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.
