demo/AABB_tree

Yes that's exactly what I am looking for!  CGAL is amazing.  It appears that there is a built in render function for openGL and polyhedrons.  May I suggest that someone updates the QT documentation page for CGAL with a note that AABB_tree is relevant ?  It may reduce the number of silly questions in the future :)

Merci pour votre temps et consideration.
