CGAL users discussion list

[Edoardo Milotti <>]

I am using the following list of includes in a program that computes a hierarchical Delaunay triangulation 

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>

#include <CGAL/Delaunay_triangulation_3.h>

#include <CGAL/Triangulation_hierarchy_3.h>

#include <CGAL/Triangulation_vertex_base_with_info_3.h>

typedef CGAL::Exact_predicates_inexact_constructions_kernel K;

typedef CGAL::Triangulation_vertex_base_with_info_3<int, K> Vb;

typedef CGAL::Triangulation_hierarchy_vertex_base_3<Vb>  Vbh;

typedef CGAL::Triangulation_data_structure_3<Vbh>        Tds;

typedef CGAL::Delaunay_triangulation_3<K,Tds>            Dt;

typedef CGAL::Triangulation_hierarchy_3<Dt>              Dh;

typedef Dh::Finite_vertices_iterator Finite_vertices_iterator;

typedef Dh::Vertex_handle            Vertex_handle;

typedef Dh::Point                    Point;

Many variables are shadowed locally. Is this normal? Is it dangerous for program reliability? 

Thank you.
