Understanding Easing (Explaining Penner’s equations) – JavaScript and ActionScript. Despite the commonality of the classic easing equations, largely attributed to Penner, there doesn’t seem to be the in-depth examination of “how it works” that a lot of code is subject to nowadays.
First, a quick clarification on the most popular easing Classes. The “standard” easing classes (that provide predictable inertia), are Linear, Quad, Cubic, Quart, (Quintic or Strong) There are almost all identical. The only difference between them is the number of times the change is multiplied by itself. Math - easing functions for bell curves?
