CGAL 4.13.2 - 3D Convex Hulls
CGAL::Extreme_points_traits_adapter_3< PointPropertyMap, Base_traits > Class Template Reference

#include <CGAL/Extreme_points_traits_adapter_3.h>

Definition

template<class PointPropertyMap, class Base_traits = Default>
class CGAL::Extreme_points_traits_adapter_3< PointPropertyMap, Base_traits >

The class Extreme_points_traits_adapter_3 serves as a traits class for the function extreme_points_3().

It permits the use of this function for accessing vertices, indices, or anything that can be used as key_type for PointPropertyMap.

Template Parameters
PointPropertyMapa model of ReadablePropertyMap with CGAL::Point_3 as value_type.
Base_traitsa model of ConvexHullTraits_3 and IsStronglyConvexTraits_3. If the kernel R of the points from PointPropertyMap is a kernel with exact predicates but inexact constructions (in practice we check R::Has_filtered_predicates_tag is Tag_true and R::FT is a floating point type), then the default traits class used is Convex_hull_traits_3<R>, and R otherwise.
Is Model Of:

ConvexHullTraits_3

IsStronglyConvexTraits_3
