I come back every couple of months when I have a new project involving sdfs. And almost every time it's a bit of trial and error figuring out the parameters. It's workable, but a minor pet peeve that they're not described or named better.

It's a priceless resource nevertheless.

I was just about to say the same thing. This is bad code/documentation. Single letter variable names is almost always wrong if it isn't i for an index or such (and even then, would typing 'idx' kill you?). And as parameters, so much worse. Don't make me guess how to call your function please.

or maybe terseness helps put your brain into pure algorithmic mode? After all that's how mathematical notation works and SDFs are pretty mathematical.
