Squash and Stretch

This is a useful way in animation to give the illusion of volume and weight when a character or an object goes through an action, such as facial expressions, exaggerated movements or a ball bouncing. Depending on the reaction that the animator desires the squash and stretch can vary, either very realistically or very over the top. For example in Fig.1 we can see the squashed and stretched forms of basic shapes, and in Fig.2 the forms of some objects. Also the video shows some more examples of squash and stretch.
