Enumeration Type Documentation

enum CGAL::vertex_is_border_t

The constant vertex_is_border is a property tag which refers to the property of a vertex of being a border vertex.

vertex_is_border is an interior property, that is, a property map for vertex_is_border can be extracted from any model of a HalfedgeGraph using the Bgl PropertyGraph interface: boost::get(vertex_is_border,graph)

The Boolean flag that indicates if the vertex is a border can be directly accessed via: boost::get(vertex_is_border,graph,edge)

Enumerator
vertex_is_border

enum CGAL::vertex_point_t

The constant vertex_point is a property tag which refers to the geometric embedding property of a vertex of a HalfedgeGraph.

A vertex_point is an interior property, that is, a property map for a vertex_point can be extracted from any model of a HalfedgeGraph using the Bgl PropertyGraph interface: boost::get(vertex_point,graph)

A point of a vertex can be directly accessed via:

• boost::get(vertex_point,graph,vertex)
• boost::put(vertex_point,graph,vertex,newpoint)

Enumerator
vertex_point

		typename boost::graph_traits< HalfedgeGraph >::halfedge_descriptor	h
	)

Convenience function that calls triangle() with the property map obtained by get(CGAL::vertex_point, g).

template<typename HalfedgeGraph , typename PositionMap >

Kernel_traits<typename boost::property_traits<PositionMap>::value_type>::Kernel::Triangle_3 CGAL::triangle	(	const HalfedgeGraph &	g,
		typename boost::graph_traits< HalfedgeGraph >::halfedge_descriptor	h,
		const PositionMap &	pm
	)

triangle() returns a Triangle_3 constructed from the positions of the vertex_descriptors around the face incident to h in counter-clockwise direction.

The Kernel of the returned Triangle_3 is the same as the Kernel of the value_type of the.

Precondition

The face incident to h is triangular.

Template Parameters

PositionMap	must be a model of ReadablePropertyMap. Its value_type must be a model of Kernel::Point_3
HalfedgeGraph	must be a model of HalfedgeGraph.

Parameters

g	The graph
h	The halfedge
pm	The map used to find the vertices of the triangle.
