Definition

The concept FixedAlphaShapeCell_3 describes the requirements for the base cell of a alpha shape with a fixed value alpha.

TriangulationCellBase_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::Fixed_alpha_shape_cell_base_3 (templated with the appropriate triangulation cell base class).
