Great progress, Monique!
Eventually, my implementation doesn't use triangulation on a sphere. But this topic is still interesting for me.

Alessandro, the implementation of triangulation on a sphere using convex hull of polyhedron works quite fast, but you will probably lose your information in vertices of triangulation, if you store any such info, because when you get convex hull CGAL converts vertices in another structures. This is the problem I faced, but I have found a solution (with help of this forum). If you are interested in my approach, I can tell you it with more details.

Hi,

unfortunately, not yet. The code is working, it is very fast, but there
are a few minor details to tune, and most of all it is not yet
documented...

Best,
