CGAL users discussion list

[Joachim Pouderoux <>]

Hello,

I am trying to evaluate the new CGAL feature that allows to efficiently intersect two polygonal

meshes (CGAL::Polygon_mesh_processing::corefine_and_compute_intersection).

In my context, it is important to be able to track down from which initial input mesh face

a face in the triangulated mesh output comes from. It looks like this is where the named property

called "face_patch_map" could have been useful. However, if I am correct, this feature is not

supported by the algorithm. Am I wrong?

Is there another (topological) way I could reconstruct those face ids?

Thanks for your help,

Best,

Joachim
