AlphaShapeVertex_3 Concept Reference

Definition

The concept AlphaShapeVertex_3 describes the requirements for the base vertex of an alpha shape.

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::Alpha_shape_vertex_base_3 (templated with the appropriate triangulation vertex base class)

CGAL::Alpha_status

Types
typedef unspecified_type	Point
	Must be the same as the point type provided by the geometric traits class of the triangulation.
typedef unspecified_type	Alpha_status
	Must be CGAL::Alpha_status<NT> where NT is the number type used in the geometric traits class of the triangulation.

Creation
	AlphaShapeVertex_3 ()
	default constructor.
	AlphaShapeVertex_3 (Point p)
	constructor setting the point.
	AlphaShapeVertex_3 (Point p, const Cell_handle &c)
	constructor setting the point and an incident cell.

Modifiers
Alpha_status *	get_alpha_status ()
	Returns a pointer the alpha status of the vertex.
