[vtkusers] volume texture mapping based on GeForce3 graphics card

[Jianlong Zhou]

Hi, vtk users,

I want to render volume with texture mapping based on GeForce3 Graphics card in VTK. 
To realize this function, I think I should derive some vtk classes (e.g. 
vtkVolumeTextureMapper2D, etc.) and add GeForce3 functions (e.g. register combiners, 
etc.) into the derived classes. Does anyone have the experience to program combining 
VTK and GeForce3 graphics card to do volume rendering? Would anyone give me any 
ideas about combining VTK and GeForce card to do volume rendering?

Thank you in advance.

Best regards,

Jianlong
