Hello,

I am trying to construct triangulation for a large set of data that represents the contour of a heart. The data is in (x,y,z) and has various spacing. I have attempted a delauney triangulation and using a convex hull however the shape is both convex and concave so with convex hull I loose much of the detail. Are there any functions or ways to make triangles only along the surface or to specify that if a triangle is above a given size to ignore it. In essence I'm looking to render this complex surface.

Thank you.

Have you tried an ISOSURFACE with a PATCH object?
