23TIPREVERSALSWell hello there!Last month was all about muting your character. Remember that? If you don't know this principle or that principle, then you aren'tready to animate acting tests yet? Well, you might remember that one of those principles was called "reversals."Reversals aren't terribly complicated, but I know a lot of people haven't heard of them before if they aren't in a good animationschool, so let's dive in!What the heck is a reversal?! When you first hear that word, you probably think of someone changing their mind. They wantedpizza, but now they want fried chicken (and come on, who wouldn't?!) - they've reversed their opinion. They've flip-flopped, right?Well, in animation, a reversal is essentially the same exact thing.A reversal generally refers to an arc or line of action through the body mirroring into it's "opposite" shape. More specifically, areversal is usually associated with the curve of the spine mirroring in shape.Get it? Ok, cool - see you guys next month!Just kidding. That probably didn't make sense at all, huh? Ok, let's go through a more practical example. The most common wouldbe the good ol' box lift. It's hard to find a better animation assignment than the classic, tried-and-true box lift. A box lift tests yourskills in a wide variety of animation principles, and reversals are definitely one to look for in any box-lift assignment.Buckle up, by the way, because I'm about to hit you with one of my shockingly primitive drawings. While I'd love to pretend that thisdrawing is so unimpressive merely because I'm feeling too lazy to re-draw this first thumbnail of my ideas, the truth is that itwouldn't really get much better even if I re-drew it, so you might as well just stick with this one...77Copyright 2008 by <strong>Animation</strong><strong>Mentor</strong>.com.

Ok, so what's going on in this picture? Well, the crappily drawn stick-man is about to pick up a crappily drawn box. Are you withme so far?So, here's the deal. Knowing the idea of reversals HELPS the animator know the mechanics of the body. Check this out - this getspretty cool:We know certain things about how this crappily drawn dude needs to pick up his box, because of the principles of force, weight,balance, line of action, etc - all of these things that you are studying dictate the way this guy's body HAS to move, crappily drawnor not!If this box is heavy, certain things MUST happen in this guy's body in order for him to pick up the box. For one thing, he needs to gethis butt and at least one foot as close as possible to the box, right?Otherwise, he's going to fall forward, because the sudden introduction of the weight of the box will have to be held up by his feet,and compensated balance-wise by where he places his butt.Another thing we know is that he is going to anticipate the lift a little bit by lowering his bum just before he lifts. We also know thathis butt will probably lead the action, moving upwards until at least one of his arms straightens out. We also know that once thathappens, if the box is really heavy, he will have to heave with his shoulders, keeping his arms mostly straight (usually).The final thing I want to mention, is that we know that as he heaves that box upwards, he is going to fall over if he doesn't quicklyscoot his butt forward to be beneath the box, so that the weight of his body and the weight of the box line up above his feet asmuch as possible.Well, guess what happens when his shoulders go up/back, and his butt comes forward?A REVERSAL!Ta daa! See how it all comes together?Check out the pose marked #1. It's sort of a ) shape. Well, that's the best way I can show it on my keyboard anyway. But whenthose shoulders heave, and his butt comes forward to save him from falling over backwards, his spine REVERSES into a ( shape, asyou can see in pose #2.For me, this is the sort of thing that makes animation so interesting. You've got this giant (endless!) pile of skills and principles tolearn, and they all really do come together magically when you're creating an action like this. All of those things we just talked aboutcan really be described by ONE animation concept - the reversal.78Copyright 2008 by <strong>Animation</strong><strong>Mentor</strong>.com. All rights reserved.
