CGAL 5.4 - 2D Arrangements
|
The concept ArrangementBasicTopologyTraits
defines the minimal functionality needed for a model of a topology traits, which can substitutes the TopolTraits
template parameters when the class template Arrangement_on_surface_2<GeomTraits, TopolTraits>
is instantiated. In particular. a model of this concept holds the Dcel data structure used to represent the arrangement cells (i.e., vertices, edges, and facets) and the incident relations between them.
