read_OFF() [1/2]

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

bool CGAL::IO::read_OFF	(	const std::string &	fname,
		PointRange &	points,
		PolygonRange &	polygons,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/OFF.h>

reads the content of the file fname into points and polygons, using the Object File Format (OFF).

Template Parameters

PointRange	a model of the concept RandomAccessContainer whose value type is the point type
PolygonRange	a model of the concepts SequenceContainer and BackInsertionSequence whose value_type is itself a model of the concept SequenceContainer and BackInsertionSequence whose value_type is an unsigned integer type convertible to std::size_t
NamedParameters	a sequence of Named Parameters

Parameters

fname	the path to the input file
points	points of the soup of polygons
polygons	a range of polygons. Each element in it describes a polygon using the indices of the points in points.
np	optional Named Parameters described below

Optional Named Parameters

verbose indicates whether output warnings and error messages should be printed or not. Type: Boolean Default: false

Returns

true if the reading was successful, false otherwise.
