CGAL 5.3  3D Mesh Generation

#include <CGAL/Mesh_vertex_base_3.h>
Vb.
The class Mesh_vertex_base_3
is a model of the concept MeshVertexBase_3
.
It is designed to serve as vertex base class for the 3D triangulation used in a 3D mesh generation process.
Gt  is the geometric traits class. It must be a model of the concept MeshTriangulationTraits_3 . 
MD  provides the types of indices used to identify the faces of the input complex. It must be a model of the concept MeshDomain_3 . 
Vb  is the vertex base class. It has to be a model of the concept RegularTriangulationVertexBase_3 and defaults to Regular_triangulation_vertex_base_3<Gt> .
