CGAL 5.4 - 2D Convex Hulls and Extreme Points
CGAL::Convex_hull_traits_adapter_2< BaseTraits, PointPropertyMap > Class Template Reference

#include <CGAL/Convex_hull_traits_adapter_2.h>

Definition

The class Convex_hull_traits_adapter_2 serves as a traits class for all the two-dimensional convex hull and extreme point calculation functions.

Given a property map associating a key to a point, the class Convex_hull_traits_adapter_2 enables to compute the sequence of keys for which the associted points form a convex hull, performing the predicates of the base traits class on the points associated to the keys.

Is Model Of:
