#include <CGAL/Triangulation_cell_base_with_circumcenter_3.h>

Inherits from

TriangulationCellBase_3.

Definition

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.

Template Parameters
DelaunayTriangulationTraits_3is the geometric traits class.
TriangulationCellBase_3is a cell base class from which Triangulation_cell_base_with_circumcenter_3 derives. It has the default value Triangulation_cell_base_3<DelaunayTriangulationTraits_3>.
Is Model Of:
TriangulationCellBase_3

const
DelaunayTriangulationTraits_3::Point_3 & 		circumcenter (const DelaunayTriangulationTraits_3 &gt=DelaunayTriangulationTraits_3()) const
