CGAL users discussion list

i had the same problem, i solved it by using the incremental builder.

in my program, i need to re-triangulate triangles on a 3D surface. i
first do the triangulation in 2D. and then use the incremental builder
to create the same triangulation in 3D in the polyhedron_3 format. and
finally attach the re-triangulated piece to the original surface.

actually, i didn't use the triangulation feature of the CGAL, i used
another library. because in my case, the thing that needs to be
triangulated may be a concave polygon. i don't know how CGAL can do
the triangulation while preserving the concave border.
