[vtkusers] GPU for computation

Hi Sunil,

Concerning the vtkDelaunay3D algorithm, it is not implemented on GPUs 
and I don't believe there is currently an option for that (in VTK and 
generally in the public domain).

While the vtkDelaunay3D is convenient as directly available in VTK and 
with VTK licensing terms, I have experienced significant speed gains 
using TetGen (http://wias-berlin.de/software/tetgen/) - this on meshes 
with 0.5 to 2 million tetrahedral elements. The only drawback is that 
one has to develop his/her own methods calling TetGen from VTK, and 
abide to the specific licensing conditions.

Please note also that a number of alternatives exist: 

Best Regards,
