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

First  CGAL::Triangulation_euclidean_traits_xy_3 is deprecated,
you should use Projection_traits_xy_3 instead.

http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Kernel_23_ref/Class_Projection_traits_xy_3.htm

Then replace K by Triangulation_traits in vertex and face instantiation
and that should work.

Sebastien.
