Unfortunately, while the code is mine to reuse, it is not
mine to distribute, and I can not post it in toto. But you
probably wouldn't want that ;) It's four programs, each
about a thousand lines, and the math (actually, geometry)
behind the path generation is hard to follow (involving
three cartesian systems and two polar systems, and multiple
translations between them.)
Sorry, don't mean to suggest it's not of interest or too
hard to understand, 'cause neither are probably true, but I
still couldn't post it all...and being a huge open source bigot
myself, it's not easy for me to say that.
