◆ 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.
