CGAL::Surface_mesh_simplification::Edge_length_stop_predicate< FT > Class Template Reference

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

Definition

template<typename FT>
class CGAL::Surface_mesh_simplification::Edge_length_stop_predicate< FT >

The class Edge_length_stop_predicate is a model for the StopPredicate concept, which returns true when the top edge in the priority queue is larger than a certain threshold.

This predicate is meant to be used with Edge_length_cost.

Template Parameters

FT	is the number type of the point coordinates, and must be equal to Edge_profile::FT.

Is model of

StopPredicate

Examples

Surface_mesh_simplification/edge_collapse_all_short_edges.cpp.

Creation
	Edge_length_stop_predicate (const Edge_profile::FT threshold)
	Initializes the predicate establishing the threshold value.

Operations
bool	operator() (const Edge_profile::FT &, 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 (CGAL::squared_distance(edge_profile.p0(),edge_profile.p1()) > threshold*threshold).

template<typename FT >

bool CGAL::Surface_mesh_simplification::Edge_length_stop_predicate< FT >::operator()	(	const Edge_profile::FT &	,
		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 (CGAL::squared_distance(edge_profile.p0(),edge_profile.p1()) > threshold*threshold).

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