A Convex Hull Traits Class for the two-dimensional Kernel
(convex_hull_traits_2)

Definition

The class convex_hull_traits_2<R> is a convex hull traits class for the two-dimensional CGAL kernel, especially the two-dimensional point class. The class is parameterized with a representation class R. It is used in the default versions of the convex hull and extreme point algorithms.
