CGAL 4.8.2 - 2D Convex Hulls and Extreme Points
|
#include <CGAL/convex_hull_constructive_traits_2.h>
The class Convex_hull_constructive_traits_2
serves as a traits class for all the two-dimensional convex hull and extreme point calculation function.
Unlike the class CGAL::Convex_hull_traits_2<R>
, this class makes use of previously computed results to avoid redundancy. For example, in the sidedness tests, lines (of type R::Line_2
) are constructed, which is equivalent to the precomputation of subdeterminants of the orientation-determinant for three points.
