[vtkusers] [Java] VTK volume rendering

[Aashish Chaudhary]

vtkProjectedTetrahedraMapper is the class that meant for UnstructedGrid.
Are you using OpenGL2 backend or OpenGL1? Also, any information on your
system (os, graphics card), data type and size would be nice to know. The
other thing you can do is sample your grid into vtkImageData and then you
can use GPU Mapper.

Thanks,
