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.

Operations
The following functions are used to access surface data:
std::size_t	nb_edges () const
	Used only to reserve memory.
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 the given edge.
Vertex_descriptor	edge_vertex (Edge_descriptor edge, unsigned i) const
	Return the ith vertex of the 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.

Vertex_descriptor PolylinesDataStructure::edge_vertex	(	Edge_descriptor	edge,
		unsigned	i ) const

Return the ith vertex of the edge (max 2).

Vertex_descriptor as given in MeshDataStructure.

std::size_t PolylinesDataStructure::nb_edges ( ) const

Used only to reserve memory.

std::size_t is optional but will avoid warnings.
