Definition

Deprecated:
This class is deprecated since CGAL 4.4. The class Delaunay_triangulation_cell_base_with_circumcenter_3 should be used instead. Regular_triangulation_cell_base_with_weighted_circumcenter_3 and Triangulation_cell_base_with_info_3 can also be used in other frameworks.

The class 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
TriangulationTraits_3is the geometric traits class.
Cbis a cell base class from which Triangulation_cell_base_with_circumcenter_3 derives. Cb should be a model of TriangulationCellBase_3 or DelaunayTriangulationCellBase_3. It has the default value Triangulation_cell_base_3<DelaunayTriangulationTraits_3>.
Is Model Of:
TriangulationCellBase_3
