rotasjonsvektoren
A rotasjonsvektor, also known as an axis-angle representation or rotation vector, is a mathematical concept used to describe a rotation in three-dimensional space. It combines two pieces of information: the axis around which the rotation occurs and the angle of that rotation. The direction of the vector represents the axis of rotation, and the magnitude of the vector represents the angle of rotation in radians.
The rotasjonsvektor provides a compact way to represent rotations compared to other methods like Euler angles
One advantage of the rotasjonsvektor is that it is continuous, meaning that small changes in the rotation
