Events

trackedObjectsChanged

Invoked once per frame with information about the ARTrackedObjects that have changed, i.e., been added, updated, or removed. This happens just before ARTrackedObjects are destroyed, so you can set ARTrackedObject.destroyOnRemoval to false from this event to suppress this behavior.
