CGAL 5.1  3D Triangulation Data Structure

#include <CGAL/Triangulation_ds_vertex_base_3.h>
The class Triangulation_ds_vertex_base_3
can be used as the base vertex for a 3Dtriangulation data structure, it is a model of the concept TriangulationDSVertexBase_3
.
Note that if the triangulation data structure is used as a parameter of a geometric triangulation (Section Software Design and Chapter 3D Triangulations), then the vertex base class has to fulfill additional geometric requirements, i.e. it has to be a model of the concept TriangulationVertexBase_3
.
This base class can be used directly or can serve as a base to derive other base classes with some additional attributes (a color for example) tuned for a specific application.
