1. Introduction

Animation is the art of creating the optical illusion of moving pictures.

When a set of related images are shown rapidly one after another, people sense them as one continuous motion picture.

This is the principle behind all motion images such as video, graphics and film. The effect is called 'persistence of vision'. It is lucky we have it, as it means we can enjoy looking at films.

This mini-web will introduce you to the subject of animation.
