I'm using CGAL::Triangulation_vertex_base_with_info_2 and I need to 
update its information with natural neighbor coordinates as triangulation are refined, is possible to do that with cgal?

Thanks,

Daniel

No. The CGAL 2D mesh generator¹ needs a bounded domain to work on. The
boundary of the domain must be given as constraints in a constrained Delaunay
triangulation. However, at the end of the meshing process, the constrained
Delaunay triangulation is guaranteed to be a conforming Delaunay
triangulation. In other words the constrained Delaunay triangulation is equal
to the Delaunay triangulation of its vertices. Maybe it is sufficient for your
needs.
