolygonPoints' in Python. It's in the header, source and documentation,
but python doesn't know about it. Is it because it returns a vtkVector2i?
I'm using VTK 8.1. Any ideas?

Thanks!

Hi Robby
Yes. vtkVector2i is a template based (generic) class, so it isn't wrapped.

You could add a couple of helper methods to VTKint GetPolygonPointCount();
void GetPolygonPoint(int index, int &x, int &y);

For most of my multiple chart needs, I find vtkChartMatrix to be the 
best option (see Charts/Core/Testing/Cxx/TestChartMatrix.cxx).

Subject: [vtkusers] BoxWidget Bounds
Message-ID: <1523427362130-0.post@n5.nabble.com>

Hello, 
I have a vtkBoxWidget2 and I need to know its dimensions (length, width,
height )

I tried using getBounds()....the results are correct if the box is in its
default orientation

Once the box is rotated the results are incorrect

It turns out that getBounds returns the X, Y, Z coordinates of 2 points....
the lower right corner and the upper left corner of a box that bounds the
object
Once the object is rotated the points don't represent the actual object
anymore...like in the picture 

<http://vtk.1045678.n5.nabble.com/file/t342290/realBounds.png> 

My question is how can I get the real dimensions of the box ??

Hello,
 
I am currently working on an application to take 1 Volume and apply different color maps to different opacity functions in a combined view. Essentially I am taking my data and applying different opacity functions to it in order to bring our different materials within the volume. Ideally I want to create a combination volume with each of these other volumes with different color maps applied to each sub volume in the combination volume. I'm uncertain of how to create a combination volume with a bunch of different color maps inside of it, though I have the different opacity functions and individual color maps working. I'm using VTK 8.0 and QT 5.10.
 
I appreciate any Ideas or guidance anyone has.
 
Thank you for your time,

Hi Mark,

A couple of ways come to mind -

   1. You could create a single vtkImageData with multiple scalar
   components in the array and set
   vtkVolumeProperty::SetIndependentComponents(true). When passing the
   color and opacity functions, you?d have to specify the component the
   respective function belongs to. I am not positive, but I believe some areas
   of the code might be restricting this 4 components. Note that this method
   would work as long as the volumes are not overlapping in physical space.
   2. We recently added support for a multiple overlapping volumes in the
   GPU volume mapper via vtkMultiVolume. See
   TestGPURayCastMultiVolumeOverlapping
   <https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastMultiVolumeOverlapping.cxx>
   for an example.

Hope this helps.

Thanks,
Sankhesh

Thank for the reply, but I only want to fill holes generated by the clipping

triangulate those contours, but it did not work.

Hi Sankhesh,
 
Thanks for your help, I think the vtkMultiVolume is exactly what I need. I'm trying to overlay my volumes on top of each other so I think that first option will not work.

By default charts fill a full view, as pointed out you can try
vtkChartMatrix, or you can borrow some of that code to make the charts
a fixed size. You would then need to manage where they are placed, and
how big they are when the widget they are in resizes. You can have as
many charts as you wish in one widget/context view. The bulk of
vtkChartMatrix just manages resizing when the window size is changed.

Subject: [vtkusers] How to set default scalar value when using
 vtkImageReslice
Message-ID: <1523589808529-0.post@n5.nabble.com>

Dear all,
I am trying to use vtkImageReslice to generate an oblique slice from the
image volume. However, when some part of the output image is outside the
volume, the scalar value of the region is very large, which I want it to be
small as it is the background. I am wondering that is there any function
which I can call to set the default scalar value generated by
vtkImageReslice when it is outside the image volume?
Any help would be appreciated, thanks in advance.

default values are (0, 0, 0, 0) and 0, respectively.

The simplest solution might be just to add multiple viewports to the render window and render a different chart in each.

By default charts fill a full view, as pointed out you can try
vtkChartMatrix, or you can borrow some of that code to make the charts
a fixed size. You would then need to manage where they are placed, and
how big they are when the widget they are in resizes. You can have as
many charts as you wish in one widget/context view. The bulk of
vtkChartMatrix just manages resizing when the window size is changed.

Hi, thanks for your reply! I figured out that the default scalar value is 0.
The reason that I thought the value was large is that it appeared to be much
brighter than other pixels inside the volume. and it turned out to be the
problem of indirectly set window/ level because most of the scalar value of
the pixels inside the volume is much smaller than 0. Again, thanks for your
reply~

I have exactly the same problem as pnt1614.
All these examples work only for meshes with one hole, created by cutting.
What if my polydata already has holes, that I want to keep, but *I want to
close one specific hole only ,
the one, created by cutting?*  I am wrapping my head about this problem for
month, still don't have a good answer.

Ah, good point - there are a good many values for which 0 is a large
number! I'm glad it was an easy fix.

The CT number for air is -1000, so for CT with real-world (i.e. Hounsfield)
data values, it's best to set the background to <= -1000.

Hi,

Is there anyone can give me a hint on how to find the highest point (max value of z coordinate) or lowest point (min value of z coordinate) in a polydata?

I want to mark it with a colour circle to visualize as a keypoint.


Thank you so much.

One way is to apply the elevation filter and then threshold/contour and
what not on that.

Hello,

Is there a zebra shader in VTK ? Many surfacing software such as Rhino, Alias and Fusion360 incorporate this Zebra shader to show the continuity (G0,G1,G2..) of the surface between different patchs:
http://www.bluesmith.co.uk/LW/theoryBuilders/evaluateZebra.htm
https://www.youtube.com/watch?v=NtMybG8Nsfg

This allows a designer to verify that the aesthetics of the blend between two surfaces. See attached pictures zebra.png.

Best regards,

is there any chance you have 64bit version compiled and willing to share ?
I'm loading large files and need 64bit.

visible only on that specific slice. I have done adding and interaction etc
but I am just stuck here. I want to create something like 3D Slicer's
Fiducial module. 

Thank you,

Hi, did you find a solution to this problem? I am also stuck in this part.
Please let me know if you have found a way to add seeds to a specific slice.

3D Slicer is open-source and you are allowed to copy and use any of its source code in your own software without restrictions. So, if you need this feature, then one option is to just copy-paste code.

You can save a lot of software development and maintenance time if you don't redevelop this and similar basic features from scratch. Instead, you can use 3D Slicer as a platform and get all essential data import/export, visualization, analysis features for free and spend your time with working on your own ideas, new algorithms, application-specific user interface and workflow.

Hi,
I am adding seeds in vtkResliceImageViewer using vtkSeedWidget. But seeds
are always visible even when I change the slice. I want to add seeds to

Hi,

I am trying to do what you suggested and started combining the the 
examples of scatterplot.cxx and mutipleviewports.cxx -> see the attached 
Scatterplot2.cxx file for the result. the code does compile and run and 
the window is split into 2 however the charts are missing. I am missing 
the mapper and the actor and I am not sure which one to use for 2D scene 
(with vtkChartXY). Is it necessary to have a mapper and an actor for a 
2D scene?


