CGAL::Projection_traits_3< K > Class Template Reference

#include <CGAL/Projection_traits_3.h>

Definition

The class Projection_traits_3 works similarly to the Projection_traits_xy_3, Projection_traits_xz_3, and Projection_traits_yz_3 traits classes, enabling the use of 2D algorithms on the projections of 3D data onto an arbitrary plane.

Template Parameters

K	must be a model of Kernel

Note

Internal constructions (projections) are used in the predicate and construction functors of this class. If K is a model of Kernel providing exact constructions or if K is a CGAL::Filtered_kernel (such as for CGAL::Exact_predicates_inexact_constructions_kernel), this class automatically provides exact predicates.

Is Model Of:

TriangulationTraits_2

DelaunayTriangulationTraits_2

ConstrainedTriangulationTraits_2

PolygonTraits_2

Barycentric_coordinates::BarycentricTraits_2
