Touching 3d object - dominoes example

September 20, 2012 - 3:09am #1

Hi

I am reading the dominoes example but I don't figure out where and how the app detecte and track the finger that tuoch the domino !
It's not a normal touch , the finger touch the 3d object not the screen , how it works ?! 

I see touchesBegan , touchesCancelled , touchesEnded , touchesMoved in EAGLView  that call  dominoesTouchEvent in dominoes

and see the projection of the touch

 but I can't figure out the first event that detects the finger :(  

if there is is any documentation about this example please give me it !