Thanks

Hi,

I manged to display the plots by using using the renderer of the view 
rather the setting the renderer of the view:

//view2->SetRenderer(leftRenderer);
 ?? leftRenderer = view2->GetRenderer();

The plots are now displayed nex to each other!

Hi Andras,

Thank you for your reply. I could get the highest and lowest coordinates from what you have suggested.

I have another question here.

How can I locate the coordinates by giving a coloured point and visualize them?


...

vtkSmartPointer<vtkPolyData> point =
vtkSmartPointer<vtkPolyData>::New();

vtkSmartPointer<vtkPolyDataReader> reader =
vtkSmartPointer<vtkPolyDataReader>::New();
reader->SetFileName(argv[1]);
reader->Update();
point = reader->GetOutput();

double bounds[6];
point->GetBounds(bounds);

std::cout << "xmin: " << bounds[0] << " "
<< "xmax: " << bounds[1] << std::endl
<< "ymin: " << bounds[2] << " "
<< "ymax: " << bounds[3] << std::endl
<< "zmin: " << bounds[4] << " "
<< "zmax: " << bounds[5] << std::endl;

vtkSmartPointer<vtkPolyDataMapper> Mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
Mapper->SetInputConnection(reader->GetOutputPort());
Mapper->ScalarVisibilityOff();
Mapper->Update();

vtkSmartPointer<vtkActor> Actor = vtkSmartPointer<vtkActor>::New();
Actor->SetMapper(Mapper);
Actor->GetProperty()->SetPointSize(10);
Actor->GetProperty()->SetColor(1, 0, 1);


Thank you.

Regards,
Polly

Hi,

Is there anyone can give me a hint on how to find the highest point (max value of z coordinate) or lowest point (min value of z coordinate) in a polydata?

I want to mark it with a colour circle to visualize as a keypoint.



Thank you so much.

There is not currently.

In principle we could do that with a glsl fragment shader applied to the
polydatamapper.

You could also approximate with vtkFunctionParser (paraview's Calculator
filter) and an indexed colormap.

Expression of 5+floor(Normals_Y*5) gives you 10 stripes for the Y component
of the normal.

Hi everyone,

Subject: [vtkusers] Background pixel blending in VTK (2D)
Message-ID: <CA+0LVXovWuqswMSYRbBEDxoz_Lv5f73W_0bif6QVKp1fGiVcoQ@mail.gmail.com>

Hi all -

My company is using VTK to render overlaid DICOM images to a screen.
All of the images in question are single channel intensity mapped
images encoded in a ushort buffer.

Quick overview of how data is built:
- vtkImageReslice is hooked into vtkImageMapToWindowLevelColors object.
- We add a custom lookup table to the window/level colors object.
- We connect the w/l colors object to a vtkImageMapper.
- We connect the image mapper to a Actor2D.
- We then use a vtkImageBlend class and set input connections to two
channels from the Actor2D generated in the above steps.

For each Actor2D object rendered to the screen, we can control default
values of pixels on the screen by accessing values within the lookup
table.  However, for pixels outside the extent of the data being
drawn, the value appears to always be (0,0,0,1).

We run into issues when considering blending of two images.  We need
the background image (if larger than the overlay image) to be present
outside the extents of the overlay image.

I see / have tried various API which seem like they should work - ie:
vtkImageReslice::SetBackgroundColor, setting default value in lookup
table, reimplementing the vtkImageBlend class to attempt to access
these background pixels.

One strange behavior I've noticed, is in the 'SetBackgroundColor(...)'
function on the reslicer, a value of (x, 0, 0, 0) sets the intensity
value of the background pixels - i can achieve a white background if i
set 'x' to be the highest value in our lookup table.  However, the BG
channels remain 0 and A remains 1 even if i specify 0 in the function.
I would assume this is because the DICOM image is a single channel
image, and VTK is generating the background with the same format ..?

I am wondering if anyone has seen/experienced this before, or, knows
how to work around this kind of issue.

thanks

Hi Kyle,

The vtkImageBlend class requires the images to have identical sampling.
It's possible to get it to overlay an image that is smaller than the base
image, but to do so you need the overlay image to have an "Extent" that
starts at a value greater than zero.  The Extent of an image can be shifted
around with the vtkImageChangeInformation filter.  All in all, it is a huge
hassle, and sometimes it's easier to use vtkImageReslice to resample the
overlay to match the base image.

For all DICOM-viewer apps that I've written recently, I've taken a totally
different approach, and used the VTK image rendering classes that I
contributed a few years ago:
https://www.vtk.org/Wiki/VTK/Image_Rendering_Classes

Some examples are here (they're not great examples, but they exist):
https://gitlab.kitware.com/vtk/vtk/tree/master/Rendering/Image/Testing/Cxx
https://github.com/dgobbi/vtk-dicom/blob/master/Examples/TestDICOMDisplay.cxx

If you don't want to go that far, you might consider using the
vtkImageResliceToColors class to resolve the background issue.
This is a subclass of vtkImageReslice that has a SetLookupTable() method.
It combines reslicing and color mapping into a single operation, so that
when you call SetBackgroundColor() you set the actual RGBA color
directly.

If all your axes are set to vtkAxis::AUTO, then you can simply call vtkChartXY::RecalculatePlotBounds().

If you have manually set axes then you can take this method in 3D Slicer's plot view class: https://github.com/Slicer/Slicer/blob/66b152bc35e1f84eafcacd8050300687fa377229/Libs/MRML/Widgets/qMRMLPlotView.cxx#L458-L600

It would probably make sense to integrate this auto-fit feature into VTK.

Subject: [vtkusers] Storing pointers to pipeline objects.
Message-ID: <1523963236330-0.post@n5.nabble.com>

Hi vtkUsers,

After constructing the VTK pipeline and loading some vtkImageData to be
displayed, due to some user request, we may need to access parts of the
pipeline in order to change some properties in an object. For example, lets
say that the user changes the colours of the lookup table used to display
the dataset. This means that the class handling the pipeline needs to store
pointers or references to at least some objects of the pipeline. 

My question is: Is there some best practice or standard way in VTK for
accessing the objects of the pipeline, or do we simply need to store them in
a standard C++ container?

At the moment, I am simply collecting the objects in a struct and storing
them in a C++ container which is member of the class handling the pipeline.
I have included below a sample of what I am doing at the moment. Is there a
better way of doing this?

