RemarksSoTrackerReader is a class that interfaces to trackdAPI from VRCO. It provides access functions to the coordinate data from the tracking system (position, matrix, and Euler angles). SoTrackerReader can convert the raw data from trackd with a transformation matrix (provided by the user in the application or provided during calibration). SoTrackerReader is instantiated by the SbConfig class, if the configuration file specifies the use of a tracking system (by providing shared memory keys). See SbConfig.getTrackerReader.
NOTE: trackd from VRCO (www.vrco.com) is not included with Open Inventor. If trackd exists on the system, Open Inventor will dynamically load it at run time. See trackd documentation for information about the values returned.
