Q3Controller_SetTrackerOrientation

You can use the Q3Controller_SetTrackerOrientation function to set the orientation of a controller's tracker.

TQ3Status Q3Controller_SetTrackerOrientation (
TQ3ControllerRef controllerRef, 
const TQ3Quaternion *orientation);
controllerRef
A reference to a controller.
orientation
The desired orientation of the tracker associated with the specified controller.
DESCRIPTION
The Q3Controller_SetTrackerOrientation function changes the orientation of the tracker currently associated with the controller specified by the controllerRef parameter to the orientation specified in the orientation parameter. If no tracker is currently associated with that controller, Q3Controller_SetTrackerOrientation changes the orientation of the system cursor's tracker. Q3Controller_SetTrackerOrientation has no effect if the controller is inactive.

Note
Calling Q3Controller_SetTrackerOrientation might cause the notify function of the controller's tracker to be called.