Thanks,
Panos

===============================================
class QuadView
{
private:
	struct PipelineObjects2D
	{
		vtkSmartPointer<vtkImageStack> imageStack;
		vtkSmartPointer<vtkRenderer> renderer;
		vtkSmartPointer<vtkGenericOpenGLRenderWindow> renderWindow;
	};

	struct ImageDataStruct
	{
		vtkSmartPointer<vtkImageData> imageData;
		vtkSmartPointer<vtkLookupTable> lookupTable;
		std::unordered_map<IQuadViewUI::ViewKey,
vtkSmartPointer&lt;vtkImageResliceMapper>> 
			resliceMapperContainer;
		std::unordered_map<IQuadViewUI::ViewKey,
vtkSmartPointer&lt;vtkImageSlice>> 
			imageSliceContainer;
	};

	std::map<unsigned long /*image UID*/, ImageDataStruct> 
		m_ImageDataContainer;
	std::unordered_map<IQuadViewUI::ViewKey, PipelineObjects2D> 
		m_PipelineObject2DContainer;

public:

	// more code
};

That is a perfectly acceptable and typical way to access objects in the
pipeline.

Hi Andras,
   Thanks for the tip, by default I have the axes set to AUTO and calling recalculate on the chart does the trick. Note: RecalculatePlotBounds is protected so the function I?m running with is RecalculateBounds.

Subject: [vtkusers] Interactor mouse events without disable rotation
 vtkActors
Message-ID: <1524008015351-0.post@n5.nabble.com>

This code is a selector actor. Once one actor is selected it prints the high
of the respective selected actor. the problem is that the rotation and
dragging is disable in the interactor and I want to include it.


*// Handle mouse events
class MouseInteractorStyle5 : public vtkInteractorStyleTrackballActor
{
    public:
    static MouseInteractorStyle5* New();
    vtkTypeMacro(MouseInteractorStyle5, vtkInteractorStyleTrackballActor);

    virtual void OnLeftButtonDown()
    {
        // Forward events
        vtkInteractorStyleTrackballActor::OnLeftButtonDown();

        for (auto it = actors.begin(); it != actors.end(); ++it)
        {
            if(this->InteractionProp == (*it))
            {
                std::cout << "Actor high: " <<
(*it)->GetMapper()->GetInput()->GetPoint(0)[2] << std::endl;
            }
        }

    }
    std::vector<vtkSmartPointer&lt;vtkActor>> actors;
};

vtkStandardNewMacro(MouseInteractorStyle5);

void actorsMouseInteractor(const std::vector<vtkSmartPointer&lt;vtkActor>> &
actors)
{
    // A renderer and render window
    vtkSmartPointer<vtkRenderer> renderer =
      vtkSmartPointer<vtkRenderer>::New();
    vtkSmartPointer<vtkRenderWindow> renderWindow =
      vtkSmartPointer<vtkRenderWindow>::New();
    renderWindow->AddRenderer(renderer);


    // An interactor
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
      vtkSmartPointer<vtkRenderWindowInteractor>::New();
    renderWindowInteractor->SetRenderWindow(renderWindow);

    // Set the custom stype to use for interaction.
    vtkSmartPointer<MouseInteractorStyle5> style =
        vtkSmartPointer<MouseInteractorStyle5>::New();
    style->SetDefaultRenderer(renderer);
    style->actors = actors;

    renderWindowInteractor->SetInteractorStyle(style);

    renderer->AddActor(getPlatformActor());
    for (auto it = actors.begin(); it != actors.end(); ++it)
    {
        renderer->AddActor(*it);
    }
    renderer->SetBackground(.1, .2, .4);
    renderWindow->Render();
    renderWindow->SetSize(renderWindow->GetScreenSize());
    renderWindowInteractor->Start();
}*

the output is for example the position in Z:

Actor high: 1.800

Subject: [vtkusers] How to combine two polys and do a clipping on the merged
 poly?
Message-ID: <1524014979026-0.post@n5.nabble.com>

I want to append 2 polys (A and B) and then use a contour to perform a
clipping on the merged poly. To do that, I generate a quad connecting A with
B and use vtkAppendPolyData to make a merged poly. After that, I use a
contour to do a clipping on the merged poly using vtkClipPolyData but there
is something wrong. Instead of the merged poly with hole, the result is one
of two original polys (A or B) with a hole.

Is there any document explaining how vtkAppendPolyData and vtkClipPolyData
work?. I also tried to check the connectivity of the merged poly using
vtkConnectivityFilter but it seems that A and B are still separated.

Is there anyone experienced this problem? Please, help me.

Hi Aashish,

I'm not sure what specific reason(s) that Brian Davis would want the
vtkVolumeTextureMapper3D back; we want it back too.

For our case, it is because the new CPU/GPU ray cast volume mapper is not
working correctly when depth peeling is enabled (for multiple volumes) and
also when rendering the scene in stereo (left and right images are the
same). I think it is good to have a backup when the only volume mapper
doesn't work.

Subject: [vtkusers] Lattice structures with VTK
Message-ID: <000601d3d6eb$af17d670$0d478350$@gmx.de>

Hi all, 

 

I am currently trying to fill a surface mesh with some volume. Therefore,
the volume should consist of kind of a lattice structure (for example, the
lattice structure could be made of cubes, hexahedra or dodecahedrons.). Is
it possible to generate lattice structures with VTK?

 

Any help would be appreciated!

 

Best regards

Maximilian

Maximillian,

You could create a cubic lattice structure without too much work. See this
example:

https://lorensen.github.io/VTKExamples/site/Cxx/PolyData/PolyDataToImageData/

You can add a vtkThreshold to extract just the portions of the image data
falling inside your original surface.

HTH,
Cory

If there are errors in the current GPU volume mapper then they certainly have to be fixed, but I would rather have only one GPU volume mapper in VTK, which works well. If there were different variants then developers attention might be divided between them and developers may be distracted by users asking help for unsupported classes.

Until error in the current GPU volume mapper is fixed, you can build the old mapper as part of your application or keep using an earlier VTK version.

Chris,

The issue with depth peeling should have been fixed now (try the latest
master). As far as the stereo is concerned. that is puzzling. Can you tell
us more about the stereo problem (apologies if you have sent it already).
In the past we used volume rendering in CAVE and in HMD using OpenVR and
they both seems to be working fine.

thanks,

that was the core idea.. we had too many mappers and it was hard to
maintain / update and there was lot of overlap in features. we should fix
the issues instead.

Unfortunately, I have not produced a 64-bit build this time, and most 
likely will not get to it in a reasonable amount of time.  Perhaps contact 
one of the github members from the issue list, as I know a few of them 
successfully built it. 
  
 I did produce a 64-bit build of v6.2 before, and had no issues doing so, 
except for the step where Activiz packages the runtime redist dependencies. 
 You'll have to fix the CMakeLists.txt file.  And also inspect your system 
CMake modules if using CMake v3.8 or newer. 
  
 I finished a new build of 32bit VTK-7.1.1 with the latest version of HDF5 
in the past couple days. And also rebuilt Activiz against the new VTK.  In 
doing I updated CMake to the v3.10 and there are now a number of errors in 
the CMake Modules for Intel C++ x86 vs x64.  So I would keep an eye on 
those areas.  There maybe other issues lurking about with Release vs Debug 
and x86 vs x64.
  
