Hi there, thanks for sharing your code! I am trying to compile it using cmake in the git directory, but facing a problem not finding:

include "vtkVolumeRenderingFactory.h"

and also.

include <vtkstd/string>

A few lines explaining the compiling process you are using would be awesome. I haven't find vtkVolumeRenderingFactory.h in my VTK 6.2 folder.

Thanks! Pablo

Dear Pablo,

You are right I must add more document about the installation and compiling but I was quite busy during last weeks... The code has been tested and compiled by VTK 5.8 I havent try it by 6.2 so it might be that...

Regards, Mehdi

Dear Mehdi,

Indeed very nice code and I'd like to use. I have tried to compile (after cmake) and I got immediately this error:

[ 7%] Generating vtkGPUMultiVolumeRayCastMapper_ShadeFS.cxx, vtkGPUMultiVolumeRayCastMapper_ShadeFS.h make[2]: ./vtkGPUMultiVolumeRayCastMapper_ShadeFS.cxx: Command not found make[2]: * [vtkGPUMultiVolumeRayCastMapper_ShadeFS.cxx] Error 127 make[1]: * [CMakeFiles/vtkGPUMultiVolumeRender.dir/all] Error 2 make: *\ [all] Error 2

I am not a VTK expert, let me know if I am doing something wrong.

I agree that few lines explaining the compiling process will be very nice.

Davide.

P.S. I am using VTK6.0.0 (which works when I compile the examples).

Punzo commented 10 years ago

The problem can be that I didn't compile something needed from your code?
Follow the the value of the variables that I used to compile the VTK:

BUILD_DOCUMENTATION ON BUILD_EXAMPLES ON BUILD_SHARED_LIBS ON BUILD_TESTING ON CMAKE_BUILD_TYPE Debug CMAKE_INSTALL_PREFIX /usr/local VTK_EXTRA_COMPILER_WARNINGS OFF VTK_Group_Imaging ON VTK_Group_MPI OFF VTK_Group_Qt ON VTK_Group_Rendering ON VTK_Group_StandAlone ON VTK_Group_Tk ON VTK_Group_Views ON VTK_WRAP_JAVA OFF VTK_WRAP_PYTHON OFF VTK_WRAP_TCL OFF

I look forward to hear from you. Thanks.

bozorgi commented 10 years ago

Dear Davide,

You are right I must write some more documantation about how to install the code...

This might be related to the VTK version that you use (I have test the cose only with VTK 5.8) or the installation of VTK is not correctly done... Could you please tell me the version of Cmake and your operationg system also...

Best regards, Mehdi

Hi Mehdi,

I read your paper and I think you did a very good job. I read another paper of two years ago and the vtk multivolume rendering had a lot of limitation.

Do your code allow also different spacing (and size of the volume itself) for the different volume without artifacts?

So going back to my issue: I am running on ubuntu 14.04 64 bit. CMake is 2.8.11.2. ( Latest nvidia driver.) I think however that the problem can be related how I compiled VTK6.0. So as I have already reported the "main" vtk cmake variable:

BUILD_DOCUMENTATION ON BUILD_EXAMPLES ON BUILD_SHARED_LIBS ON BUILD_TESTING ON CMAKE_BUILD_TYPE Debug CMAKE_INSTALL_PREFIX /usr/local VTK_EXTRA_COMPILER_WARNINGS OFF VTK_Group_Imaging ON VTK_Group_MPI OFF VTK_Group_Qt ON VTK_Group_Rendering ON VTK_Group_StandAlone ON VTK_Group_Tk ON VTK_Group_Views ON VTK_WRAP_JAVA OFF VTK_WRAP_PYTHON OFF VTK_WRAP_TCL OFF

and with this settings I didn't have issues during the compilation of the VTK examples or small code of mine. If you can send me the list of variables that you used in the compilation of vtk5.8 I can try using the same setting of yours. I mean that I'd like to know if I need for example the wrapper. If you think can be useful I can send you the list of all the variable (the advanced mode).

Thank very much for your support.

Cheers,

Davide.

Dear Davide,

Thanks, infact the sceleton of the code is same as the previous paper but solving some of the issues...

Yes it does support; you can have both different size of volume and/or different spacing.

