A term I've often heard is "gimbal lock"[1]. Can happen, eg, when a player points the camera straight up, then tries to rotate themselves (depending on how your axes are set up). I don't believe quaternions _ever_ have that particular problem, so not quite sure what is meant by "less often," here.

- mrcode007 3y agoYou’re right, quaternions don’t go singular. I misremembered what the problem was. And the problem with the quaternions is that the multiple revolutions will resolve to the same quaternion and then you don’t know how many times you’ve revolved around. For some applications this is important to know.