 And for other users, who had wondered about building the Documentation.  I 
tested the doxygen generation all the way through to Activiz, and it 
appears to work fine.  Requires Perl, graphviz dot, MiTex and HTML Help 
Workshop.  There's an issue with the latest MiTex ghost script, where 
you'll need to link mgs.exe to gswin32c.exe since Doxygen does not appear 
to have a variable to control the Ghostscript binary.  Live and learn,  
that cost we a lot of wasted time to figure out.

Hi Mark, I tried unsuccessfully to compile ActiViz 7.1 and found your 
post,
is there any chance you have 64bit version compiled and willing to share ?
I'm loading large files and need 64bit.

Thanks

Hi Andras & Aashish,

Thanks for explaining the issue. I have a better understanding of the
problems you guys are facing now. Thanks also for fixing the two previous
issues I mentioned. I downloaded the latest master from GitHub and verified
that the bugs are fixed.

Speaking of problems, I hope I can tag on to this thread to sound out two of
the problems we are facing now with the GPU ray cast volume renderer:

1. The first is the incorrect stereo rendering as mentioned before. The two
viewpoints generated are
the same except that they are slightly offset to give the illusion of
stereoscopic rendering. This same problem also appears in ParaView 5.4.1.
This problem only seem to affect ray cast volume rendering and not the
polygonal meshes. The horizontal left-right split viewports shows this very
clearly:

<http://vtk.1045678.n5.nabble.com/file/t342340/Split_Viewports.png> 

We suspect that while rendering the ray cast volumes, the same
viewpoint/perspective matrix was used in both the left and right views.


2. The second problem we encounter is that ray cast volume renderer doesn't
seem to work well when volume depth peeling is activated. I can't explain it
very well, but it seems to us that the depth peeling of ray cast volumes
doesn't seem to be depth correct. The rendering looks better than it is
without depth peeling but at certain angles, it feels as if the depth
peeling has no effect at all. I have attached the following images to help
explain what we are seeing:

<http://vtk.1045678.n5.nabble.com/file/t342340/Without_Depth_Peeling_0.png> 
This image shows two volumes (MRI is grey and CT is yellowish) rendered
without depth peeling. The CT is almost fully occluded.

<http://vtk.1045678.n5.nabble.com/file/t342340/With_Depth_Peeling_1.png> 
The next image shows the same two volumes rendered with depth peeling
activated. As you can see, the CT (yellowish) is smaller than the MRI (grey)
and the CT is almost fully enclosed within the MRI.

The following series of images shows the rendering effect with depth peeling
activated, as viewed from different angles. The CT should be
partially/mostly occluded by the MRI because it is a physically smaller
volume that is located/enclosed within the MRI itself. But as the series of
images shows, it looks as if the CT is floating outside of the MRI or that
the depth peeling is deactivated (it is activated, we checked).

<http://vtk.1045678.n5.nabble.com/file/t342340/With_Depth_Peeling_11.png> 

We wonder what could be the problem.

Thank you so much!

Not a problem Mark, just wondering, I'm using VTK 6.3 and having some issues
with slicing through polyhedron cells, and wondered if that is fixed in some
later versions.
Thanks for you response.

Subject: [vtkusers] Homebrew and VTK: missing cmake options for QVTKWidget
Message-ID: <1524183011715-0.post@n5.nabble.com>

I am working on a piece of software I want to distribute using Homebrew. My
program features a GUI built around a QVTKWidget. 

After a lot of trial and error, I think that the cmake flags I need to set
up the VTK install to work with the QVTK Widgtet are 
*
 -G "Unix Makefiles" -DVTK_USE_QVTK:BOOL=ON -DVTK_USE_GUISUPPORT:BOOL=ON 
-DVTK_Group_Qt:BOOL=ON -DModule_vtkIOExportOpenGL2:BOOL=ON
-DVTK_USE_CXX11_FEATURES:BOOL=ON -DVTK_RENDERING_BACKEND:STRING=OpenGL2 
*
However, the VTK formula currently on tap does not allow these options to be
set. Editing the formula with brew edit is not really an option since each
end user would have to fix it too. 

Is there another way to tell VTK to be built with these flags? If not, is is
possible to add a -with-qvtk option to the formula?

You can use a smart pointer referring to the assembly's matrix. In that way,
you can access to the assembly's matrix after transformation.


vtkSmartPointer<vtkMatrix4x4> m = vtkSmartPointer<vtkMatrix4x4>::New();
m = your_assembly->GetMatrix();

Hi,

Which tap/bottle do you use?
The tap - robotlocomotion/director
<https://github.com/RobotLocomotion/homebrew-director/blob/e23d3af8cd901dcbf334939118e394b1419dae40/Formula/vtk%408.1.rb>
has those configurable options.

Hope that helps!

Hi, Although this is a pretty old thread, I have a followup question on this
one.The debug messages are disabled by default. I thought that I can enable
output using the DebugOn() option. However, the following does not work for
me:I would expect to see a message "SphereSource Executing piece index xx of
yy pieces". (See  here
<https://github.com/Kitware/VTK/blob/c24799a287785046bdd82c3f9d165034d7ab9241/Filters/Sources/vtkSphereSource.cxx#L118> 
.)So how to enable the output on console? I am working in Python.Thanks for
any hints.Norman

Message-ID: <CAM5z2s1sGeM9vQLJ9jbCKd7g1PJ1oL0ONbPQ55wiFk9rTJY-kw@mail.gmail.com>

Hello,


I have an easy question, I think.


I have hundreds of points in the 3D space. I need to visualize each of
these points by a small 2D square, which I implemented. Therefore I have
now hundreds of these small squares in the 3D space. However the issue is
as follows:

When I rotate the scene, while all the squares are naturally moving in
respect to the camera, I want all of the squares keep their orientation
towards the camera and still be constantly facing the camera. I know if I
use vtkFollower I could do this, but not sure how to do it for these MANY
squares in the scene. My pipeline is as follows => All my points are stored
in one single vtkPolydata and I have assigned a vtkSourcePlane to each of
these points using vtkGlyph3D.


Thanks for any feedback.

Subject: [vtkusers] Visualizing HSV color information from a 3D medical
 dataset
Message-ID: <CAHFO-ccTrn9Z+c=rQUTCTqWLkhLAbCaY=_w_rOCJwM-xJx7-Vw@mail.gmail.com>

Hello vtk-users,

I want to visualize a medical dataset using the HSV model color. I found
this great VTK example that works very well
https://lorensen.github.io/VTKExamples/site/Python/VisualizationAlgorithms/ImageGradient/

However, this example use the vtkImageViewer class and the output is only
one slice of the dataset. Anyone knows what mapper could be used to
visualize the same  output but in a 3D way?

Any help provided for this would be greatly appreciated!

