Enumeration Type Documentation

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 

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
PositionMapmust be a model of ReadablePropertyMap. Its value_type must be a model of Kernel::Point_3
HalfedgeGraphmust be a model of HalfedgeGraph.
Parameters
gThe graph
hThe halfedge
pmThe map used to find the vertices of the triangle.
