Events
pointCloudsChanged
Invoked once per frame with information about the ARTrackedObjects that have changed, that is, 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.
Declaration
public event Action<ARPointCloudChangedEventArgs> pointCloudsChangedEvent Type
