16.4 PATH PLANNING

---

When we have simple features, paths are easy to generate. These features include,

- steps

- pockets

- holes

- etc.

Typically paths for these will repeat as shown below,

For complex surfaces we want to contour appropriately. These surfaces will almost always be represented with spline patches.

Recall that a spline patch can be represented parametrically

A simple algorithm to cut the surface is shown below.
