CGAL 4.4 - Triangulated Surface Mesh Simplification
|
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.

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. More... | |
typedef unspecified_type GetCost::FT |
A field type representing the collapse cost.
typedef unspecified_type GetCost::Profile |
