Yes, I would be very interested in your report on gimbal lock.

That is precisely the point, my approach is by no way meant to be general. It simply relies on the assumption that we have an animation with yaw, pitch, roll rotations of at most a few degrees per time step. So the 3 rotation axes remain pretty much orthogonal and we remain far from any singularity.

Again, that is not meant to be general but to me the assumption seems reasonable within the framework of an animation.
