[vtkusers] vtkVolumeTextureMapper3D in VTK 7.1?

[Sankhesh Jhaveri]

Hello Shark,

As of now, there are no plans of supporting the vtkVolumeTextureMapper3D with
the OpenGL2 backend. Based on my understanding, the performance of 3D
texture mapping (accumulating samples one texture slice at a time) vs ray
casting (accumulating samples one ray at a time) would be similar when
using hardware acceleration.

For software rendering, you should try the vtkFixedPointVolumeRayCastMapper.
It has been improved and optimized over the recent past. Another promising
approach is using the OSPRay
<https://blog.kitware.com/vtk-and-paraview-now-with-ray-traced-rendering/>
backend
which leverages Intel’s OSPRay <http://www.ospray.org/> ray tracing engine.

Hope that helps.
Sankhesh
