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)

Types
typedef unspecified_type	Point
	Must be the same as the point type provided by the geometric traits class of the triangulation.

Creation
	FixedAlphaShapeVertex_3 ()
	default constructor.

	FixedAlphaShapeVertex_3 (Point p)
	constructor setting the point.

	FixedAlphaShapeVertex_3 (Point p, const Cell_handle &c)
	constructor setting the point and an incident cell.

Access Functions
bool	is_on_chull ()
	Returns a boolean indicating whether the point is on the convex hull of the point of the triangulation.

Classification_type	get_classification_type ()
	Returns the classification of the vertex.

Modifiers
void	set_classification_type (Classification_type type)
	Sets the classification of the vertex.

void	is_on_chull (bool b)
	Sets whether the vertex is on the convex hull.
