## 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

See Also
  `DelaunayTriangulationTraits_3`

## Access functions
const DelaunayTriangulationTraits_3::Point_3 & | circumcenter (const DelaunayTriangulationTraits_3 &gt=DelaunayTriangulationTraits_3()) const
| Returns the circumcenter of the cell. More...

## 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.
