The constant \ccc{vertex_point} is a \ccAnchor{http://www.boost.org/libs/graph/doc/PropertyTag.html}
{property tag} which refers to the  geometric embedding property of a  vertex of a \ccc{HalfedgeGraph}.

A \ccc{vertex_point} is an 
\ccAnchor{http://www.boost.org/libs/graph/doc/using_property_maps.html}
{interior property}, 
that is, a
\ccAnchor{http://www.boost.org/libs/property_map/PropertyMap.html}{property map} 
for a \ccc{vertex_point} can be extracted from any model of a \ccc{HalfedgeGraph}
using the {\sc Bgl}
\ccAnchor{http://www.boost.org/libs/graph/doc/PropertyGraph.html}
{PropertyGraph} interface:

\ccc{boost::get(vertex_point,graph)}

A point of a vertex can be directly accessed via:

\ccc{boost::get(vertex_point,graph,vertex)}\\
\ccc{boost::put(vertex_point,graph,vertex,newpoint)}
