Inspired by this question that attempts to reverse engineer a pseudo code chunk, I'm wondering how to use the Rodrigues' rotation formula to calcuate an Euler angleset for one point to face another (between 2 points).
I've seen some implementations of the formula, such as this C++ implementation which calculates a rotation matrix. Is there an implementation that calculates Euler angles? or would I have to calculate a rotation matrix and convert that into Euler?
