CGAL::Surface_mesh_simplification::GarlandHeckbert_policies< TriangleMesh, GeomTraits > Class Template Reference

#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/GarlandHeckbert_policies.h>

Definition

The class GarlandHeckbert_policies regroups the cost and placement policies based on the Garland-Heckbert strategy (Section Garland-Heckbert Cost and Placement Strategy), both oracles must indeed be used together as they internally use and share information associating quadrics to vertices.

Note however, that they may still be wrapped with slight behavior modifying classes such as Constrained_placement or Bounded_normal_change_placement.

Template Parameters

TriangleMesh	is the type of surface mesh being simplified, and must be a model of the MutableFaceGraph and HalfedgeListGraph concepts.
GeomTraits	must be a model of Kernel. If you have passed a traits class in the optional named parameters in the call to edge_collapse(), the types must be identical.

These policies depend on the third party Eigen library.

Public Types
typedef unspecified_type	Get_cost
	The type of the Garland Heckbert cost functor, a model of the concept GetCost
typedef unspecified_type	Get_placement
	The type of the Garland Heckbert placement functor, a model of the concept GetPlacement

Creation
	GarlandHeckbert_policies (Triangle_mesh &tmesh)
	Initializes the Garland-Heckbert policies.

Accessors
const Get_cost &	get_cost () const
const Get_placement &	get_placement () const
