[vtkusers] volume rendering using CPU instead of GPU

[Mark Roden]

To follow up on my own question, I've found
vtkOpenGLGPUVolumeRayCastMapper

However!  I'm getting the following error log:

ERROR: In ..\..\vtk-5.6.1\VolumeRendering\vtkOpenGLGPUVolumeRayCastMapper.cxx,
line 4173
vtkOpenGLGPUVolumeRayCastMapper (00000000085BEF20): Rendering failed
because the following OpenGL extensions are required but not
supported:

Since no particular extension is reported, I'm unsure of how to
proceed.  The same error happens if I use vtkGPUVolumeRayCastMapper as
well, suggesting that vtkGPUVolumeRayCastMapper just thunks down to
vtkOpenGLGPUVolumeRayCastMapper (at least in this instance).

I've updated my graphics drivers to be the latest greatest from
ATI/AMD, for the 57xx series of cards.

The result is an empty volume.

Any thoughts on how to fix?

Thanks,
Mark
