#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Count_ratio_stop_predicate.h>

Definition

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

Template Parameters
ECMis the type of surface mesh being simplified, and must be a model of the EdgeCollapsableSurfaceMesh concept.
Is Model Of:
StopPredicate

Creation

 Count_ratio_stop_predicate (double ratio)
 Initializes the predicate establishing the ratio.
 

Operations

bool operator() (FT const &current_cost, Profile const &edge_profile, size_type initial_count, size_type current_count) const
 Returns ( ((double)current_count / (double)initial_count) < ratio). More...
