Enumeration Type Documentation

Database target info errors.

Enumerator
VU_DATABASE_TARGET_INFO_ERROR_NONE	No error.
VU_DATABASE_TARGET_INFO_ERROR_DATABASE_LOAD_ERROR	Could not find database file or read data from it (potentially unknown or corrupted file)
VU_DATABASE_TARGET_INFO_ERROR_NO_TARGETS	Could not find any targets in the database from which an observer could be created.
VU_DATABASE_TARGET_INFO_ERROR_DATABASE_XML_REQUIRED	The database contains targets that could not be loaded directly from the database's DAT file. Image Target or VuMark databases generated prior to Vuforia 10.15 must be loaded from the database's XML file. To query the target infos from this database, and subsequently create observers, either provide the database XML file instead or regenerate the database to the latest version.

VuResult vuEngineGetDatabaseTargetInfo	(	const VuEngine *	engine,
		const char *	databasePath,
		VuDatabaseTargetInfoList *	targetInfos,
		VuDatabaseTargetInfoError *	errorCode )

Extract info on all targets from a database from which observers can be created.

Note: Note that loading the database may take a significant amount of time, it is therefore recommended that this method is not called on the main/UI thread.
