TQ3Status Q3Controller_GetTrackerPosition (
TQ3ControllerRef controllerRef, 
TQ3Point3D *position);

controllerRef

A reference to a controller.

position

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

DESCRIPTION

The Q3Controller_GetTrackerPosition function returns, in the position parameter, the current position of the tracker associated with the controller specified by the controllerRef parameter. If no tracker is currently associated with that controller, Q3Controller_GetTrackerPosition returns the position of the system cursor's tracker. Q3Controller_GetTrackerPosition has no effect if the controller is inactive.
