[vtkusers] Triangulate surface points?

[Cory Quammen]

Philip,

Please take a look at

http://www.vtk.org/doc/nightly/html/classvtkSurfaceReconstructionFilter.html

and

http://www.vtkjournal.org/browse/publication/718

I don't have direct experience with these classes, but they may have what
you need.

HTH,
Cory
