Graveyard Keeper: How the graphics effects are made

Indeed. And you don't even need square roots for identifying the three closest, since squared distances are just as good for that. So it's, what, a few instances of very basic arithmetic and then three roots? I don't see the complication either. It would be nice to know which part of their process introduced the difficulty. Was it the update frequency?

I might even avoid the squares and use a manhattan distance metric instead. No multiplication at all, just absolute value and addition.

finding an approximate root for these purposes can be really quite fast, as was demonstrated in Quake III. https://en.wikipedia.org/wiki/Fast_inverse_square_root
