easing

dependency-free collection of easing functions

lerp(a, b, t)

interpolate between a and b as t goes from 0 to 1. Will extrapolate when t goes outside 0..1

ilerp(a, b, n)

returns a value 0..1 of where n lies between a and b. will return values outside 0..1 when n is outside a..b

clamp(a, b, n)

constrain the value n to the range a..b

scale(a, b, c, d, n)

map n's position in the range a..b to the range c..d

quadEase(a, b, c, t)

project t in the 1-dimensional quadratic bezier defined by a, b, c an optimized equivalent to lerp(lerp(a, b, t), lerp(b, c, t), t)

cubicEase(a, b, c, d, t)

project t in the 1-dimensional cubic bezier defined by a, b, c, d an optimized equivalent to lerp(lerp(lerp(a, b, t), lerp(b, c, t), t), lerp(lerp(b, c, t), lerp(c, d, t), t), t)
