For example, if your matrix moves an object five units up, the inverse moves it five units down.

You can see this by the numbers.

For practice try orbiting fully around your model.

Of course, it doesn't make any difference.

You don't need reverse. You don't need parallel parking.

And the way this happens is through the phenomenon of persistence of vision.

What I if I did it in the other order? Would it make any difference?

As you focus on the wooden form, it rotates.

The translation moves the model to the origin, where it's now centered.

And then, if you saw, the panels actually rotate.

Use old rotation style.

Oh boy.

So it is a vector quantity and the direction of the vector is dependant on which way it's spinning.

In this position also observe patellar tracking.

And what I'm going to do is, I'm going to hold it here, and I'm going to spin it.

And you can try this when you go down to the pub, later on.

Move your eyes around, blink, maybe close one eye.

Hopefully that makes sense.

If I spin this pulley, the small one's going to spin much faster.

Raise the Z axis out of the way and recall that, in our case, we adjusted the B axis position to B0.003

And gone, too.

So what if I do B, which is a sixth of a turn, followed by C, which is a third of a turn?
