BTW, WRT projects using a lookup table... https://hg.hedgewars.org/hedgewars/file/tip/hedgewars/uSinTable.pas https://hg.hedgewars.org/hedgewars/file/tip/hedgewars/uSinTa... 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 Maybe a little out of date, but this is old code.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.
