[vtk-developers] Supported texture size in vtkOpenGLVolumeTextureMapper3D

Hello,

The function vtkOpenGLVolumeTextureMapper3D::IsTextureSizeSupported
appears to restrict texture size to a maximum of 128*128*128 and
128*256*256, for 4 component and less than 4 component volumes
respectively.

Removing the restriction appears to work fine with an NVIDIA 7600, and
allows higher quality textures to be used.

Is anyone aware of why this restriction is in place?


Regards,


John.
