B.2. Animation

Animations take various forms. For example, you can show different pictures at a fixed time intervals in the same or different positions. While one picture is displayed, all other pictures of the same objects are made invisible. Usually, a timer is used to regulate the timing for displaying the pictures. This creates an illusion that the object is moving. You can also create animations by drawing instead of using existing pictures. For example, you can draw different colors on the same graph, again at a fixed time interval. This can create an impression that the object is blinking or the lights are moving. Also, you can create a rotating object (or an object with different motions) by drawing some part of the object at a different relative position while the object moves. This section presents three examples to illustrate how each of these effects can be achieved.
