A thing to calculate the circumcircle and circumcenter of a triangle. You can drag the points around :P
hmm I wonder what this is going to be used for... (cough cough another image processing thing) (Line intersection code from @rubiks_cube_guy238, everything else by me :P) There's some weird lookin' offsets of the circle when the points are too close to being on the same plane, this is just because when I render the circumcircle, I go to the circumcenter, change direction and okay actually I'm not going to explain it. Basically it's because of Scratch's fencing limits where you can't go far offscreen - it's fixed at this link: https://turbowarp.org/910855061?offscreen
