Hi Community,


I am using the Delaunay triangulator from OSG. For simple cases it works fine, but not enough for real world ones. Any suggestion for constrained Delaunay triangulation library?


Thanks a bunch as always!


Nick

Hi, Nick, Triangle (https://www.cs.cmu.edu/~quake/triangle.html) is the
one that usually comes to mind for that task.

Thanks Alberto. I think I come across this one too. The old libtriangle written in C? Ehm ... I would welcome more modern code - while reading libtriangle, it hurt my head how it should be used. But thanks anyway

Heh Smile I think the words for this library is "trusty" and "proven". The
main feature is its use of the "exact predicates" which can overcome
all the inconsistencies due to numerical errors and rounding.

I don't remember it to be especially difficult to use, but I guess
another one more C++ oriented would be CGAL.