I dont see anything wrong in the compiling parameter but I cannt double check it with the actual parameter which I used since I am in Japan to attend a conference... What I can tell is that I did not changed any default parameter. I guess your cmake can not found the VTK build files somehow...

phcerdan commented 10 years ago

@Punzo I think the code is not compatible with VTK 6. VTK developers reformat files and are not really worried about backwards compatibility. I had the same error than you the first time I tried to compile it. That error trying to execute a cxx file is because cmake have not found vtkEncodeString. You should go to the CMakeLists and modify the lines: (-) COMMAND ${VTK_ENCODESTRING_EXE} (+) COMMAND /your/path/to/VTK/bin/vtkEncodeString-6.2

I have also added to CMake: include_directories(${PROJECT_SOURCE_DIR})

The error I have now is that it cannot find: #include "vtkVolumeRenderingFactory.h" I have checked in VTK git repo and they don't have it, so it must be a re-factored file. It should be easy to solve by @mohammeb, with a bit of playing in VTK 6! I am not going to use this software in the short term, so sorry to not provide any extra help.

Good luck!

Punzo commented 10 years ago

Hi Pablo,

thanks you very much for the information, it was very helpful. Indeed I have also got your same issue about the "vtkVolumeRenderingFactory.h".

Cheers,

Davide.

Hi All,

I am actually planning on porting your code to VTK6 in the near future, would be happy to contribute it back if you are interested.

Best,

LalaChen commented 9 years ago

Hi, I try to import this project to VTK6.3. I succee import into VTK Library (VTKRenderVolumeOpenGL and VTKRenderVolume) but with wrong result. I can't see the second volume.

I'm sure the transfer function is containing some values in my data. But I just can't see it.

P.S. I got some wrong information.

Warning: In D:\SVNData\BCBTI\Lib\VTKx64\Common\Transforms\vtkTransform.cxx, line 194 vtkTransform (0000000005DFDDE0): InternalUpdate: doing hack to support legacy code. This is deprecated in VTK 4.2. May be removed in a future version.

Thanks.

LalaChen commented 9 years ago

Hello, I think it's my fault. When I adjust my transfer function of secondary volume, it's display on screen. But I have another problem. If I need to improve its performance, what should I do? By the way, my data is 512_512_400. the secondary data is 256 cube.

bozorgi commented 9 years ago

Hei, What is the fps now? Which machine are you using?

Hi, the fps is 1.26 run two volumes with 512 x 512 x 400 and 256^3 .

And my machine is as follow : CPU : Xeon E1231-v3 3.40GHz VGA : Nvidia 960GTX 2GB ram.

I will try to build on x64-release. If I have any result, I will tell you.

By the way, I build this with x64-debug on visual studio 2013.

Thanks.

LalaChen commented 9 years ago

I find the reason of my problem.

  void vtkKWScalarField::Update()
      GLint width;
      glGetIntegerv(vtkgl::MAX_3D_TEXTURE_SIZE,&width);
      this->Loaded=textureSize[0]<=width && textureSize[1]<=width && textureSize[2]<=width;//There is the point cause we needs to loading each frame.

Can you tell me some information about this ?

Thanks,

bozorgi commented 9 years ago

I think your GPU is not capable of loading big 3d textures in its memory... What kind and model of GPU are you using?

LalaChen commented 9 years ago

I'm survey my problem. And I find a clue.

In function RenderSubVolume int loaded = texture!=0 && texture->IsLoaded() && this->GetTransformedInput()->GetMTime()<=texture->GetBuildTime() && (this->GetMaskInput() ? this->GetMaskInput()->GetMTime() <= texture->GetBuildTime() : true) && texture->GetLoadedCellFlag()==this->CellFlag;

In vtkOpenGLGPURenderMapper, Load is false only in first frame. But is vtkMultiOpenGLRenderMapper. Load is always false.

I can see the result and the result seems right.

But I don't know why I get fail resulf of loaded(loaded == false).

Can you run your code and test this line is always false each frame?

After test, I find I get loaded failure of this line. (this->GetTransformedInput()->GetMTime()<=texture->GetBuildTime() ) I will survey it and tell you the result.

thanks.

LalaChen commented 9 years ago

Sorry. I think I find the result.

I modify several lines for build success. But I misunderstand you means.

In version VTK6.3, Update function is removed. I modify the line [this->TransformedInput->Update();] to [this->TransformedInput->Modified();] when mapper is checking invalid rendering.

I'm sorry about this.

Hi, Thanks for sharing the code. I am completely new to VTK and of course multi-volume ray casting. Until now, I have installed VTK. I tried to compile the code thus provided using cmake. A solution file for the multivolume demo was created. I built it and nothing happened. I have no idea what to do next. how to use the code u provided. Please help me out with few basic installation steps and how to use the code. I have done few examples using VTK. Anyone, please help me. I really appreciate any help.
