GetCost Concept Reference
Concepts

Definition

The concept GetCost describes the requirements for the policy function object which gets the collapse cost of an edge.

The cost returned is a boost::optional value (i.e. it can be absent). An absent cost indicates that the edge should not be collapsed. This could be the result of a computational limitation (such as overflow), or can be intentionally returned to prevent the edge from being collapsed.

Has Models:

CGAL::Surface_mesh_simplification::Edge_length_cost<ECM>

CGAL::Surface_mesh_simplification::LindstromTurk_cost<ECM>

Types

typedef unspecified_type Profile
 The type of the edge profile cache. More...
 
typedef unspecified_type FT
 A field type representing the collapse cost.
 
CGAL::halfedge_graph_traits
< ECM >::Point 		Point
 The point type for the surface vertex. More...
 
boost::optional< FT > result_type
 The type of the result (an optional cost value).
 

Operations

result_type operator() (Profile const &edge_profile, boost::optional< Point > const &placement) const
 Computes and returns the cost of collapsing the edge (represented by its profile), using the calculated placement.
