read_PLY() [1/2]

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

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

#include <CGAL/IO/PLY.h>

reads the content of fname into points and polygons, using the Polygon File Format (PLY).

Attention

The polygon soup is not cleared, and the data from the file are appended.

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 integer type
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

use_binary_mode indicates whether data should be read in binary (true) or in ASCII (false) Type: Boolean Default: true
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.

read_PLY() [2/2]

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

bool CGAL::IO::read_PLY	(	std::istream &	is,
		PointRange &	points,
		PolygonRange &	polygons,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/PLY.h>

reads the content of is into points and polygons, using the Polygon File Format (PLY).

Attention

The polygon soup is not cleared, and the data from the stream are appended.

To read a binary file, the flag std::ios::binary must be set during the creation of the ifstream.

Template Parameters

PointRange	a model of the concepts RandomAccessContainer and BackInsertionSequence 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

is	the input stream
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

use_binary_mode indicates whether data should be read in binary (true) or in ASCII (false) Type: Boolean Default: true
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.

write_PLY() [1/2]

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

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

#include <CGAL/IO/PLY.h>

writes the content of points and polygons in the file fname, using the Polygon File Format (PLY).

Template Parameters

PointRange	a model of the concept RandomAccessContainer whose value type is the point type
PolygonRange	a model of the concept SequenceContainer whose value_type is itself a model of the concept SequenceContainer 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 output 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

use_binary_mode indicates whether data should be written in binary (true) or in ASCII (false) Type: Boolean Default: true
stream_precision a parameter used to set the precision (i.e. how many digits are generated) of the output stream Type: int Default: 6 Extra: This parameter is only meaningful while using ASCII encoding.

Returns

true if the writing was successful, false otherwise.

write_PLY() [2/2]

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

bool CGAL::IO::write_PLY	(	std::ostream &	out,
		const PointRange &	points,
		const PolygonRange &	polygons,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/PLY.h>

writes the content of points and polygons in out, using the Polygon File Format (PLY).

Attention

To write to a binary file, the flag std::ios::binary must be set during the creation of the ofstream, and the IO::Mode of the stream must be set to BINARY.

Template Parameters

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

Parameters

out	the output stream
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

stream_precision a parameter used to set the precision (i.e. how many digits are generated) of the output stream Type: int Default: the precision of the stream os Extra: This parameter is only meaningful while using ASCII encoding.

Returns

true if the writing was successful, false otherwise.
