bool CGAL::IO::read_OFF
(
std::istream &
is ,
Graph &
g ,
const NamedParameters &
np
)
#include <CGAL/boost/graph/IO/OFF.h>
reads the graph g from data in the input stream, using the Object File Format (OFF) .
The data is expected to represent a 2-manifold (possibly with borders).
This function reads the point property as well as vertex normals (NOFF), vertex and face colors (COFF), and texture vertex coordinates (TOFF). Those properties are stored in property maps that are passed through named parameters (see below), when passed.
Ignores comment lines which start with a hash, and lines with whitespace.
Attention The graph g is not cleared, and the data from the stream are appended. Template Parameters
Parameters

Default: face colors that may exist in the input will be ignored
verbose
whether extra information is printed when an incident occurs during reading
Type: Boolean
