CGAL 5.1 - 3D Alpha Shapes
AlphaShapeCell_3 Class Reference

#include <Concepts/AlphaShapeCell_3.h>

Definition

The concept AlphaShapeCell_3 describes the requirements for the base cell of an alpha shape.

Refines:

DelaunayTriangulationCellBase_3, if the underlying triangulation of the alpha shape is a Delaunay triangulation.

RegularTriangulationCellBase_3, if the underlying triangulation of the alpha shape is a regular triangulation.

Periodic_3TriangulationDSCellBase_3, if the underlying triangulation of the alpha shape is a periodic triangulation.

Has Models:
CGAL::Alpha_shape_cell_base_3 (templated with the appropriate triangulation cell base class).
