Wind-up and follow-through are explored as a part of creating a throwing motion. Everybody knows how to throw something. So we will notice the wind-up, the throw, and the follow-through dynamics of throwing.
Doing this with stop motion animation, including the math to show the pacing, you will start to look for opportunities to wind-up and follow-through in all your animation experiments.
Why Is This Important?
An animator can make almost any motion more interesting by adding some kind of wind-up and follow-through.
Sometimes the audience enjoys anticipating the action more that watching the action.
The tension of watching a wind-up before an action cues the audience that something is about to happen, and we make them wait just a split second by winding-up.
The follow-through gives our audience as sense of relief, release, and after-ness, which adds to believability of the illusion.
