I have 2 3D vectors lying on a 3D plane, and I want to find the angle between them.
How can I find both the angles measured clockwise and counterclockwise (a positive and negative angle)?
I've tried using atan2d(norm(cross(v1,v2)), dot(v1,v2)), as to my understanding returns a negative angle if the angle is greater than 180 deg. However, it still only returns the smallest positive angle that is smaller than 180 deg. Changing the order of v1 and v2 doesn't make a difference either.
Thanks for all replies! I greatly appreciate it.
