Description
update of slide9 (Fishtank VR). To understand the difference with the mechanism described on slide 6, it's important to remember that on slide 6 the motion parallax phenomena characterize the dispalcement of real 3D objects on our retina whereas in slide 9, the displacements are those to compute on the "window" through which we see the virtual world. Make the parallel with a real world window through which you observe the landscape ; if we want to replace that real window by a screen simulating what you see through the window, slide 9 describes how to display landscape entities on that screen when you move your viewpoint relative to the screen.
