Definition

The base cell of a Delaunay triangulation has to be a model of the concept DelaunayTriangulationCellBase_3, which refines the concept TriangulationCellBase_3 by adding in the cell an operator that computes its circumcenter.

Refines:
TriangulationCellBase_3
Has Models:

CGAL::Delaunay_triangulation_cell_base_3

CGAL::Delaunay_triangulation_cell_base_with_circumcenter_3

Member Function Documentation

const DelaunayTriangulationTraits_3::Point_3& DelaunayTriangulationCellBase_3::circumcenter ( const DelaunayTriangulationTraits_3 &  gt = DelaunayTriangulationTraits_3()) const

Returns the circumcenter of the cell.

DelaunayTriangulationTraits_3 is the geometric traits class of the triangulation.

This operator is required only when the dual functions are called.
