Hello,

I have an AABB tree storing triangular faces coming from different surface mesh instances. I'm using that data structure to compute intersections with rays, but currently the primitive ID that I obtain for each intersection query is just a face index (i.e., an instance of CGAL::Surface_mesh<Point_3>::Face_index). I would like to know which surface mesh this face belongs to. Is there a clean way to do this? I was thinking of providing my own AABB primitive somehow, but I'm not sure if this is the proper way to do it (and in fact I'm not even sure how this can be done).

Thanks in advance for your help,

Lucio
