WebJan 31, 2014 · @andand no, atan2 can be used for 3D vectors : double angle = atan2 (norm (cross_product), dot_product); and it's even more precise then acos version. – mrgloom Feb 16, 2016 at 16:34 1 This doesn't take into account angles greater than 180; I'm looking for something that can return a result 0 - 360, not limited to 0 - 180. – imekon WebFeb 25, 2010 · The 3-D cross product of two vectors in the x/y plane is always along the z axis, so there's no point in providing two additional numbers known to be zero. Another way to look at it: the closest 2-D equivalent to a 3-D cross product is an operation (the one above) that returns a scalar. – comingstorm Feb 26, 2010 at 5:47
