Definition

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

The class GarlandHeckbert_plane_policies regroups the cost and placement policies based on the Garland-Heckbert "Classic Plane" strategy (Section Garland-Heckbert Cost and Placement Strategy).

This class implements the original Garland-Heckbert quadric error metric strategy, as described in their seminal paper [2].

Both the cost and the placement policies must 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.
