<p>Hi Sunil,</p>
<p>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).</p>
<p>While the vtkDelaunay3D is convenient as directly available in
VTK and with VTK licensing terms, I have experienced significant
speed gains using TetGen (<a href="http://wias-berlin.de/software/tetgen/" target="_blank">http://wias-berlin.de/softwar<wbr>e/tetgen/</a>)
- 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.</p>
<p>Please note also that a number of alternatives exist:
