Hi all,

If I have a polyhedron, each vertex knows a halfedge pointing to it and
each halfedge knows a facet it is part of. I need to know to which
polyhedron a vertex, halfedge or facet belongs to ( I was thinking about
facets having a pointer to the polyhedron, that would be enough since I
could "ascend" from vertex to facet if I need to know to which
polyhedron a vertex belongs). Is it possible to include that (or does
that already exist and I have just missed it)? I could just add a
pointer to a facet and use it after creation of the polyhedron, but I am
not sure what happens to all during e.g. erase_center_vertex and so on,
would I need to update the pointers?

Thanks for your help,

Jens
