Greetings,

i am trying to make terrain triangulation which is also a constrained Delaunay triangulation. The instantiation  that I try is:

  typedef typename CGAL::Triangulation_vertex_base_2<Kernel>                                                                                               Vertex_base;
  typedef typename CGAL::Constrained_triangulation_face_base_2<Kernel>                                                                              Face_base;
  typedef typename CGAL::Triangulation_data_structure_2<Vertex_base,Face_base>                                                               Triangulation_structure;
  typedef typename CGAL::Triangulation_euclidean_traits_xy_3< Kernel >                                                                                  Triangulation_traits;
  typedef typename CGAL::Exact_predicates_tag                                                                                                                         Exact_tag;
  typedef typename CGAL::Constrained_Delaunay_triangulation_2<Triangulation_traits, Triangulation_structure, Exact_tag>  Triangulation;

but I get lots of compilation errors, instead if I try a simple Delaunay triangulation everything looks ok.

Any ideas on what I'm doing wrong?

thanks,

Constantinos
