Definition

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

a sizing field describing a uniform target edge length for CGAL::Polygon_mesh_processing::isotropic_remeshing().

Edges longer than 4/3 of the target edge length will be split in half, while edges shorter than 4/5 of the target edge length will be collapsed.

Template Parameters

PolygonMesh	model of MutableFaceGraph that has an internal property map for CGAL::vertex_point_t.
VPMap	property map associating points to the vertices of pmesh, model of ReadWritePropertyMap with boost::graph_traits<PolygonMesh>::vertex_descriptor as key type and Point_3 as value type. Default is boost::get(CGAL::vertex_point, pmesh).

Constructor & Destructor Documentation

Uniform_sizing_field() [1/2]

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

CGAL::Polygon_mesh_processing::Uniform_sizing_field< PolygonMesh, VPMap >::Uniform_sizing_field	(	const FT	size,
		const VPMap &	vpmap
	)

Constructor.

Parameters

size	the target edge length for isotropic remeshing. If set to 0, the criterion for edge length is ignored and edges are neither split nor collapsed.
vpmap	is the input vertex point map that associates points to the vertices of the input mesh.

Uniform_sizing_field() [2/2]

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

CGAL::Polygon_mesh_processing::Uniform_sizing_field< PolygonMesh, VPMap >::Uniform_sizing_field	(	const FT	size,
		const PolygonMesh &	pmesh
	)

Constructor using internal vertex point map of the input polygon mesh.

Parameters

size	the target edge length for isotropic remeshing. If set to 0, the criterion for edge length is ignored and edges are neither split nor collapsed.
pmesh	a polygon mesh with triangulated surface patches to be remeshed. The default vertex point map of pmesh is used to construct the class.
