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.
