If you’re trying to wrap points not solids I’d suggest looking at alpha shapes.

I remember Laurent posted some 3d implementation:

Alpha Shape 3D

Here is an implementation of 3D alpha shape, it is using 3D DelaunayCell (standard GH component ??). https://doc.cgal.org/latest/Alpha_shapes_3/index.html https://doc.cgal.org/latest/Alpha_shapes_2/index.html I liked a lot the explanation of Alpha Shape of CGAL site “Imagine a huge mass of ice-cream making up the space R3R3 and containing the points as “hard” chocolate pieces. Using one of these sphere-formed ice-cream spoons, we carve out all parts of the ice-cream block we can reach withou…
