[vtkusers] nightly build (8.1.0?) where did vtkVolumeTextureMapper3D go

[Andras Lasso]

If there are errors in the current GPU volume mapper then they certainly have to be fixed, but I would rather have only one GPU volume mapper in VTK, which works well. If there were different variants then developers attention might be divided between them and developers may be distracted by users asking help for unsupported classes.

Until error in the current GPU volume mapper is fixed, you can build the old mapper as part of your application or keep using an earlier VTK version.

Hi Aashish,

I'm not sure what specific reason(s) that Brian Davis would want the vtkVolumeTextureMapper3D back; we want it back too.

For our case, it is because the new CPU/GPU ray cast volume mapper is not working correctly when depth peeling is enabled (for multiple volumes) and also when rendering the scene in stereo (left and right images are the same). I think it is good to have a backup when the only volume mapper doesn't work.
