Thank you very much for the links to the archived SDK and documentation, Eric.
Again I am planning to custom program the deprecated gestures circle, swipe, key tap and screen tap. To make good use of your own extensive experience with the Leap Motion device, I would like to first have a look at the corresponding deprecated code in C++.
Defining gestures can be tricky, in particular gestures spanning over multiple frames such as the deprecated circle gesture.
Did you ever happen to make any of your code public, please, in particular the code for these 4 deprecated gestures?
Looking forward to hear back from you.
