I would like to pick up on an older thread regarding VTK and CUDA, or more<br>
specifically the vtkGPUVolumeRayCastMapper and CUDA. I'm very much a<br>
beginner when it comes to GPU programming, but from having a look at the<br>
implementation of that class it looks like the vtkGPUVolumeRayCastMapper is<br>
based on fragment shaders.</blockquote><div><br>That's right. No CUDA here.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> To what extent does a CUDA enabled graphics board<br>
actually help there, and is anybody aware of any initiatives to provide an<br>
actually CUDA-based implementation for VTK volume ray casting?<br></blockquote><div><br>Benjamin Grauer added that a CUDA volume renderer to 3D Slicer. Its inactive at the moment and does not support certain features. You can see more on this wiki page : <a href="http://wiki.na-mic.org/Wiki/index.php/2008_Winter_Project_Week_VolumeRenderingUsingCuda" target="_blank">http://wiki.na-mic.org/Wiki/index.php/2008_Winter_Project_Week_VolumeRenderingUsingCuda</a>.<br>

Btw, I found the information about the memory properties very helpful.<br>
<br>
Thanks,<br>
