CGAL users discussion list

Hi Wesley,

This is not an answer to your question, but a related remark.
We are working on extensions of 3D triangulations to the torus (periodic 
space in the 3 dimensions) as well as other spaces.
This should be integrated in future CGAL releases.

In fact we reuse the same CGAL kernel, but we modify the design of the 
3D triangulation package. A first research report explaining the main 
ideas of this new design is available from there:

Best,
        Monique Teillaud
