auto SFCGAL::io::OBJ::createGeometryFromObjData ( const ObjData & obj_data ) -> std::unique_ptr<Geometry>

Create geometry from parsed OBJ data.

Parameters

[in] obj_data Parsed OBJ data

Returns: Geometry created from OBJ data

Exceptions

SFCGAL::Exception If geometry creation fails

SFCGAL_API auto SFCGAL::io::OBJ::load ( std::istream & inOBJ ) -> std::unique_ptr< Geometry >

Loads a geometry from an OBJ format stream.

Parameters

SFCGAL_API auto SFCGAL::io::OBJ::load ( const std::string & obj ) -> std::unique_ptr< Geometry >

Loads a geometry from an OBJ format string.

Parameters

[in] obj The OBJ format string

Returns: The loaded geometry

Exceptions

SFCGAL::Exception If the string is invalid or contains unsupported features

SFCGAL_API auto SFCGAL::io::OBJ::loadFromFile ( const std::filesystem::path & filename ) -> std::unique_ptr< Geometry >

Loads a geometry from an OBJ file.

Parameters

[in] filename The name of the file to load from

Returns: The loaded geometry

Exceptions

SFCGAL::Exception If the file cannot be opened or is invalid

auto SFCGAL::io::OBJ::parseObjData ( std::istream & inOBJ ) -> ObjData

Parse OBJ data from input stream.

Parameters

[in] inOBJ Input stream containing OBJ data

Returns: Parsed OBJ data

Exceptions

SFCGAL::Exception If parsing fails

SFCGAL_API void SFCGAL::io::OBJ::save	(	const Geometry &	geom,
		std::ostream &	out
	)

Saves a geometry to an OBJ format stream.

Parameters

[in]	geom	The geometry to save
[out]	out	The output stream

Exceptions

SFCGAL::Exception If the geometry is invalid or unsupported

SFCGAL_API void SFCGAL::io::OBJ::save	(	const Geometry &	geom,
		const std::string &	filename
	)

Saves a geometry to an OBJ file.

Parameters

[in]	geom	The geometry to save
[in]	filename	The name of the file to save to

Exceptions

SFCGAL::Exception If the file cannot be opened or the geometry is invalid

SFCGAL_API void SFCGAL::io::OBJ::saveToBuffer	(	const Geometry &	geom,
		char *	buffer,
		size_t *	size
	)

Saves a geometry to an OBJ format buffer (C API).

Parameters

[in]	geom	The geometry to save
[out]	buffer	The buffer to write to
[in,out]	size	On input, the size of the buffer. On output, the number of bytes written (or required if buffer is null)

Exceptions

SFCGAL::Exception If the geometry is invalid or unsupported

SFCGAL_API auto SFCGAL::io::OBJ::saveToString ( const Geometry & geom ) -> std::string

Saves a geometry to an OBJ format string.

Parameters

[in] geom The geometry to save

Returns: The OBJ format string

Exceptions

SFCGAL::Exception If the geometry is invalid or unsupported
