Cb.
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.
Traits | is the geometric traits class and must be a model of TriangulationTraits_3 . |
Cb | is 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<Traits> . |
