Definition

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

The class GarlandHeckbert_probabilistic_triangle_policies regroups the cost and placement policies based on the "Probabilistic Triangle" strategy of Trettner and Kobbelt [7].

This policy enhances the original Garland-Heckbert quadric error metrics, by adding notions of variance (i.e., noise) to the positions of the vertices and the normals of faces. Compared to the "classic" triangle strategy, this strategy sacrifices tightness to the input for speed and quality of the result (Section Garland-Heckbert Cost and Placement Strategy).

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.
