I found this page:
At the bottom of the page, it lists a pair of functions, StartExtendedTracking and StopExtendedTracking. However, when I tried to use these methods, they do not exist. The only members that the Trackable object contains are ID and Name.
Are these only available in certain versions of Vuforia? (I'm using 3.0.9) Or is the documentation simply referencing functions that don't exist?
