@xphreakyphilx There's a few ways of doing it. There are measurement errors associated with all of them, but here's the easiest to understand: Take a bunch of thin sheets. Each one is a solution set for a single range. Stack the thin sheets together and then putty and sand for smoothness, and you've got the 3D cam master. Take a mold of it, then you can cast as many 3D cams as you like.
This is very, very cool. That gear assembly blew my mind! Now, at 6:42, when the narrator reiterates that either the spider shaft, or one of the end gears, might be used as the output (with the remaining two components used as input), it's a matter of algebraic truth (2 + 2 = 4, just as 4 - 2 = 2). But, in practice, were these mechanisms set up so that all three components could be physically driven? Or did the component chosen as output depend upon the application?
@RangerGordon In some cases the component chosen as output depended on the application. In many cases which part was the output component could change. That is to say the various parts could "talk back" to the others, changing the equation layout. For example. 2 + 2 = 4. This could also be expressed as 4 = 2 + 2.
@RangerGordon Sorry, accidently pressed post. So you'll always have you're numerator, denominator, and convergent. Putting them linerally is simply to appease human astetics. Where the three parts are in the equation is irrelevant. The beauty of a computer like this is it can always balance the three, and it can continually do it on the fly.

how did they manufacture the 3d cam to be mathimaticaly correct?
