Ease

public struct Ease

A type of easing function, described from an algorithmic classification and acceleration pattern, providing the sense of motion.

“Nothing in nature moves linearly from one point to another. In reality, things tend to accelerate or decelerate as they move. Our brains are wired to expect this kind of motion, so when animating you should use this to your advantage. Natural motion makes your users feel more comfortable with your apps, which in turn leads to a better overall experience.” - Paul Lewis
