template<typename Traits>
class CGAL::Homological_discrete_vector_field::Mesh_object_io< Traits >

The class Mesh_object_io is an intermediate IO class, used to load triangular/tetraedral meshes and produce simplicial complexes.

Template Parameters

Traits a geometric traits class model of the HDVFTraits concept.

Constructor & Destructor Documentation

template<typename Traits >

CGAL::Homological_discrete_vector_field::Mesh_object_io< Traits >::Mesh_object_io	(	int	d,
		const std::vector< Point > &	vnodes,
		const std::vector< Io_cell_type > &	vcells,
		bool	sort_data = `false`
	)

Constructor from a vector of Point (vertex coordinates) and a vector of simplices.

Simplices are described by the list of vertex indices.

Parameters

d	The dimension `d` can be positive or negative: if positive: the set of simplicial cells loaded is a "mesh" and all cells have the same dimension if negative: the set of simplicial cells loaded have various dimensions and `d` must be the maximum of these dimensions.
vnodes	Vector of vertex coordinates.
vcells	Vector of cells (described by a sorted vector of indices)
sort_data	If `true` the vectors of vertex indices are sorted, if `false` they are assumed to be sorted (faster).
