CGAL 5.1 - 3D Alpha Shapes
FixedAlphaShapeVertex_3 Class Reference

#include <Concepts/FixedAlphaShapeVertex_3.h>

Definition

The concept FixedAlphaShapeVertex_3 describes the requirements for the base vertex of a alpha shape with a fixed value alpha.

Refines:

TriangulationVertexBase_3, if the underlying triangulation of the alpha shape is a Delaunay triangulation.

RegularTriangulationVertexBase_3, if the underlying triangulation of the alpha shape is a regular triangulation.

Periodic_3TriangulationDSVertexBase_3, if the underlying triangulation of the alpha shape is a periodic triangulation.

Has Models:
CGAL::Fixed_alpha_shape_vertex_base_3 (templated with the appropriate triangulation vertex base class).
