I am (still) new to CGAL and would like to know the
a) Given a Polyhedron_3 mesh, how to make an even coarser mesh
out of it? That’s about losing details intentionally, as opposed to the
subdiv method introduced in the tutorial.
b) Given a Polyhedron_3 mesh (made by polygon facets), is
there a way to convert it to a Triangulation_3 using tetrahedrons?
Any hints are extremely welcome.
