Detailed Description

Interface structures and routines for libwdb.

Library for writing MGED database objects from arbitrary procedures. Assumes that some of the structure of such databases are known by the calling routines.

It is expected that this library will grow as experience is gained. Routines for writing every permissible solid do not yet exist.

Note that routines which are passed point_t or vect_t or mat_t parameters (which are call-by-address) must be VERY careful to leave those parameters unmodified (e.g., by scaling), so that the calling routine is not surprised.

Return codes of 0 are OK, -1 signal an error.

Note - Rather than using a stdio (FILE *), we now use a (struct rt_wdb *) parameter. Rather than calling fopen(), call wdb_fopen();

Function Documentation

◆ mk_id()

int mk_id	(	struct rt_wdb *	fp,
		const char *	title
	)

Make a database header (ID) record.

◆ mk_id_units()

int mk_id_units	(	struct rt_wdb *	fp,
		const char *	title,
		const char *	units
	)

Make a database header (ID) record, and note the user's preferred editing units (specified as a string).

Returns: <0 error, 0 success

◆ mk_id_editunits()

int mk_id_editunits	(	struct rt_wdb *	fp,
		const char *	title,
		double	local2mm
	)

Make a database header (ID) record, and note the user's preferred editing units (specified as a conversion factor).

Note that the v4 database format offers only a limited number of choices for the preferred editing units. If the user is editing in unusual units (like 2.5feet), don't fail to create the database header.

In the v5 database, the conversion factor will be stored intact.

Note that the database-layer header record will have already been written by db_create(). All we have to do here is update it.

Returns: <0 error, 0 success

Files can use a non-positive 'count' to mean "read the whole file", pre-loaded data, however, must provide a positive 'count' otherwise an empty binunif will be created.

◆ make_hole()

int make_hole	(	struct rt_wdb *	wdbp,
		point_t	hole_start,
		vect_t	hole_depth,
		fastf_t	hole_radius,
		int	num_objs,
		struct directory **	dp
	)

This routine is intended to be used to make a hole in some geometry.

The hole is described using the same parameters as an RCC, and the hole is represented as an RCC. The objects to be "holed" are passed in as a list of "struct directory" pointers. The objects pointed at by this list must be combinations. The "struct rt_wdb" pointer passed in indicates what model this hole should appear in.

The end state after this routine runs is a modified model with a new RCC primitive having a name of the form "make_hole_X" (where X is some integer). The combinations specified in the list will be modified as follows:

   before                          after
     |                              /\
     u                             u  -

orig_comb_tree orig_comb_tree make_hole_X

The modified combination is written to the struct rt_wdb. Note that to do dynamic geometry a "wdb_dbopen" would normally be called on an already existing (and possibly prepped) model. Using the RT_WDB_TYPE_DB_INMEM parameter in this call will result in geometry changes that only exist in memory and will not be permanently stored in the original database.

This routine should be preceded by a call to "rt_unprep" and followed by a call to "rt_reprep".

◆ make_hole_in_prepped_regions()

int make_hole_in_prepped_regions	(	struct rt_wdb *	wdbp,
		struct rt_i *	rtip,
		point_t	hole_start,
		vect_t	hole_depth,
		fastf_t	radius,
		struct bu_ptbl *	regions
	)

This routine provides a quick approach to simply adding a hole to existing prepped geometry.

The geometry must already be prepped prior to calling this routine. After calling this routine, the geometry is ready for raytracing (no other routine need to be called).

A new RCC primitive is created and written to the database (wdbp). Note that this will be temporary if the wdbp pointer was created by a call to wdb_dbopen with the RT_WDB_TYPE_DB_INMEM flag.

The "regions" parameter is a list of "struct region" pointers (prepped regions) to get holed. The regions structures are modified, but the on disk region records are never modified, so the actual holes will never be permanent regardless of how "wdbp" was opened.

There is no need to call "rt_unprep" nor "rt_reprep" with this routine.
