read_STL() [1/2]

template<typename Graph , typename NamedParameters >

bool CGAL::IO::read_STL	(	std::istream &	is,
		Graph &	g,
		const NamedParameters &	np
	)

#include <CGAL/boost/graph/IO/STL.h>

reads the graph g from the input stream, using the STereoLithography (STL) File Format.

The data is expected to represent a 2-manifold (possibly with borders).

Attention

The graph g 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

Graph	a model of MutableFaceGraph
NamedParameters	a sequence of Named Parameters

Parameters

is	the input stream
g	the graph to be built from the input data
np	optional Named Parameters described below

Optional Named Parameters

vertex_point_map a property map associating points to the vertices of g Type: a class model of WritablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type Default: boost::get(CGAL::vertex_point, g) Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in Graph.
verbose whether extra information is printed when an incident occurs during reading Type: Boolean Default: false

Returns

true if reading was successful and the resulting mesh is valid, false otherwise.

read_STL() [2/2]

template<typename Graph , typename NamedParameters >

bool CGAL::IO::read_STL	(	const std::string &	fname,
		Graph &	g,
		const NamedParameters &	np
	)

#include <CGAL/boost/graph/IO/STL.h>

reads the graph g from the file fname, using the STereoLithography (STL) File Format.

The data is expected to represent a 2-manifold (possibly with borders). If use_binary_mode is true, but the reading fails, ASCII reading will be automatically tested.

Attention

The graph g is not cleared, and the data from the file are appended.

Template Parameters

Graph	a model of MutableFaceGraph
NamedParameters	a sequence of Named Parameters

Parameters

fname	the name of the input file
g	the graph to be built from the input data
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
vertex_point_map a property map associating points to the vertices of g Type: a class model of WritablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type Default: boost::get(CGAL::vertex_point, g) Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in Graph.
verbose whether extra information is printed when an incident occurs during reading Type: Boolean Default: false

Returns

true if reading was successful and the resulting mesh is valid, false otherwise.

write_STL() [1/2]

template<typename Graph , typename NamedParameters >

bool CGAL::IO::write_STL	(	std::ostream &	os,
		const Graph &	g,
		const NamedParameters &	np
	)

#include <CGAL/boost/graph/IO/STL.h>

writes the graph g in the output stream 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

Graph	a model of FaceListGraph and HalfedgeListGraph
NamedParameters	a sequence of Named Parameters

Parameters

os	the output stream
g	the graph to be written
np	optional Named Parameters described below

Optional Named Parameters

vertex_point_map a property map associating points to the vertices of g Type: a class model of ReadablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type Default: boost::get(CGAL::vertex_point, g) Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in Graph.
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 streamos`` Extra: This parameter is only meaningful while using ASCII encoding.

Precondition

The graph must contain only triangle faces.

Returns

true if writing was successful, false otherwise.

write_STL() [2/2]

template<typename Graph , typename NamedParameters >

bool CGAL::IO::write_STL	(	const std::string &	fname,
		const Graph &	g,
		const NamedParameters &	np
	)

#include <CGAL/boost/graph/IO/STL.h>

writes the graph g into a file named fname, using the STereoLithography (STL) File Format.

Template Parameters

Graph	a model of FaceListGraph and HalfedgeListGraph
NamedParameters	a sequence of Named Parameters

Parameters

fname	the name of the output stream
g	the graph to be written
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
vertex_point_map a property map associating points to the vertices of g Type: a class model of WritablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type Default: boost::get(CGAL::vertex_point, g) Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in Graph.
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.

Precondition

The graph must contain only triangle faces.

Returns

true if writing was successful, false otherwise.
