#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

ECM	is the type of surface mesh being simplified, and must be a model of the `EdgeCollapsableSurfaceMesh` concept.

Is Model Of:: StopPredicate

See Also: CGAL::Surface_mesh_simplification::Count_stop_predicate<ECM>

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...
