…One of the challenges that crops up again and again is…keeping material and hair and soft matter looking soft and free.…So how do we do that?…Well there is a trick and it involves using curves.…C curves and S curves, and here's what it roughly looks like when you do right.…And this could be a dog's tail or a, you know,…a piece of paper blowing in the wind or a flag.…Any number of objects can be made or built…around this basic action or variations of this action.…
So how does that happen?…I actually drew this frame by frame, just straight ahead.…You begin with a C curve.…And again, the primary motion is from wherever…it's rooted here, and we just pull it down.…And we break into an S curve around these two frames.…And then we slowly work into the opposite C.…So we go from this C into a reversal.…From this S to that S.…And this is the classic wave motion action.…It's the kind of thing you just pick up by practice, just…by, you know, being comfortable working from one shape into an opposite.…
And you can see from the domain movement actually…
These lessons are designed with Flash in mind, but work just as well with any other 2D animation program.
- Creating gesture drawings
- Comparing storyboard styles
- Squash, stretch, and volume
- Comparing timing and spacing
- Using anticipation, overshoot, settle, overlap, and follow-through
- Creating eccentric walks
- Building stock mouth shapes for dialogue
- Creating thumbnails
