When you see a movie at a theater, you’re actually looking at still images shown at a frame rate (images per second) that is sufficiently high to trick the eye into seeing continuous motion. Like a movie, an animation consists of the same thing: images that appear to move. Animators create each of the still images separately. In computer animation, the computer provides tools for creating the animation as well as for running it. It’s easy to create a simple animation using the GIF file format, which enables programs to store more than one image in a GIF file. The file also stores a brief script that tells the applications to pay the images in a certain sequence and to display each image for a set period of time.
