CGAL::Surface_mesh_simplification::Count_ratio_stop_predicate< TriangleMesh > Class Template Reference

#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

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

Is Model Of:

StopPredicate

Creation
	Count_ratio_stop_predicate (const double ratio)
	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 ((double)current_edge_count / (double)initial_edge_count) < ratio. More...

bool CGAL::Surface_mesh_simplification::Count_ratio_stop_predicate< TriangleMesh >::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 ((double)current_edge_count / (double)initial_edge_count) < ratio.

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