An example of secondary motion would be the motion of clothing over the surface of a moving figure. In general, secondary motion is caused by the motion of a primary object. In Balloon Guy, the motions of the string, the dog's ears and persons head, are all secondary motions caused by the general motion of the characters themselves. Exaggeration Exaggeration involves making the motion more dramatic than one would observe in the real world. If a scene is animated with little or no exaggeration, the motion will be dull and listless.
Animators use exaggeration to sell the action or the movement of a character.
The exact amount of exaggeration that is required is difficult to judge, but an interesting observation can be made. The version of the animation always looks more exaggerated than the final rendered frame. Exaggeration of motion is not always the way to go, but often exaggeration of motion characteristics is needed to create interesting motion. Exaggeration does not have to impart a cartoon feel to be effective. After the motion has been blocked out, it's up to the animator to decide which movements must be exaggerated in order to enhance the animation.
