Computer Animation and the Fourth Dimension

Man is a creature restricted to a world of three spatial dimensions in which he is reasonably free to move about at will except for the arbitrary territorial boundaries imposed by different nations. Man also lives in another dimension over which he presently has no control other than to watch its continual forward movement in the mechanical and electrical gadgets he has devised to measure this dimension which he calls time. Many people call time the fourth dimension, but because of its many unique qualities I would rather consider time as a special dimension. Therefore, in this paper the fourth dimension is a fourth purely spatial dimension not to be confused with time.
