Cb.
The class Regular_triangulation_cell_base_with_weighted_circumcenter_3 derives from Cb, a cell base class of a 3D triangulation.
It is the default cell base class of regular triangulations.
| Traits | is the geometric traits class. It must be a model of RegularTriangulationTraits_3. |
| Cb | is a cell base class from which Regular_triangulation_cell_base_3 derives. It must be a model of TriangulationCellBase_3. By default, this parameter is instantiated by Triangulation_cell_base_3<Traits>. |
RegularTriangulationCellBase_3 Types | |

Hidden points-related functions | |
Not every weighted point inserted in a regular triangulation necessarily appears in the triangulation. If the weight of a point is too small compared to other points, it might be hidden. These hidden vertices are stored in a unique corresponding cell (defined through v->cell()). The following functions provide set and get functionalities. | |
| Point_iterator | hidden_points_begin () |
| Returns an iterator pointing to the first hidden point. | |
| Point_iterator | hidden_points_end () |
| Returns a past-the-end iterator. | |
| void | hide_point (const Point &p) |
Adds p to the set of hidden points of the cell. | |
| const Point_3 & | weighted_circumcenter (const Traits >=Traits()) const |
| Returns the weighted circumcenter of the cell. | |
| const Point_3 & CGAL::Regular_triangulation_cell_base_3< Traits, Cb >::weighted_circumcenter | ( | const Traits & | gt = Traits() | ) | const |
Returns the weighted circumcenter of the cell.
Be careful that the return type is Point_3, and the radius of the weighted circumcenter is not supposed to be computed by the constructor Construct_weighted_circumcenter_3 of the traits class, hence the returned point has no weight.
