CGAL::Convex_hull_traits_3< R, PolygonMesh > Class Template Reference

#include <CGAL/Convex_hull_traits_3.h>

Definition

template<typename R, typename PolygonMesh = Polyhedron_3<R>>
class CGAL::Convex_hull_traits_3< R, PolygonMesh >

The class Convex_hull_traits_3 serves as a traits class for the function convex_hull_3().

This is the default traits class for this function when R is a kernel with exact predicates but inexact constructions (note that the type Plane_3 is a triple of Point_3 and not R::Plane_3).

Template Parameters

PolygonMesh

must be a model of the concept MutableFaceGraph.

Is Model Of:

ConvexHullTraits_3

IsStronglyConvexTraits_3

Attention

The user must include the header file of the polygon mesh type, even for the default type.

Advanced

This class has a fourth undocumented template argument. Passing CGAL::Tag_false switches off a caching of a plane with coordinates with interval arithmetic. Instead an orientation test of four points is performed.
