`#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/LindstromTurk_placement.h>`

## Definition

The class `LindstromTurk_placement` provides a model for the `GetPlacement` concept.

It computes the placement, that is, the new position for the remaining vertex after a halfedge-collapse, following the Lindstrom-Turk strategy (Section Lindstrom-Turk Cost and Placement Strategy).

Template Parameters

  ECM | is the type of surface mesh being simplified, and must be a model of the `EdgeCollapsableSurfaceMesh` concept.

Is Model Of:
  `GetPlacement`
