Ever watch Disney’s original “Aladdin” and notice how Princess Jasmine’s long ponytail follows behind her whenever she turns her head? How about when a flag blows in the wind? Its flapping motion seems to be directly related to how the wind is blowing it, doesn’t it? But why is that?

 

Well, in this lesson, I explain exactly why there are these “primary” and “secondary” motions when things move and how they are related to each other. I will take you through the process of observing how these opposing actions work and how to apply them to your animations in a realistic way.

 

This principle of Drag and Overlap can be confusing at first, but don’t worry. I will demonstrate how to apply this concept by animating a ribbon attached to a bouncing ball, a sheet blowing in the wind, and a girl’s hair as she turns her head. Follow along with me and see how it works!

 

Some new concepts you will learn in this lesson are:

▪ Primary and Secondary Actions

▪ How inertia and energy affect objects

▪ Opposing Actions

▪ Reversal

▪ Expansion and Contraction
