WebDec 7, 2009 · 3. For the convex case (no dents in the surface which cause surfaces to cover each other) and a triangle mesh, the simple solution is to calculate the center of the polyhedron and then connect the three corners of every face with the new center. If you don't have a triangle mesh, then you must triangulate, first. Delaunay triangulation might help.
