CGAL 4.14.2  3D Triangulations

#include <CGAL/Triangulation_cell_base_3.h>
TDSCb.
The class Triangulation_cell_base_3
is a model of the concept TriangulationCellBase_3
, the base cell of a 3Dtriangulation.
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 . It is actually not used by this class. 
TDSCb  is a combinatorial cell base class from which Triangulation_cell_base_3 derives. It must be a model of the TriangulationDSCellBase_3 concept. It has the default value Triangulation_ds_cell_base_3 .
