Thank you The code I am using is as follows typedef CGAL::Delaunay_triangulation_3<K1> Triangulations; typedef Triangulations::Point Point_tr; typedef Triangulations::Facet Facet; typedef Triangulations::Finite_facets_iterator finite_facets_itr; typedef Triangulations::Triangle Triangle; list<finite_facets_itr> temp; Triangle temp_triangle; double temp_circumradius = 0; double temp_max_inter_vertice_dist; finite_facets_itr starting_facet = Tr.finite_facets_begin(); finite_facets_itr ending_facet = Tr.finite_facets_end(); finite_facets_itr current_facet = starting_facet; for(current_facet = starting_facet; current_facet != ending_facet; ++current_facet) { temp_triangle = Tr.triangle(*current_facet); if ( .......) { temp.push_back(current_facet); } } And I have attached in this email about the configuration of the machine I am using.
