Q: Axis angle interpolation lerp vs slerp
Edited by Abhaya Uprety on Reason: Initial post
Linearly interpolating between 2 orientations represented by axis angle results in non-constant angular velocity. Spherical interpolation however doesn't suffer from this problem.

Why is that? Hopefully someone could point me to mathematical derivation. Thus far I am able to derive axis angle to matrix representation and back, but haven't found explanation for this.
