Function Documentation

rt_db_get_internal()

int rt_db_get_internal ( struct rt_db_internal *  ip, const struct directory *  dp, const struct db_i *  dbip, const mat_t  mat, struct resource *  resp  )

extern

Get an object from the database, and convert it into its internal (i.e., unserialized in-memory) representation. Applies the provided matrix transform only to the in-memory internal being returned.

Returns - <0 On error id On success.

rt_db_put_internal()

int rt_db_put_internal ( struct directory *  dp, struct db_i *  dbip, struct rt_db_internal *  ip, struct resource *  resp  )

extern

Convert the internal representation of a solid to the external one, and write it into the database. On success only, the internal representation is freed.

Returns - <0 error 0 success

rt_fwrite_internal()

int rt_fwrite_internal ( FILE *  fp, const char *  name, const struct rt_db_internal *  ip, double  conv2mm  )

extern

Put an object in internal format out onto a file in external format. Used by LIBWDB.

Can't really require a dbip parameter, as many callers won't have one.

THIS ROUTINE ONLY SUPPORTS WRITING V4 GEOMETRY.

Returns - 0 OK <0 error

rt_db_free_internal()

void rt_db_free_internal ( struct rt_db_internal *  ip )

extern

rt_db_lookup_internal()

int rt_db_lookup_internal ( struct db_i *  dbip, const char *  obj_name, struct directory **  dpp, struct rt_db_internal *  ip, int  noisy, struct resource *  resp  )

extern

Convert an object name to a rt_db_internal pointer

Looks up the named object in the directory of the specified model, obtaining a directory pointer. Then gets that object from the database and constructs its internal representation. Returns ID_NULL on error, otherwise returns the type of the object.
