BTW, WRT projects using a lookup table...

I think there's even a github mirror someone made since that's where you were looking. Maybe a little out of date, but this is old code.

oh... also, sine table isn't just a performance thing. Hedgewars does fixed point custom math for deterministic lockstep, so keeps the math simple and predictable on various compilers/hardware.

That's something I'd wondered about with games that require determinism. Seems fairly challenging to deal with for that sort of game.

Thanks for taking the time to make such an incredible article. Made my day reading it this morning.

Fixed. Thanks!
