Good summary Izak, thanks. Do you have any pictures yet? I suggest starting by putting a simple sphere equation into the shot() routine, but still using the libbn root solver (just like torus) to evaluate it. If you get that working, then getting the heart to work may be as simple as increasing some hard-coded libbn limits and feeding the more complex heart equation. Probably not, but it's certainly worth trying first and will take just a few minutes to test. Cheers! Sean p.s. Please don't include the entire digest on replies.
