Definition

template<typename GeomTraits, typename PolygonMesh, typename NeighborQuery, typename FaceRange = typename PolygonMesh::Face_range, typename VertexToPointMap = typename boost::property_map<PolygonMesh, CGAL::vertex_point_t>::type>
class CGAL::Shape_detection::Polygon_mesh::Least_squares_plane_fit_sorting< GeomTraits, PolygonMesh, NeighborQuery, FaceRange, VertexToPointMap >

Sorting of polygon mesh faces with respect to the local plane fit quality.

Indices of faces in a polygon mesh are sorted with respect to the quality of the least squares plane fit applied to the vertices of neighboring faces of each face.

Template Parameters

GeomTraits	must be a model of Kernel.
PolygonMesh	must be a model of FaceListGraph.
NeighborQuery	must be a model of NeighborQuery.
FaceRange	must be a model of ConstRange whose iterator type is RandomAccessIterator and value type is the face type of a polygon mesh.
VertexToPointMap	must be an LvaluePropertyMap whose key type is the vertex type of a polygon mesh and value type is Kernel::Point_3.

Examples:

Shape_detection/region_growing_planes_on_polygon_mesh.cpp.

Sorting
void	sort ()
	sorts indices of polygon mesh faces.

Access

Least_squares_plane_fit_sorting()

template<typename GeomTraits , typename PolygonMesh , typename NeighborQuery , typename FaceRange = typename PolygonMesh::Face_range, typename VertexToPointMap = typename boost::property_map<PolygonMesh, CGAL::vertex_point_t>::type>
