read_OFF() [1/2]

template<typename OutputIteratorValueType , typename PointOutputIterator , typename NamedParameters = CGAL::parameters::Default_named_parameters>

bool CGAL::IO::read_OFF	(	const std::string &	fname,
		PointOutputIterator	output,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/read_off_points.h>

reads points (positions + normals, if available), using the IOStreamOFF.

Template Parameters

OutputIteratorValueType	type of objects that can be put in PointOutputIterator. It must be a model of DefaultConstructible and defaults to value_type_traits<PointOutputIterator>::type. It can be omitted when the default is fine.
PointOutputIterator	iterator over output points.
NamedParameters	a sequence of Named Parameters

Parameters

fname	input file name
output	output iterator over points
np	optional sequence of Named Parameters among the ones listed below.

Optional Named Parameters

point_map a property map associating points to the elements of the point range Type: a model of WritablePropertyMap with value type geom_traits::Point_3 Default: CGAL::Identity_property_map<geom_traits::Point_3>
normal_map a property map associating normals to the elements of the point range Type: a model of WritablePropertyMap with value type geom_traits::Vector_3 Default: If this parameter is omitted, normals in the input stream are ignored.
geom_traits an instance of a geometric traits class Type: a model of Kernel Default: a CGAL Kernel deduced from the point type, using CGAL::Kernel_traits

Returns

true if reading was successful, false otherwise.

points	input point range
np	an optional sequence of Named Parameters among the ones listed below

Optional Named Parameters

point_map a property map associating points to the elements of the point range Type: a model of ReadablePropertyMap with value type geom_traits::Point_3 Default: CGAL::Identity_property_map<geom_traits::Point_3>

geom_traits an instance of a geometric traits class Type: a model of Kernel Default: a CGAL Kernel deduced from the point type, using CGAL::Kernel_traits
stream_precision a parameter used to set the precision (i.e. how many digits are generated) of the output stream Type: int Default: 6

Returns

true if writing was successful, false otherwise.
