ABSTRACT
The best way to understand animation is to look at the art form in which it has primarily been used: motion pictures. In this case, the illusion of motion is created by drawing or otherwise recording a series of images on film and then projecting them at 24 or 30 frames per second (for film and video, respectively). The illusion is maintained by a property of the eye-brain combination known as persistence of motion: the eye-brain system sees two frames and invisibly (to our perception) fills in the gaps between them, thus giving us the notion of smooth motion.
