Several zoom screens may be required to pinpoint a specific area or items. Basically there are two types of animation. The first type of animation that can be used is called travelling animation. Travelling animation is where an object moves from one part of the screen to another. The second type of animation is called repetitive animation.
Repetitive animation is used to give motion to stationary objects.
Repetitive animation is developed using a sequence of mini-frames that repeat in sequence to give the illusion of motion. Below is an example of four mini-frames which, when viewed, will appear to be a wheel being turned by a motor. When designing repetitive animation sequences, use the form entitled Repetitive Animation Form found in the Forms section of this Guide. A widely used form of the repetitive animation is the GIF animation used on the Internet. For more information about the construction and use of GIF animation consult the following sites on the Internet.
