Definition

The concept PolylinesDataStructure describes the way the curves on the mesh will be accessed.

See also: CGAL::Mesh_smoothing_3::Mesh_smoother; MeshDataStructure; SurfaceDataStructure

Types
using	Edge_descriptor = unspecified_type
	Descriptor used to access a edge information.
using	Curve_index = unspecified_type
	Index associated with an edge to identify the curve it belongs to.
using	Vertex_descriptor = unspecified_type
	Descriptor used to access a vertex information.

Operations
The following functions are used to access surface data:
std::size_t	nb_edges () const
	std::size_t is optional but will avoid warnings.
unspecified_type	edge_range () const
	Provides an iterable range over the Edge_descriptor of the mesh.
Curve_index	curve_id (Edge_descriptor edge) const
	Returns an identifier (curve id, segment id, ...) related to an edge.
Vertex_descriptor	edge_vertex (Edge_descriptor edge, unsigned i) const
	Return the ith vertex of an edge (max 2).

Member Typedef Documentation

Index associated with an edge to identify the curve it belongs to.

This is used to query the curve information from the user.

Descriptor used to access a vertex information.

Must be compatible with the one used in MeshDataStructure.
