Principles of animating a Bouncing Ball - 4

In-betweens

The last step is to do the in-betweens. In-betweens are the drawings/frames between the key frames which help to create the illusion of motion.

When doing the in-betweens using traditional animation you need to remember to transform the ball from its round shape to move of an oval shape but using 3D such as Maya it will do the in-betweens for you but you will need to use the graph editor to make sure the ease-in and ease-outs work and that the ball is stretching along the arc and that the transitions work. Your ball bounce with in-betweens should look a bit like my drawing below on the right.

The best way to work out your animation is to PLAN! You will hear this over and over again but planning is very important. It may seem at the time like you know what you want and can skip it but trust me when it comes to it you will end up animating and reanimating until you end up doing the planning any way.

Below is the ball bounce that I made in Flash to show what the final thing should be like. Sorry that its poor quality. Something that happens in the uploading to blogspot I think.
