The class Triangulation_cell_base_with_circumcenter_3 is a model of the concept TriangulationCellBase_3, the base cell of a 3D-triangulation. It provides an easy way to cache the computation of the circumcenter of tetrahedra. Note that input/output operators discard this additional information.
All functions modifying the vertices of the cell, invalidate the cached circumcenter.
#include <CGAL/Triangulation_cell_base_with_circumcenter_3.h>
The first template argument is the geometric traits class DelaunayTriangulationTraits_3.
The second template argument is a cell base class from which Triangulation_cell_base_with_circumcenter_3 derives. It has the default value Triangulation_cell_base_3<DelaunayTriangulationTraits_3>.
