Hi,

ATM I am studying a certain kind of finite element methods with overlapping 
meshes. Therefore I am adding some intersection functionality to our mesh 
classes (belonging to the problem solving environment 
http://www.fenics.org/wiki/DOLFIN). These corresponds to the functionality 
provided by CGAL: A boolean function "do_intersect" and  an "intersection" 
function, which computes the actual intersection in terms of Nef Polygons.
Depending on the dimension a mesh is purely build up by segments, triangles 
or 
tetrahedrons. 
Everything is fine except that I am sticking with 3d case. So is there an 
easy 
(and fast?) work around for the missing do_intersect function, which takes 
two 
tetrahedrons (or even 2 Nef_3 polyhedrons)? Any hints or pointers are very 
much appreciated!

Kind regards,
Andre