Here the code of the example:

import vtk

def main():
    fileName = get_program_parameters()
    colors = vtk.vtkNamedColors()

    # Read the CT data of the human head.
    reader = vtk.vtkMetaImageReader()
    reader.SetFileName(fileName)
    reader.Update()

    cast = vtk.vtkImageCast()
    cast.SetInputConnection(reader.GetOutputPort())
    cast.SetOutputScalarTypeToFloat()

    # Magnify the image.
    magnify = vtk.vtkImageMagnify()
    magnify.SetInputConnection(cast.GetOutputPort())
    magnify.SetMagnificationFactors(2, 2, 1)
    magnify.InterpolateOn()

    # Smooth the data.
    # Remove high frequency artifacts due to linear interpolation.
    smooth = vtk.vtkImageGaussianSmooth()
    smooth.SetInputConnection(magnify.GetOutputPort())
    smooth.SetDimensionality(2)
    smooth.SetStandardDeviations(1.5, 1.5, 0.0)
    smooth.SetRadiusFactors(2.01, 2.01, 0.0)

    # Compute the 2D gradient.
    gradient = vtk.vtkImageGradient()
    gradient.SetInputConnection(smooth.GetOutputPort())
    gradient.SetDimensionality(2)

    # Convert the data to polar coordinates.
    # The image magnitude is mapped into saturation value,
    # whilst the gradient direction is mapped into hue value.
    polar = vtk.vtkImageEuclideanToPolar()
    polar.SetInputConnection(gradient.GetOutputPort())
    polar.SetThetaMaximum(255.0)

    # Add a third component to the data.
    # This is needed since the gradient filter only generates two
components,
    #  and we need three components to represent color.
    pad = vtk.vtkImageConstantPad()
    pad.SetInputConnection(polar.GetOutputPort())
    pad.SetOutputNumberOfScalarComponents(3)
    pad.SetConstant(200.0)

    # At this point we have Hue, Value, Saturation.
    # Permute components so saturation will be constant.
    # Re-arrange components into HSV order.
    permute = vtk.vtkImageExtractComponents()
    permute.SetInputConnection(pad.GetOutputPort())
    permute.SetComponents(0, 2, 1)

    # Convert back into RGB values.
    rgb = vtk.vtkImageHSVToRGB()
    rgb.SetInputConnection(permute.GetOutputPort())
    rgb.SetMaximum(255.0)

    # Set up a viewer for the image.
    # Note that vtkImageViewer and vtkImageViewer2 are convenience wrappers
around
    # vtkActor2D, vtkImageMapper, vtkRenderer, and vtkRenderWindow.
    # So all that needs to be supplied is the interactor.
    viewer = vtk.vtkImageViewer()
    viewer.SetInputConnection(rgb.GetOutputPort())
    viewer.SetZSlice(22)
    viewer.SetColorWindow(255.0)
    viewer.SetColorLevel(127.0)
    viewer.GetRenderWindow().SetSize(512, 512)
    viewer.GetRenderer().SetBackground(colors.GetColor3d("Silver"))

    # Create the RenderWindowInteractor.
    iren = vtk.vtkRenderWindowInteractor()
    viewer.SetupInteractor(iren)
    viewer.Render()

    iren.Initialize()
    iren.Start()

Subject: [vtkusers] vtkOBBTree - Some OBBs contain too much cells
Message-ID: <1524481727486-0.post@n5.nabble.com>

Hello,

I want to test 2 OBB-trees for collisions, generated from STL-files. When
running "IntersectWithOBBTree", most of the leaf node OBBs contain 2 Cells.
("SetNumberOfCellsPerNode(2)")

But for some reason many OBBs contain far more than 100 and some even more
than 1000 cells..
Any Ideas what could cause this Problem?

best regard
Jonas

Message-ID: <3c058693e8ce47b9ada7995851fe7d70@diamond.ac.uk>

Hi,
I would like to have a Python script to render several volume images (tomography data)  on a headless machine. I could not find any advice more recent than 2011 , is this something that just isn't configured in the Python as installed from existing packages? How do I tell?
If it's not in the python , what needs to be done, at the time of prior questions it seemed to be a compile-time option of the VTK library, is that still the case, Any exaples on line that are for the current release ? 
Thanks
Robert

Hi,

You seem to be replying to an old thread, but I don't see the rest of the
conversation.  Since others are probably in the same position, can you give
more details about the problem you are seeing?  We won't be able to help
you unless we know what the problem is.

Thank you,
Shawn

I tried to get the data from the actors using the vtkMatrix4x4 after the
transform  but the matrix doesn't change after the transformation. I am not
sure if i am accessing the matrix in the incorrect way or incorrect
location. I had attached sample working code with which I had tested.

Hi Sam,

While you could use the vtkFollower approach, a better performing approach
would be using the vtkPointGaussianMapper
<https://www.vtk.org/doc/nightly/html/classvtkPointGaussianMapper.html>.
See the ParaView blog post
<https://blog.kitware.com/paraview-5-introducing-the-point-gaussian-representation/>
for examples.
*Note:* You would have to write your own shader preset to render 2D
squares.

Hope that helps,
Sankhesh

Hello,

I'm experimenting with using vtkMultiVolume to add proper multi-volume rendering support into 3D Slicer. My main question is the reason behind this actor not supporting shading, as apparent when used, but also mentioned in the corresponding test:
https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastMultiVolumeOverlapping.cxx#L229
Is this a technical limitation that would be very hard to overcome, or is it something simpler? I'm asking this because for this actor to be really used for volume rendering, shading would be necessary.

Thank you,
Csaba

Subject: [vtkusers] VTK Textbook Efforts Update
Message-ID: <CADZJ4hO4VDPrqipwXBG6hkk+z+52qmMChSL0Pd5WgpiL5X2Ydw@mail.gmail.com>

Folks,

We are pleased to provide an update on efforts to update the online
resources for the fourth edition of the  VTK textbook

There are 3 coordinated efforts ongoing each with a different goal.
Currently, none of the efforts will rewrite sections of the fourth
edition. These are the first steps to a possible fifth edition, but
that effort will require significant resources.

1) The printed and free online PDF of the VTK textbook is the gold
standard for this edition. The online PDF is a low-resolution version
that exhibits some difficulty converting equations. It is available as
one, downloadable PDF with no active links. FrameMaker produces the
PDF  from FrameMaker files capable of producing different PDF
resolutions. Editing the FrameMaker files requires a license from
Adobe. It is unlikely the VTK community will have access to these
proprietary files. Major contributors include Will Schroeder and other
Kitware employees. See: https://www.vtk.org/vtk-textbook/

2)  A VTK latex version of the VTK textbook is a work-in-progress
effort. The goal is to produce a Latex version populated with links to
figures, references, equations, examples, etc. The PDF version is
downloadable as a single file.  The figures that exist as VTK Examples
are linked to the nightly output of the regression testing. Once this
work is stable, the user community will be able to push merge requests
to fix problems with the Latex. The major contributor is Andrew
Maclean. You can follow the progress here:
https://lorensen.github.io/VTKExamples/site/VTKBookLaTex/VTKTextBook/

3) A markdown version of the VTK textbook is also a work-in-progress.
The goal is to produce an interactive, platform friendly version of
the book. The entire text is available on as a Chapter by Chapter
website. The figures that exist as VTK Examples are linked to the
nightly output of the regression testing. Once this work is stable,
the user community will be able to push merge requests to fix problems
with the markdown. The major contributors are Bill Lorensen and
Bernhard Meehan. Bernhard has produced Latex for all 100 equations in
the text.  You can follow the progress here:
https://lorensen.github.io/VTKExamples/site/VTKBook/Chapter1/  and
other chapters.

