Find angle between two vectors python

WebIf your two angles are x and y, then one of the angles between them is abs (x - y). The other angle is (2 * PI) - abs (x - y). So the value of the smallest of the 2 angles is: min ( (2 * PI) - abs (x - y), abs (x - y)) This gives you the absolute value of the angle, and it assumes the inputs are normalized (ie: within the range [0, 2π) ). WebJan 31, 2014 · The (directed) angle from vector1 to vector2 can be computed as angle = atan2 (vector2.y, vector2.x) - atan2 (vector1.y, vector1.x); and you may want to normalize it to the range [0, 2 π): if (angle < 0) { angle += 2 * M_PI; } or to the range (-π, π]: if (angle > M_PI) { angle -= 2 * M_PI; } else if (angle <= -M_PI) { angle += 2 * M_PI; } Share
