read_MEDIT()

template<class PointRange, class TetrahedronRange, typename NamedParameters = CGAL::parameters::Default_named_parameters>

bool CGAL::IO::read_MEDIT	(	std::istream &	is,
		PointRange &	points,
		TetrahedronRange &	tetrahedra,
		const NamedParameters &	np = parameters::default_values() )

#include <CGAL/IO/MEDIT.h>

reads the content of is into points and tetrahedra using the Medit File Format

Attention

The tetrahedron soup is not cleared, and the data from the stream are appended.

Template Parameters

PointRange	a model of the concept BackInsertionSequence whose value type is the point type
TetrahedronRange	a model of the concept BackInsertionSequence whose value_type is std::array<int,4>

Parameters

is	the input stream
points	points of the soup of cells
tetrahedra	each element in it describes a tetrahedron using the indices of the points in points
np	optional Named Parameters described below

Optional Named Parameters

subdomains a non-const reference wrapper to a container of integers that will be filled by this function. Each element in the container indicates the subdomain index of the corresponding tetrahedron at the same position. Type: a std::reference_wrapper to a model of BackInsertionSequence able to store int. Default: subdomains are ignored
facets_with_indices a non-const reference wrapper to a container of quadruples of integers that will be filled by this function. Each element represents a facet with vertices corresponding to the three first integers, and the last integer being the surface patch index of the facet. Type: a std::reference_wrapper to a model of BackInsertionSequence with a value type constructible using a braced initializer list of four integers. Default: facets are ignored
edges_with_indices a non-const reference wrapper to a container of triples of integers that will be filled by this function. Each element represents an edge with vertices corresponding to the two first integers, and the last integer being the curve index of the edge. Type: a std::reference_wrapper to a model of BackInsertionSequence with a value type constructible using a braced initializer list of three integers. Default: edges are ignored
corners_with_indices a non-const reference wrapper to a container of pair of integers that will be filled by this function. Each element represents a corner at the vertex corresponding to the first integer, and the last integer being the corner index. Type: a std::reference_wrapper to a model of BackInsertionSequence with a value type constructible using a braced initializer list of two integers. Default: corners are ignored
verbose if true, prints information about the reading process. Type: Boolean Default: false

Returns

true if the reading was successful, false otherwise.

write_MEDIT()

template<class PointRange, class TetrahedronRange, typename NamedParameters = CGAL::parameters::Default_named_parameters>

bool CGAL::IO::write_MEDIT	(	std::ostream &	os,
		const PointRange &	points,
		const TetrahedronRange &	tetrahedra,
		const NamedParameters &	np = parameters::default_values() )

#include <CGAL/IO/MEDIT.h>

writes the points and tetrahedra using the Medit File Format

Template Parameters

PointRange	a model of the concept ConstRange whose value type is the point type
TetrahedronRange	a model of the concept ConstRange whose value_type is a model of the concept RandomAccessContainer whose value_type is std::size_t.

Parameters

os	the output stream
points	points of the soup of cells
tetrahedra	each element in it describes a cell using the indices of the points in points
np	optional Named Parameters described below

Optional Named Parameters

subdomains a reference wrapper to a container of integers of the same size as tetrahedra. Each element in the container indicates the subdomain index of the corresponding tetrahedron at the same position. Type: a std::reference_wrapper to a model of the concept SequenceContainer of integer. Default: all tetrahedra will have the subdomain id 1.
facets_with_indices a const reference wrapper to a container of quadruples of integers that will be written by this function. Each element corresponds to a facet with vertices corresponding to the three first integers, and the last integer being the surface patch index of the facet. Type: a std::reference_wrapper to a model of SequenceContainer with a value type where the elements of the quadruples can be accessed with std::get<int>() Default: facets are ignored
edges_with_indices a const reference wrapper to a container of triples of integers that will be written by this function. Each element corresponds to an edge with vertices corresponding to the two first integers, and the last integer being the curve index of the edge. Type: a std::reference_wrapper to a model of SequenceContainer with a value type where the elements of the triples can be accessed with std::get<int>() Default: edges are ignored
corners_with_indices a const reference wrapper to a container of pair of integers that will be written by this function. Each element corresponds to a corner at the vertex corresponding to the first integer, the second integer being the corner index. As Medit has no notion of corner indices it is not written. Type: a std::reference_wrapper to a model of SequenceContainer with a value type where the elements of the pairs can be accessed with std::get<int>() Default: corners are ignored

Returns

true if the writing was successful, false otherwise.
