#include <CGAL/Delaunay_triangulation_cell_base_with_circumcenter_3.h>

Inherits from

Cb.

Definition

The class Delaunay_triangulation_cell_base_with_circumcenter_3 derives from Cb, a cell base class of a 3D triangulation.

It provides an easy way to cache the computation of the circumcenters 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.
Cbis a cell base class from which Delaunay_triangulation_cell_base_with_circumcenter_3 derives. Cb should be a model of DelaunayTriangulationCellBase_3. It has the default value Triangulation_cell_base_3<DelaunayTriangulationTraits_3>.
Is Model Of:
DelaunayTriangulationCellBase_3

Access function

As a model of the concept DelaunayTriangulationCellBase_3, Delaunay_triangulation_cell_base_3 provides a circumcenter() member fonction.

If it has already been computed in the past, the cached value is returned.

const Point_3 & circumcenter (const DelaunayTriangulationTraits_3 &gt=DelaunayTriangulationTraits_3()) const
 Computes the circumcenter of the tetrahedron, or retrieves it if already computed.
