12.Animation Gimbal Lock

In computer animation gimbal lock is the loss of one degree of rotation in a joint. In computer animation this means that there has been a significant amount of rotation that has passed the 180 degree mark, and the computer doesn’t understand which direction you want to rotate. This will look like a very fast rotation hiccup when your animation is played back. To avoid gimbal lock make sure you choose a rotation order that would be suitable for your animation. The rotation order allows you to reevaluate how each axis reacts as an object is rotated. Certain applications also include tools that reinterpret rotation values that cause gimbal lock in order to help iron out discontinuities in animated-rotation data sets.
