dear Jens,
the AABB tree component from the 3.5 beta may answer your question:
http://www.cgal.org/Manual/beta/doc_html/cgal_manual/AABB_tree/Chapter_main.html
I let you see the demo which allows generating N random points inside a polyhedron.

Hi all,
I frequently need to orient the vertices of triangles (ccw or cw). Is
there a simple way to do this? The reference point would be the inside
of a polyhedron but I can immediately think of a lot of exceptions (e.g.
concave polyhedra). Could I use an infinite point as a reference? Not
exactly sure how infinite points are defined...
Or does anybody know a good solution? Thanks for your help,
Jens
