| | To visualize quaternions in the fanciest way, visit Ben eater, Quaternion. Euler angles suffer from a problem of gimbal lock. When rotating around a 3-perpendicular axis in euclidean space, if either two of these axes align i.e becomes parallel, it causes gimbal lock. Once the object is locked, the object will lose one degree of freedom for rotation. This video provides an intuitive explanation of the problem. Pitfalls When converting the Euler angle to a quaternion, it will lose some information.

| First things first: what am I talking about? I'm talking about something that finds great use for deferred rendering: reconstructing the 3D position of a previously-rendered pixel (either in view-space or world-space) from a single depth value
