New points will be added only if you have intersection between your constraints.

If you change the Itag of the Constrained_Delaunay_triangulation_2
class to CGAL::No_intersection_tag you will see an assertion when
an constraint intersect another one.

If you are not in this situation, please provide an minimal example showing the pb.

Sebastien.

Dear CGAL developers,

I construct a constrained Delaunay triangulation with a group of polygons,
the vertexes as input points and the edges as constraints. The polygons have
overlapped regions and edges. I find the result triangulation has vertexes
which are not from the input points. Is it a bug? How could i avoid this?

Many thanks.
