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

## Definition

template<typename TriangleMesh, typename GeomTraits>
class CGAL::Surface_mesh_simplification::GarlandHeckbert_policies< TriangleMesh, GeomTraits >

Deprecated:
  This class is deprecated since CGAL 5.5 and the introduction of variations of Garland-Heckbert policies (Section Garland-Heckbert Cost and Placement Strategy). The class `GarlandHeckbert_plane_policies` is the modern equivalent to this class.

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 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 (TriangleMesh &tmesh)
| Initializes the Garland-Heckbert policies.

## Accessors
const Get_cost & | get_cost () const
