I saw the example using Delaunay Triangulation 2.5D and everything works fine. Is it possible to use Conforming Delaunay Triangulation with CGAL::Projection_traits_xy_3? I'm trying using this setup: typedef CGAL::Exact_predicates_inexact_constructions_kernel K; typedef CGAL::Projection_traits_xy_3<K> Gt; typedef CGAL::Triangulation_vertex_base_with_info_2<std::string, Gt> Vb; typedef CGAL::Constrained_triangulation_face_base_2<Gt> Fb; typedef CGAL::Triangulation_data_structure_2<Vb, Fb> TDS; typedef CGAL::Exact_predicates_tag Itag; typedef CGAL::Constrained_Delaunay_triangulation_2<K, TDS, Itag> CDT; typedef K::Point_3 Point_CDT; I can't insert a Point_3 on a CDT. I tried using CGAL::No_intersection_tag to avoid create new points with no success. Is there a way to use Conforming Delaunay Triangulation 2.5D?

You have to use Gt instead of K on the cdt typedef typedef CGAL::Constrained_ I had trouble getting it to work thought with the exact tag. Use CDT::Point to get the point, its less errorprone. Cheers and gl! El dia 06/04/2017 11:39, "Pol M" <[hidden email]> va escriure:
