read_STL() [1/2]

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

bool CGAL::IO::read_STL	(	std::istream &	is,
		PointRange &	points,
		TriangleRange &	facets,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/STL.h>

reads the content of is into points and facets, using the STereoLithography (STL) File Format.

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
TriangleRange	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

is	the input stream
points	points of the soup of triangles
facets	a range of triangles; each triangle uses 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.

read_STL() [2/2]

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

bool CGAL::IO::read_STL	(	const std::string &	fname,
		PointRange &	points,
		TriangleRange &	facets,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/STL.h>

reads the content of a file named fname into points and facets, using the STereoLithography (STL) File Format.

If use_binary_mode is true, but the reading fails, ASCII reading will be automatically tested.

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.
TriangleRange	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 input file
points	points of the soup of triangles
facets	a range of triangles; each triangle uses 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_STL() [1/2]

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

bool CGAL::IO::write_STL	(	std::ostream &	os,
		const PointRange &	points,
		const TriangleRange &	facets,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/STL.h>

writes the content of points and facets in os, using the STereoLithography (STL) File Format.

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.
TriangleRange	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

os	the output stream
points	points of the soup of triangles
facets	a range of triangles; each triangle uses the indices of the points in points.
np	optional sequence of Named Parameters among the ones listed 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.

write_STL() [2/2]

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

bool CGAL::IO::write_STL	(	const std::string &	fname,
		const PointRange &	points,
		const TriangleRange &	facets,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/IO/STL.h>

writes the content of points and facets in a file named fname, using the STereoLithography (STL) File Format.

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.
TriangleRange	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 triangles
facets	a range of triangles; each triangle uses the indices of the points in points.
np	optional sequence of Named Parameters among the ones listed 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.
