CGAL 4.14.3  3D Triangulations

#include <CGAL/Triangulation_vertex_base_3.h>
TDSVb.
The class Triangulation_vertex_base_3
is a model of the concept TriangulationVertexBase_3
, the base vertex of a 3Dtriangulation.
This class stores a point.
This class can be used directly or can serve as a base to derive other classes with some additional attributes (a color for example) tuned for a specific application.
Traits  is the geometric traits class and must be a model of TriangulationTraits_3 . Users of the geometric triangulations are strongly advised to use the same geometric traits class as the one used in Triangulation_3 . This way, the point type defined by the base vertex is the same as the point type defined by the geometric traits class. 
TDSVb  is a combinatorial vertex base class from which Triangulation_vertex_base_3 derives. It must be a model of the TriangulationDSVertexBase_3 concept. It has the default value Triangulation_ds_vertex_base_3<TDS> .
