detects and constructs the feature graph from a surface

The feature graph has polylines that lie on the sharp features of the surface.

Template Parameters

Point_3	a model of Kernel::Point_3. It defines the feature graph point type.
PolygonMesh	a model of FaceListGraph that represents a surface mesh.

Parameters

pmesh

a polygon mesh from where the sharp features are extracted.

np

an optional sequence of Named Parameters among the ones listed below: Optional Named Parameters sharpness_estimator a functor model of SharpnessEstimator. See Sharpness Estimator for available functors. Default: CGAL::Feature_graph::Sharpness_estimator::Sharpness_estimator_on_surface(surface) regularization_parameters an instance of CGAL::Feature_graph::Regularization_parameters. It describes the parameters for the regularization step. Default: CGAL::Feature_graph::Regularization_parameters_on_surface() do_optimize a boolean indicating if the optimization step is called. Default: true optimization_parameters an instance of Optimization_parameters. It describe the parameters for the optimization step. Default: CGAL::Feature_graph::Optimization_parameters_on_surface<>() point_to_element_output_map an output property map that will be filled if supplied. It allows retrieving of the surface element where a feature graph point is embedded. It must be a model of WritablePropertyMap, so it must implement put(output_pmap, point_index, element_index) where the key type is the point index type of the feature graph, and the value type the element index type of the surface. The element index correspond to a facet element with the tag CGAL::DimensionTag<2> Default: parameters::default()

Returns

a graph model of VertexAndEdgeListGraph containing the constructed features.