When the Latex and Markdown versions are more complete, we will ask
the user community to help proofread the new versions.

Hi Csaba,

I don?t believe there is a technical limitation. It was merely that the
original effort for adding multiple overlapping volumes support was focused
on selected features. I am not aware of current efforts/funding to add
support for additional features like shading, different blend modes, etc.

Thanks,
Sankhesh

Subject: [vtkusers] Visualizing a surface
Message-ID: <1524570513469-0.post@n5.nabble.com>

Dear all, 

I have a set of points (around 0.5 million) and I want to visualize these as
a surface/volume. I am programming in c++ and using vtk 8.0
I have extracted the surface points of the dataset to reduce the size.

The points show an arbitrary timestep of a dambreak. 
I have tried the following approaches: 

VTKExtractSurface; Problem: The wave is not shown accurately. I have tried
increasing the samplesize for the normals,   Decreasing the radius for the
calculation of the distances and smoothing the surface. The Result was not
satisfactory 
(https://lorensen.github.io/VTKExamples/site/Cxx/Points/ExtractSurface/)

Delaunay3D; Problem: Mainly useable for convex shapes and the triangle
visualization is not nice for a fluid, further problem: Alpha value needs to
be adjusted for each simulation 

Marching Cubes; Problem: I can't get it to work, I have basically copied
every step from the tutorial:
https://lorensen.github.io/VTKExamples/site/Cxx/Modelling/MarchingCubes/
I can't understand where i went wrong there

GaussianSplatter; Problem: The Points(spheres) are visible, this means it is
not a surface, but spheres  test2.xyz
<http://vtk.1045678.n5.nabble.com/file/t342366/test2.xyz>  which overlap. 

What other approach is there? 
Am I maybe using the one of the features wrong? 

I have attached my points below. 
Kind regards and hopefully someone can help me :)

Hi Sankhesh,

Thanks for the quick answer! Just in a nutshell, what would be needed to do programming-wise to add shading in the code?

Also I?m wondering if the situation about funding applies to bugfixes as well? I am struggling with issues related to per-volume visibility and user transforms, and I think I?ll get back to you soon with self-contained test cases once I was able to figure out which of these are on the VTK side and how to reproduce them easily.

Thanks,
csaba

Programming wise, the missing component is support for calculating
gradients across different volumes in the shader composer.

Please feel free to report bugs on VTK?s issue tracker. If it is a
relatively simple thing, we can fix it quickly.

Thanks,
Sankhesh

I'm also about to experiment with the multi-volume support. Would be
interesting to hear from you what problems you ran into wrt to
per-volume visibility / user transforms, so I know what to look out
for :) So if you file issues for those it would be great if you could
link to them here.

Cheers,
Elvis

Hi Sankhesh and Elvis,

The first issue that I was now able to confirm is that SetVisibility called on the individual vtkVolume objects within vtkMultiVolume has no effect. Not sure if this is intentional or not, but naively I'd think this is the way to show/hide a volume. I'm not fond of the idea to clear the connection in the mapper and set volume to null every time I want to hide one.
The way to reproduce this is for example adding these lines to line 118 in Rendering\Volume\Testing\Cxx\TestGPURayCastMultiVolumeOverlapping.cxx
        else if (key == "w")
        {
          this->Volume->SetVisibility(!this->Volume->GetVisibility());
        }
If you start the test interactively (-I), then nothing happens if you press w.

The other issue is that the user transform I set to the first volume seems to be ignored, while the second volume's transform is used properly. I haven't been able to reproduce it with this test yet, so I'll keep working on it until I find out what is the exact issue.

Cheers,
csaba

Subject: [vtkusers] Put a marker on a keypoint
Message-ID: <HK2PR0401MB1345FEDEA562A266C79B42B08F8F0@HK2PR0401MB1345.apcprd04.prod.outlook.com>

Hi,

I would like to label the keypoint which is closest to the 0, 0, 0 with a marker or label.

How can I SetColor to the extracted point?


Below is my code:

// Find the k closest points to (0,0,0)
unsigned int k = 1;
double testPoint[3] = { 0.0, 0.0, 0.0 };
vtkSmartPointer<vtkIdList> result =
vtkSmartPointer<vtkIdList>::New();
pointTree->FindClosestNPoints(k, testPoint, result);
for (vtkIdType i = 0; i < k; i++)
{
vtkIdType point_ind = result->GetId(i);
double p[3];
point->GetPoint(point_ind, p);
std::cout << "Closest point " << i << ": Point "
<< point_ind << ": (" << p[0] << ", " << p[1] << ", " << p[2] << ")" << std::endl;
}


Thank you so much!


Regards,

Polly

Hi,
At this point to time how can we help in proof reading and update the
observation (any repository to add the feedback?)?

For example, I found there is typo in Eq 3.7. The component t_z in the T_T
matrix is replaced by ZERO. It should be t_z. (See the screen shot below)






Thanks and regards,

If the points in the polydata comes with the normals, you can try Poisson
Surface Construction.

I have make Delaunay3D filter works for creating surfaces for points (e.g.
same for your DamBreak problem) followed by the Surface Decimation filter.

Hope that helps.

Subject: [vtkusers] vtkImplicitModeller just in "normals-field"
Message-ID: <1524650803034-0.post@n5.nabble.com>

Hello,

I'm trying to solidify my polydata, but just along the direction of its
normals.

Is there a way to kind of combine vtkImplicitModeller and vtkNormals, so
that the modeller just will create the ImageData within the "normals-field"
of the polydata?

I created a small drawing to illustrate the issue.

Subject: [vtkusers] vtkExtractSelection does not recognize GlobalIDs from
 imported vtu file
Message-ID: <1524656159204-0.post@n5.nabble.com>

I am trying to select cells from an imported vtu file by their GlobalIDs, but
vtkExtractSelection returns 0 cells.
The issue seems to be that vtkXMLUnstructuredGridReader imports the array
containing the GlobalIDs as an array of type long, but vtkExtractSelection
expects the GlobalIDs to be of type idtype.

Attached you can find a small example with a test vtu-file containing 1 cell
with a GlobalID of 333. 
The vtkExtractSelection does not recognize this cell.

Is this the expected behavior for this work flow?

Is there an option on the reader or the selection that I have to set to
handle the GlobalIDs properly?

This was tested with VTK build from git master on 25 Apr 2018.

