[SciPy-User] Triangulate point cloud

[gary ruben]

Hi Vasco,

Another possible option is vtk's Delaunay3D method. I used this a long time
ago when it was one of the only options I could find that could reliably
triangulate points on the surface of a sphere. It has a couple of
parameters you can fiddle with to affect its behaviour:
