Easing is a method of distorting time to control apparent motion in animation. It is most commonly used for slow-in, slow-out. By easing time, animated transitions are smoother and exhibit more plausible motion. The easing types in this module implement the ease method, which takes a normalized time t and returns the corresponding “eased” time tʹ. Both the normalized time and the eased time are typically in the range [0,1], where 0 represents the start of the animation and 1 represents the end; some easing types, such as elastic, may return eased times slightly outside this range. A good easing type should return 0 if t = 0 and 1 if t = 1. See the easing explorer for a visual demonstration. These easing types are largely based on work by Robert Penner.
