Q3Controller_MoveTrackerOrientation

You can use the Q3Controller_MoveTrackerOrientation function to reorient a controller's tracker relative to its current orientation.

TQ3Status Q3Controller_MoveTrackerOrientation (
TQ3ControllerRef controllerRef, 
const TQ3Quaternion *delta);

controllerRef

A reference to a controller.

delta

The desired relative change in the orientation of the tracker associated with the specified controller.

DESCRIPTION

The Q3Controller_MoveTrackerOrientation function changes the orientation of the tracker currently associated with the controller specified by the controllerRef parameter by the relative amount specified in the delta parameter. If no tracker is currently associated with that controller, Q3Controller_MoveTrackerOrientation changes the orientation of the system cursor's tracker relative to its current orientation. Q3Controller_MoveTrackerOrientation has no effect if the controller is inactive.

Note

Calling Q3Controller_MoveTrackerOrientation might cause the notify function of the controller's tracker to be called.
