CGAL 4.12 - Triangulated Surface Mesh Simplification
CGAL::Surface_mesh_simplification::LindstromTurk_cost< ECM > Class Template Reference

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


The class LindstromTurk_cost provides a model for the GetCost concept.

It computes the collapse cost following the Lindstrom-Turk strategy (Section Lindstrom-Turk Cost and Placement Strategy)

Template Parameters
