Function Documentation

wdb_fopen()

struct rt_wdb* wdb_fopen

(

const char *

filename

)

Routines to allow libwdb to use librt's import/export interface, rather than having to know about the database formats directly.

wdb_fopen_v()

struct rt_wdb* wdb_fopen_v	(	const char *	filename,
		int	version
	)

Create a libwdb output stream destined for a disk file. This will destroy any existing file by this name, and start fresh. The file is then opened in the normal "update" mode and an in-memory directory is built along the way, allowing retrievals and object replacements as needed.

The rt_wdb type returned is RT_WDB_TYPE_DB_DISK.

Users can change the database title by calling: ???

wdb_dbopen()

struct rt_wdb* wdb_dbopen	(	struct db_i *	dbip,
		int	mode
	)

Create a libwdb output stream destined for an existing BRL-CAD database, already opened via a db_open() call.

Note: there can be only one rt_wdb container of each type per dbip - if an rt_wdb of the specified type is already associated with the database, the pre-existing stream will be returned.

RT_WDB_TYPE_DB_DISK Add to on-disk database RT_WDB_TYPE_DB_DISK_APPEND_ONLY Add to on-disk database, don't clobber existing names, use prefix RT_WDB_TYPE_DB_INMEM Add to in-memory database only RT_WDB_TYPE_DB_INMEM_APPEND_ONLY Ditto, but give errors if name in use.

wdb_import()

int wdb_import	(	struct rt_wdb *	wdbp,
		struct rt_db_internal *	internp,
		const char *	name,
		const mat_t	mat
	)

Returns - 0 and modified *internp; -1 ft_import failure (from rt_db_get_internal) -2 db_get_external failure (from rt_db_get_internal) -3 Attempt to import from write-only (stream) file. -4 Name not found in database TOC.

NON-PARALLEL because of rt_uniresource

wdb_export_external()

int wdb_export_external	(	struct rt_wdb *	wdbp,
		struct bu_external *	ep,
		const char *	name,
		int	flags,
		unsigned char	minor_type
	)

The caller must free "ep".

Returns - 0 OK <0 error

wdb_put_internal()

int wdb_put_internal	(	struct rt_wdb *	wdbp,
		const char *	name,
		struct rt_db_internal *	ip,
		double	local2mm
	)

Convert the internal representation of a solid to the external one, and write it into the database.

The internal representation is always freed. This is the analog of rt_db_put_internal() for rt_wdb objects.

Use this routine in preference to wdb_export() whenever the caller already has an rt_db_internal structure handy.

NON-PARALLEL because of rt_uniresource

Returns - 0 OK <0 error

wdb_export()

int wdb_export	(	struct rt_wdb *	wdbp,
		const char *	name,
		void *	gp,
		int	id,
		double	local2mm
	)

Export an in-memory representation of an object, as described in the file h/rtgeom.h, into the indicated database.

The internal representation (gp) is always freed.

WARNING: The caller must be careful not to double-free gp, particularly if it's been extracted from an rt_db_internal, e.g. by passing intern.idb_ptr for gp.

If the caller has an rt_db_internal structure handy already, they should call wdb_put_internal() directly – this is a convenience routine intended primarily for internal use in LIBWDB.

Returns - 0 OK <0 error

wdb_init()

void wdb_init	(	struct rt_wdb *	wdbp,
		struct db_i *	dbip,
		int	mode
	)

wdb_close()

void wdb_close

(

struct rt_wdb *

wdbp

)

Close a database created with wdb_fopen or wdb_fopen_v.

wdb_import_from_path()

int wdb_import_from_path	(	struct bu_vls *	logstr,
		struct rt_db_internal *	ip,
		const char *	path,
		struct rt_wdb *	wdb
	)

Given the name of a database object or a full path to a leaf object, obtain the internal form of that leaf. Packaged separately mainly to make available nice Tcl error handling.

Returns - BRLCAD_OK BRLCAD_ERROR

wdb_import_from_path2()

int wdb_import_from_path2	(	struct bu_vls *	logstr,
		struct rt_db_internal *	ip,
		const char *	path,
		struct rt_wdb *	wdb,
		matp_t	matp
	)

Given the name of a database object or a full path to a leaf object, obtain the internal form of that leaf. Packaged separately mainly to make available nice Tcl error handling. Additionally, copies ts.ts_mat to matp.

Returns - BRLCAD_OK BRLCAD_ERROR
