npub1vgs5rx9km8njvq8e5fs7a2c2yzzmvuwfjpqwgxxlyqf6kmfeds0q7suja8 (npub1vgs…uja8) I remember that in 3D there are lots of situations where "naive" math can cause gimbal locking and like, having to detect bounds conditions that cause the thing to rotate around 359 degrees instead of just 1 degree over the bound, that sort of thing. But if you use quaternions none of that stuff happens, because they have imaginary numbers that kinda work to keep track of things in situations where a pure 3 dimensional representation would lose data. Cool, but brain hurty.
