CGAL users discussion list

Dear Daniel,

I waited until April the 2nd before answering...
As mentioned on the CGAL 'work in progress' web page, we are actually 
working on a 3D periodic triangulation package for CGAL. I hope it will 
appear in the next public release, though there is still some work left.

I am interested in learning more about the way the problems arise in 
applications. What do you mean by "kernel for toroidal conditions"? Do 
you need specific functionality at the kernel level?
Our approach is instead to use the standard CGAL kernel without 
modification, and we handle periodicity at the triangulation level.

See 
http://www-sop.inria.fr/geometrica/team/Monique.Teillaud/other-geometries/
for current results. (The running times are better today than what was 
reported in the preliminary publications, the performance is roughly 
only 30% lower than in R^3.)

Best regards,
        Monique Teillaud

PS: congratulations to Andreas for his 1st April joke ;)
We are not expecting any Nobel price, but still, I think this package 
will have many applications.
