12:24:49Colleen<shinmera> if I have two vectors that are parallel, (but not necessarily pointing in the same direction) how do I get an *arbitrary vector* that is perpendicular?
12:25:23Colleen<shinmera> I know the cross product is just gonna be zeros
12:27:13Colleen<shinmera> can I just do (-y, x, 0) like a 2D rotation or something?
12:33:49hayleyRotating another way after yields (-y, -z, x) but that could be fooled too. Any way to generate a few rotations, such that at least one isn't a no-op?
12:34:10Colleen<shinmera> I'm just gonna use the copysign approach I linked
