Automating Motion
Until now, expressions have helped us to orient objects automatically or to position them. In the next example, you will learn that expressions make many more things possible.
We will not only control points in this example; we will also develop a morphing algorithm whose capabilities extend beyond those of the built-in functionality of PLA or morph sequence.
This sounds more complicated than it actually is. I will be especially careful to explain the mathematics behind this process, since this method is suited for so many other tasks.
Modeling a Simple Machine
We'll begin by building a small machine, which will consist primarily of three cylinders and a cable. We'll also have a pair of ring objects so the cable can turn around. ...