Lukas

Subject: [vtkusers] QVTKOpenGLWidget with vtkBalloonWidget bug?
Message-ID: <CAHSJ-cgE3ZN0U9pVc52KeBrFZGrGea6=NA7Gbr4ZQruvG2hHaQ@mail.gmail.com>

Moving from the old QVTKWidget to the new QVTKOpenGLWidget, I noticed the
bug, when a vtkBalloonWidget was added to the QVTKInteractor. When
QVTKOpenGLWidget
object lose the focus, then it becomes black (when you move mouse over it,
then all is OK again).
Video is here:
https://youtu.be/aRlfiZpFFqE

The code to reproduce the bug:

#include <QApplication>

#include <QSurfaceFormat>


#include <QVTKOpenGLWidget.h>

#include <vtkRenderer.h>

#include <vtkGenericOpenGLRenderWindow.h>

#include <vtkBalloonWidget.h>

#include <vtkSphereSource.h>

#include <vtkPolyDataMapper.h>


#include <vtkAutoInit.h>

VTK_MODULE_INIT(vtkInteractionStyle)

VTK_MODULE_INIT(vtkRenderingOpenGL2)



int main(int argc, char *argv[])

{

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


    QApplication a(argc, argv);


    vtkNew<vtkRenderer> mRenderer;

    mRenderer->SetBackground(.3, .6, .3);


    vtkNew<vtkGenericOpenGLRenderWindow> mRenderWindow;

    mRenderWindow->AddRenderer(mRenderer.Get());


    vtkNew<QVTKInteractor> mRenderWindowInteractor;

    mRenderWindowInteractor->SetRenderWindow(mRenderWindow.Get());


    vtkNew<vtkBalloonWidget> mBalloonWidget;

    mBalloonWidget->SetInteractor(mRenderWindowInteractor.Get());

    mBalloonWidget->EnabledOn(); // remove this line to fix the bug
(but we need it for balloons)


    // Add a sphere for beauty (but we can get the bug without any actor too)

    vtkNew<vtkSphereSource> sphere;

    sphere->SetCenter(0.0, 0.0, 0.0);

    sphere->SetRadius(5.0);

    vtkNew<vtkPolyDataMapper> mapper;

    mapper->SetInputConnection(sphere->GetOutputPort());

    vtkNew<vtkActor> actor;

    actor->SetMapper(mapper);

    mRenderer->AddActor(actor);


    QVTKOpenGLWidget vtkOpenGlWidget;

    vtkOpenGlWidget.SetRenderWindow(mRenderWindow.Get());


    vtkOpenGlWidget.show();

    mRenderWindow->Render();


    return a.exec();

}



Without this line:

mBalloonWidget->EnabledOn();

all works good.

And there are no problems with old QVTKWidget, but there is this bug with
new QVTKOpenGLWidget and balloons enabled.

Compiler is MSVC 2017 32 bit, VTK 8.1.0, Qt 5.10.1

The question is:
Is this a VTK bug or some my mistake?

Thanks Sankhesh.
What would be an efficient approach to assign HSV color for each of the
points, given that 1) there are a lot of points ~50k, and 2) each point has
it own specific color.

Thanks,

I am new to VTK.js and working on some examples. I am facing issues to check what not there in VTK.js which is available in VTK library. I was finding description about VTKStripper and after searching VTK where it is available in VTK under 'Filters\Core'.

However, when i take same into VTK.js, i found its not available.

Could you please let me know if its really not available in current VTK.js or am i missing something here?

Shrikant,

You are not wrong. Just a handful of VTK filter equivalents are presently
available in vtk.js.

Thank you very much for your answer. 

I will try the delaunay, followed by the surface decimation filter. 
I normally have the problem with the breaking wave at the end of the
dambreak. 
How do you work with those chaotic structures?

I have a further problem related to surface extraction, 

when I use the vtkextractsurface algorithm it places large half spheres
where a couple of
particles are clustered together. 

See picture. 

How do I reduce the size of those spheres? ->SetRadius is related to the
seen/unseen voxels

kind regards

Subject: [vtkusers] Is there possible to use and manage many vtkLineWidgets
 in a scene?
Message-ID: <1524731206340-0.post@n5.nabble.com>

First, I render a 3D model. When an user clicks on the model's surface, I
generate and draw a sphere. For the first 2 clicked points, I generate a
line. But from the 3rd clicked point,  I use a previous point and the
current point to make a line. 

Is there possible to use a vtkLineWidget for each generated line? If it is
possible, how to implement it?

Yes, the easiest way is to install it with 'pip', using python:
https://pypi.org/project/vtk/
pip install vtk

 Aron, thanks for that.? Which version of python works here?
I'm impressed by the VTK literature.? So I want to test out the VTK 8.1.0 libraries with GNU C++ and Matlab via MEX files.? I have example programs already, but I just cannot get the VTK libraries installed on Windows 10.? I'm surprised the ready-to-run binaries are not on the VTK website.??
If I install with 'pip" using python, will VTK only work with python or will I be able to link it with GNU C++ programs like I want?
Thank you.

Python 2.7 or 3.5+ should work.
I believe the binaries installed by pip are build with Visual Studio, so I
doubt you would be able to link to them with GNU C++.
But, I don't have experience with what you are trying to do, so I will have
to defer to the list...

There are MinGW-W64 packages available from msys2:

https://www.msys2.org/
https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-vtk

I doubt you would be able to link to them with GNU C++.

That is correct.

Hi Sankesh,

Can you please reply to my question about SetVisibility? See below.

Thanks,
csaba

Hi Sankhesh and Elvis,

The first issue that I was now able to confirm is that SetVisibility called on the individual vtkVolume objects within vtkMultiVolume has no effect. Not sure if this is intentional or not, but naively I'd think this is the way to show/hide a volume. I'm not fond of the idea to clear the connection in the mapper and set volume to null every time I want to hide one.
The way to reproduce this is for example adding these lines to line 118 in Rendering\Volume\Testing\Cxx\TestGPURayCastMultiVolumeOverlapping.cxx
        else if (key == "w")
        {
          this->Volume->SetVisibility(!this->Volume->GetVisibility());
        }
If you start the test interactively (-I), then nothing happens if you press w.

The other issue is that the user transform I set to the first volume seems to be ignored, while the second volume's transform is used properly. I haven't been able to reproduce it with this test yet, so I'll keep working on it until I find out what is the exact issue.

Cheers,
csaba

I'm also about to experiment with the multi-volume support. Would be interesting to hear from you what problems you ran into wrt to per-volume visibility / user transforms, so I know what to look out for :) So if you file issues for those it would be great if you could link to them here.

Cheers,
Elvis

Thanks for reporting the issue Csaba. This might be an unintended
side-effect of vtkMultiVolume in the GPU mapper.

I've created an issue here: https://gitlab.kitware.com/vtk/vtk/issues/17302
to keep track of it.

Thanks,
Sankhesh

Thank you Sankhesh!

It?s good to know that this is indeed a bug. Thanks a lot for creating the issue and for looking into it!

