arch 481: 3d Modeling and Rendering

In principle, an animation consists of a series of completely separate image frames, each of which is displayed in sequence to create the illusion of motion. In practice, large sections of one frame may be unchanged from the previous frame, and human eyes don't detect small discrepancies between frames that aren't visible for long. This creates an opportunity to save space in the animation file through various "compression" strategies. This series of small movies lets you see the visual and filesize implications of various compression algorithms.
