[vtkusers] vtkVolumeTextureMapper3D in VTK 7.1?

[Alvaro Sanchez]

Hi Shark,

unfortunately there is no current plan of porting vtkVolumeTextureMapper3D
to OpenGL2
, as far as I know.  We will soon however support image down sampling in X
and Y which
should serve as additional knobs to tweak the performance of
 GPURayCastMapper in
OpenGL2 (only sample distance can be currently adjusted).

Could you provide more detail on the size of the dataset you are rendering
and your GPU
specs?

Thanks,
Álvaro
