#include <CGAL/Regular_triangulation_cell_base_with_weighted_circumcenter_3.h>
Cb.
The class Regular_triangulation_cell_base_with_weighted_circumcenter_3
derives from Cb
, a cell base class of a 3D triangulation.
It provides an easy way to cache the computation of the weighted circumcenters of tetrahedra. Note that input/output operators discard this additional information.
All functions modifying the vertices of the cell invalidate the cached circumcenter.
Traits | is the geometric traits class and must be a model of RegularTriangulationTraits_3 . |
Cb | is a cell base class from which Regular_triangulation_cell_base_with_weighted_circumcenter_3 derives. Cb should be a model of RegularTriangulationCellBase_3 . It has the default value Regular_triangulation_cell_base_3<RT> . |
