◆ read_off() [1/2]

template<typename FaceGraph , typename NamedParameters >
bool CGAL::read_off ( std::istream &  is,
FaceGraph &  g,
NamedParameters  np 
)

#include <CGAL/boost/graph/io.h>

reads the graph g from data in the OFF format.

Ignores comment lines which start with a hash, and lines with whitespace.

Named Parameters
vertex_point_mapthe property map with the points associated to the vertices of g. If this parameter is omitted, an internal property map for CGAL::vertex_point_t should be available in FaceGraph
See also
Overloads of this function for specific models of the concept FaceGraph.
Precondition
The data must represent a 2-manifold
Attention
The graph g is not cleared, and the data from the stream are added.

◆ read_off() [2/2]

template<typename FaceGraph , typename NamedParameters >
bool CGAL::read_off ( const char *  fname,
FaceGraph &  g,
NamedParameters  np 
)

#include <CGAL/boost/graph/io.h>

reads the graph g from data in the OFF format.

Ignores comment lines which start with a hash, and lines with whitespace.

writes the graph g in the OFF format.

Named Parameters
vertex_point_mapthe property map with the points associated to the vertices of g. If this parameter is omitted, an internal property map for CGAL::vertex_point_t should be available in FaceGraph

template<typename FaceGraph , typename NamedParameters >
bool CGAL::write_off ( const char *  fname,
const FaceGraph &  g,
const NamedParameters &  np 
)

#include <CGAL/boost/graph/io.h>

writes the graph g in the OFF format into a file named fname.

◆ write_vtp()

template<class TriangleMesh , class NamedParameters >
void CGAL::write_vtp ( std::ostream &  os,
const TriangleMesh &  mesh,
const NamedParameters &  np 
)

#include <CGAL/boost/graph/io.h>

writes a triangulated surface mesh in the PolyData XML format.

Template Parameters
TriangleMesha model of FaceListGraph with only triangle faces.
NamedParametersa sequence of Named Parameters
Parameters
osthe stream used for writing.
meshthe triangle mesh to be written.
npoptional sequence of Named Parameters among the ones listed below
Named Parameters
use_binary_modea Boolean indicating if the data should be written in binary (true, the default) or in ASCII (false).
vertex_point_mapthe property map with the points associated to the vertices of mesh. If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in TriangleMesh.
