# Angular Velocity

Hi,

I have a question about angular velocity (in 3d). I get passed a rotation axis (vector) and the angle of rotation in radians from another software (let´s say from a scripted rigid body rotation). However, the rotation axis is normalised. How can I put these two together so the vector fully represents the angular velocity (as my understanding is that the length of the vector represents the angle of rotation normally)? Can I set the length of the rotation axis equal to 2pi/rotationangle? Or to put it differently, is the rotation axis vector of length 1.0 if the object rotated 360 degrees? Or is it of length 2pi?

The length of the vector should be the angular speed in radians per second. So just multiply the two things you are being passed together.

thanks!
