Freesteel

Const Scallop

I’m still at the preliminary stages of writing a const stepover/scallop routine. I’m making the classical version first, before the fancy freesteel version which will be smooth, spirally and have no corners.

First function needed is a really fast measure of the distance between point and contour. I’m on my second attempt now as I work out more about this subdividing weave structure. It looks like it is not wise to be inserting new points into the weave that you are measuring your distance from. It may be better to always build up the offset in a second weave. This looks wasteful, but is probably the only thing you can do if you don’t want all your pointers moving around.

A new complete waste of time: Playing on eBay. Just trying to restock some diving equipment since our garage got burgled last month. Someone at the pub explained to me how to play the system properly, and I’ve been following his advice. (The trick is, you put a big bid in 15 seconds before the end so no one else has time to bid against you and drive up your price. It’s the person in second place who sets the value.)
