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

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

Definition

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

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

TriangleMesh

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

Is model of

GetPlacement

Creation
	LindstromTurk_placement (const Edge_profile::FT &factor=FT(0.5))
	Initializes the policy with the given weighting unit factor.

Operations
std::optional< typename Edge_profile::Point >	operator() (const Edge_profile &profile) const
	Returns the new position for the remaining vertex after collapsing the edge (represented by its profile).