Best,
csaba

Thanks for reporting the issue Csaba. This might be an unintended side-effect of vtkMultiVolume in the GPU mapper.

I've created an issue here: https://gitlab.kitware.com/vtk/vtk/issues/17302<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.kitware.com%2Fvtk%2Fvtk%2Fissues%2F17302&data=02%7C01%7Ccsaba.pinter%40queensu.ca%7C58f618cc13fa44e47a6408d5abb89b4f%7Cd61ecb3b38b142d582c4efb2838b925c%7C1%7C1%7C636603731736610629&sdata=dVaGE7Gcde%2Bdkx8u74taI6VdQNU%2FLTkOeHyFooppcZ8%3D&reserved=0>
to keep track of it.

Thanks,

Hi Sankhesh and Elvis,

The first issue that I was now able to confirm is that SetVisibility called on the individual vtkVolume objects within vtkMultiVolume has no effect. Not sure if this is intentional or not, but naively I'd think this is the way to show/hide a volume. I'm not fond of the idea to clear the connection in the mapper and set volume to null every time I want to hide one.
The way to reproduce this is for example adding these lines to line 118 in Rendering\Volume\Testing\Cxx\TestGPURayCastMultiVolumeOverlapping.cxx
        else if (key == "w")
        {
          this->Volume->SetVisibility(!this->Volume->GetVisibility());
        }
If you start the test interactively (-I), then nothing happens if you press w.

The other issue is that the user transform I set to the first volume seems to be ignored, while the second volume's transform is used properly. I haven't been able to reproduce it with this test yet, so I'll keep working on it until I find out what is the exact issue.

Cheers,
csaba

I'm also about to experiment with the multi-volume support. Would be interesting to hear from you what problems you ran into wrt to per-volume visibility / user transforms, so I know what to look out for :) So if you file issues for those it would be great if you could link to them here.

How different is what you need from writing the rendered output directly 
to a file using one of the vtk*Writer classes?

Correct me if I'm missing something.

Hi, Paul
The difference is to get to the point where there is something rendered, without having to open a window on the terminal. 
In the case where I already know (or can calculate from the image data) the colour function and the transparency function, I know what camera angle I want and so on, I just want to run a background job on a remote workstation/cluster node to render that same view for a number of similar images (of the same object in different time steps) Instead of sitting on my computer watching it. 

But, the problem is that with the way I know how to do it, the creation of the render window trys to get a GL context, but it can't do that . 

If I try in python on a X-window connection even, I get the following 
ERROR: In /home/ilan/minonda/conda-bld/work/VTK-6.3.0/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 394
vtkXOpenGLRenderWindow (0x7f47c0fda000): Could not find a decent visual


But maye the capability isn't compiled into the python package  from Anaconda?? 
Is there a python package  I can grab that has software rendering? 




I tried to buld the c++ from source of 7.1.1. But not successfully. ..

./CylinderRenderingProperties 
ERROR: In /dls/science/users/kny48981/sources/vtk/VTK-7.1.1/Rendering/OpenGL2/vtkXOpenGLRenderWindow.cxx, line 320
vtkXOpenGLRenderWindow (0xfc18a0): Could not find a decent config

Due to the lack of document, I did not know that vtk has a widget named
vtkPolyLineWidget. To solve this problem,  I use a list of clicked points to
make a vtkPolyLineRepresentation and then use this representation as an
input to a vtkPolyLineWidget.

2-> You can use a modern version of X that supports running a dummy framebuffer. This can be installed in user mode so you don't even need to have root on the system.
Xdummy standlone
You can start a new display using the dummy driver without needing any special privileges (no root, no suid), you should specify your own log and config files:
Xorg -noreset +extension GLX +extension RANDR +extension RENDER -logfile ./10.log -config ./xorg.conf :10




However, the link within the link that this link refers to does not say anything about how o install it in user mode. Do you know anyting about that ?
The nodes do not have Xorg installed.
A workstation already has Xorg running so I don?t understand  If I run as specified in the link, it either doesn?t work *cannot specify ?logfile with elevated priviliges*  or else if I skip the logfile, it opens a *real* display on top of my display.
I don?t understand which part of the command is supposed to access the dummy driver.



com09-10 ~]$ Xorg
-bash: Xorg: command not found

If it's not in the python , what needs to be done, at the time of prior questions it seemed to be a compile-time option of the VTK library, is that still the case, Any exaples on line that are for the current release ?

Thanks Max, that seems to install if I use a conda enviromnet to avoid messing up other users ?


conda create --prefix /path/to/my/local/env
source activate /path/to/my/local/env
conda config --add channels conda-forge
conda install mesalib vtk


It?s still installing ? but it looks like then I have to update to Python 3 and vtk 8 ????

What is the change in vtk8 that means the composite function doesn?t exist ? what do I use instead?

Thanks

Hey folks,

We are going to put out an 8.1.1 release in the next couple of weeks.

If you have substantial bugs/fixes that you really want to see in it,
please tag them with the 8.1.1 milestone in the issue tracker.

This will be a patch release so we are only looking for bug fixes not new
features over 8.1.0.

Hello VTK-Users,

any Code after "renderWindowInteractor->Start();" won't be executed until I
close the RenderWindow. I want it to stay open and translate and rotate one
actor with respect to another one by clicking buttons or entering values via
console. Is there a good way to do this? I read about Timers.. but I want to
change the position and orientation time-independent and in an arbitrary
sequence of x,y,z,a,b,c.

Hi Ashef,
VTK and ITK do not provide any prescribed way to do a GUI - there are
hundreds of choices you could use, and they would all work. For instance,
ParaView is built on VTK, and uses QT for it's GUI. You could also build a
gui in Python, perhaps using wxWidgets python bindings.
Since you are working with DICOM, instead you may want to look at 3D Slicer
(https://www.slicer.org/) which is an open-source medical visualization app
that uses VTK and ITK. You may be able to write a plugin for it which does
what you want, and take advantage of all it's other features.

The best choice may be something that you are familiar with, or something
that you can get help with!
Good luck,
Aron

In addition to what Aron said, there are some nice examples using Qt
available on the VTK Examples GitHub:

Subject: [vtkusers] How to elevate a vtkImageData into a vtkAlgorithm object?
Message-ID: <1525108081562-0.post@n5.nabble.com>

For some type-juggling, I would like to transform an  object into a  object,
very much like the  for  objects.I found the  ImageAlgorithmFilter example
<https://www.vtk.org/Wiki/VTK/Examples/Cxx/Developers/ImageAlgorithmFilter>  
that shows that something like this has existed. However, it seems not to be
available in vtk 8.1.0.Does anyone know more about this?Many thanks for your
help!

The vtkImageChangeInformation filter is probably the best choice, since
it's a passthrough filter (it doesn't make a copy of its input).

You can also try vtkTrivialProducer, it's a special vtkAlgorithm that does
nothing.

Just create a vtkTrivialProducer and then call SetOutput() to set what its
output should be.
