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

Definition

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

Creation

template<typename ECM >
template<typename Profile , typename T >
optional<typename Profile::FT> CGAL::Surface_mesh_simplification::Edge_length_cost< ECM >::operator() ( Profile const &  profile,
T const &  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 placement argument is ignored.
