The third step to craft a compelling message using 3D graphics and animation is to apply the principles of animation, such as timing, spacing, easing, squash and stretch, anticipation, follow through, overlap, arcs, secondary action, staging, exaggeration, and appeal. These principles help you to create a motion that is realistic, expressive, and dynamic. For example, you can use timing to control the speed and duration of your animation, spacing to control the distance and direction of your animation, easing to create smooth transitions between poses, squash and stretch to create elasticity and weight in your animation, anticipation to prepare the viewer for the next action, follow through to create continuity and realism in your animation, overlap to create fluidity and complexity in your animation, arcs to create natural and graceful curves in your animation, secondary action to add detail and interest to your animation, staging to direct the attention and focus of the viewer, exaggeration to enhance the emotion and impact of your animation, and appeal to create charm and personality in your animation.
