Definition

Is Model Of:
StopPredicate

The class Face_count_ratio_stop_predicate is a model for the StopPredicate concept which returns true when the relation between the initial and current number of faces drops below a certain ratio.

Template Parameters
TriangleMeshis the type of surface mesh being simplified, and must be a model of the MutableFaceGraph and HalfedgeListGraph concepts.

Creation

 Face_count_ratio_stop_predicate (const double ratio, const TriangleMesh &tmesh)
 Initializes the predicate establishing the ratio.
 

Operations

bool operator() (const Edge_profile::FT current_cost, const Edge_profile &edge_profile, const Edge_profile::edges_size_type initial_edge_count, const Edge_profile::edges_size_type current_edge_count) const
 Returns true if the ratio of current face count over initial face count is strictly smaller than ratio, and false otherwise. More...

Returns true if the ratio of current face count over initial face count is strictly smaller than ratio, and false otherwise.

All other parameters are ignored (but exist since this is a generic policy).
