- The touch event is handled by TouchController.java.
- This implementation of TouchController detects 3 finger gestures:
- slide: it detects where 1 finger touches down the screen and where it moves. So you have a line. With this line you have a 3d vector. So you can move 3d model.
- pinch: it detects where 2 fingers touches down the screen and where they move. So you have 2 points getting closer to each other or moving away from each other. So you have a zoom in or zoom out.
- rotation: complex to explain. implementation is more complex than it should.
