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

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

Definition

template<typename TriangleMesh>
class CGAL::Surface_mesh_simplification::Edge_length_cost< TriangleMesh >

The class Edge_length_cost is a model for the GetCost concept, which computes the collapse cost as the squared length of the edge.

Template Parameters

TriangleMesh

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

Is model of

GetCost

Creation
	Edge_length_cost ()
	Default constructor

Operations
std::optional< typename Edge_profile::FT >	operator() (const Edge_profile &profile, const std::optional< typename Edge_profile::Point > &placement) const
	Returns the collapse cost as the squared distance between the points of the source and target vertices (that is, profile.p0() and profile.p1().

Member Function Documentation

template<typename TriangleMesh >

std::optional< typename Edge_profile::FT > CGAL::Surface_mesh_simplification::Edge_length_cost< TriangleMesh >::operator()	(	const Edge_profile &	profile,
		const std::optional< typename Edge_profile::Point > &	placement
	)		const

Returns the collapse cost as the squared distance between the points of the source and target vertices (that is, profile.p0() and profile.p1().

The argument placement is unused.
