template<class PolygonMesh, class VPMap = typename boost::property_map<PolygonMesh, CGAL::vertex_point_t>::const_type>
class CGAL::Polygon_mesh_processing::Adaptive_sizing_field< PolygonMesh, VPMap >

A sizing field describing variable target mesh edge lengths for CGAL::Polygon_mesh_processing::isotropic_remeshing().

This adaptive sizing field is a function of local discrete curvatures, computed using the CGAL::Polygon_mesh_processing::interpolated_corrected_curvatures() function.

Edges too long with respect to the local target edge length are split in two, while edges that are too short are collapsed.

This class depends on the Eigen library.

Is model of: PMPSizingField

See also: isotropic_remeshing(); Uniform_sizing_field

Template Parameters

PolygonMesh model of MutableFaceGraph that has an internal property map for CGAL::vertex_point_t.

Examples: PMP_Remeshing/isotropic_remeshing_with_sizing_example.cpp.

Constructor.

Template Parameters

FaceRange	range of `boost::graph_traits<PolygonMesh>::face_descriptor`, model of `Range`. Its iterator type is `ForwardIterator`.
NamedParameters	a sequence of Named Parameters

Parameters

tol	the error tolerance, used together with curvature to derive target edge length. Lower tolerance values will result in shorter mesh edges.
edge_len_min_max	contains the bounds for minimum and maximum edge lengths
face_range	the range of triangular faces defining one or several surface patches to be remeshed. It should be the same as the range of faces passed to `isotropic_remeshing()`.
pmesh	a polygon mesh with triangulated surface patches to be remeshed. It should be the same mesh as the one passed to `isotropic_remeshing()`.
np	an optional sequence of Named Parameters among the ones listed below

Optional Named Parameters

a property map associating points to the vertices of pmesh
Type: a class model of ReadWritePropertyMap with boost::graph_traits<PolygonMesh>::vertex_descriptor as key type and Point_3 as value type
Default: boost::get(CGAL::vertex_point, pmesh)
Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in PolygonMesh.

ball_radius parameter passed to interpolated_corrected_curvatures()
