TQ3Status Q3Controller_GetTrackerOrientation (
TQ3ControllerRef controllerRef, 
TQ3Quaternion *orientation);

A reference to a controller.

orientation

On exit, the current orientation of the tracker associated with the specified controller.

DESCRIPTION

The Q3Controller_GetTrackerOrientation function returns, in the orientation parameter, the current orientation of the tracker associated with the controller specified by the controllerRef parameter. If no tracker is currently associated with that controller, Q3Controller_GetTrackerOrientation returns the orientation of the system cursor's tracker. Q3Controller_GetTrackerOrientation has no effect if the controller is inactive.
