[vtkusers] GPU volume rendering

Fri Apr 17 08:08:16 EDT 2009

Hi Karthik,
sorry to bother you...I'm trying to run GPURenderDemo passing -DICOM <directory>
the directory with my .dcm images which are dicom images....now, does it take in input a multiSlice->single file volume or a sequence of files?

Kind Regards.
Giancarlo

try 

  c:\Program Files\.....\ctest.exe -D Experimental -C Debug

I think you've built your project for the "Debug" configuration right ?

By default, for multiconfiguration generators such as visual studio, it assumes that you have built your project for the Release configuration. The "-C Debug" explicitly asks it to test your Debug tree...

Also, if I understand correctly, you were looking for GPU accelerated volume rendering. This is not CUDA based and hence of little concern if your card does not support CUDA. 

Its uses GLSL fragment shader programs and should work fine with your card.

Your GPU should do just fine.. I believe it supports all the required extensions.

If you run into issues, you can run the tests as :
  cd VTKEdge\binaryDirectory
  c:\Program Files\......\ctest.exe -D Experimental 

and see your results on the dashboard :

Hi Karthik,

I'm trying to run all the tests executable for the volume rendering based on GPU, and I wonder what kind of GPU is required if there is one required...I have an NVIDIA 7900 GS which I believe it has a GPU.

Kind Regards.

Giancarlo:

As I mentioned earlier, please post your CMakeCache.txt file, NOT CMakeLists.txt .

The CMakeCache.txt file should be found at the top level of your binary directory.

Thanks

In attachment the CMAKELIST.txt file which comes with the distribution...I've never edited that.

There is no relation dependency of CUDA related sources and KWWidgets in VTKEdge. Please post your configuration errors to the list and also post your CMakeCache.txt (You should find this file in your binary directory)

I dunno why as I have CUDA installed, as I turn on the _use_CUDA option with CMAKE it requires something related to KWidget....

No VTKEdge itself does not require KWWidgets.  

You need them only if you'd like to build the GUI based paintbrush tool demos. You don't seem to need any of those

does it require any widgets? like Kwidget?

Giancarlo:

VTKEdge does build with VTK CVS and if I am not mistaken also builds fine with VTK-5-4.

Could you please post the errors you are getting to the list.

Here is a link to last night's dashboard :

Hello everybody,

does anybody know about a library for GPU accelerated volume rendering compatible with VTK?

I'm struggling in finding something nice....and I'm trying to compile VTKedge but...with no success with VTK 5.4

Kind Regards.
