FixedAlphaShapeVertex_3 Concept Reference
Concepts

Definition

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

Refines:
TriangulationVertexBase_3
Has Models:
CGAL::Fixed_alpha_shape_vertex_base_3

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.
