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
TriangleMeshis 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::FToperator() (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().

◆ operator()()

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.
