 These controls are fairly self-explanatory -- adjusting the controls changes the perspective of the live camera view.  The ''Shear'' controls are used less often, which is why they aren't normally displayed.
-Back to the "ball falling from a building" example, or in our case, ball falling from a parking garage: Vizy is pointed up at an angle to capture the motion of the ball as it falls.  Vizy is tilted 90 degrees to capture more of the vertical motion.

-Before we adjust the perspective the ''x velocity'' graph is curved, but after the perspective is corrected, the ''y velocity'' graph becomes a straight line, which is what you'd expect from an object experiencing constant acceleration.  (Not to confuse things, but the ''x velocity'' graph essentially becomes the ''y velocity'' graph after we rotate (roll) the perspective 90 degrees, hoo boy...)
