[vtkusers] Linux + VolumeTextureMapping3D

[Patrick D. Emond]

Hello,

When attempting to use vtkVolumeTextureMapper3D to render a scene I'm 
getting the following error:

ERROR: In 
/usr/local/src/VTK-5.0.2/VolumeRendering/vtkOpenGLVolumeTextureMapper3D.cxx, 
line 125
vtkOpenGLVolumeTextureMapper3D (0xb33c4008): required extensions not 
supported

The code in question has been compiled and ran on a Windows machine 
without any problems, and though it compiled fine on Linux (thank you 
CMake) I get this error.  Is there a development package of some kind 
that I should install?  Has anyone else had problems getting 3D texture 
mapping working under linux?

I'm running:
Ubunto Linux 6.10 (Edgy Eft)
ATI Radeon x700 Mobile
fglrx binary drivers

Thanks for any help people can offer,
Patrick
