Hi all,
As far as my understanding goes about Nef Polyhedra, it is a kind of cellular model by which we can represent and operate upon the non-manifold geometries (please correct me if wrong).
Most of the CGAL examples that I have seen so far usually convert a simple Polyhedron into a Nef Polyhedron, which means that we always load manifold geometric data into a Nef Polyhedra.

If I need to operate upon a nonmanifold geometry like a sphere enclosed in a box, I am not sure how to load such data into Nef Polyhedra.

Is there a way to populate the Nef Polyhedron directly, using some kind of facet data? Can someone please point me to example code to do that?

thanks and regards,
