eases

stable

This is a grab-bag of Robert Penner's easing equations, most of the code from glsl-easings. Pull requests for optimizations are welcome.

//require all eases
var quadIn = require('eases').quadIn
 
//require only the single function
var quadIn = require('eases/quad-in')

Usage

NPM

Each easing has its own file which can be required individually. The entry point also exports all eases with camelCase, so require('eases/expo-in-out') becomes require('eases').expoInOut.

Full list of eases:

require('eases/back-in-out')
require('eases/back-in')
require('eases/back-out')
require('eases/bounce-in-out')
require('eases/bounce-in')
require('eases/bounce-out')
require('eases/circ-in-out')
require('eases/circ-in')
require('eases/circ-out')
require('eases/cubic-in-out')
require('eases/cubic-in')
require('eases/cubic-out')
require('eases/elastic-in-out')
require('eases/elastic-in')
require('eases/elastic-out')
require('eases/expo-in-out')
require('eases/expo-in')
require('eases/expo-out')
require('eases/linear')
require('eases/quad-in-out')
require('eases/quad-in')
require('eases/quad-out')
require('eases/quart-in-out')
require('eases/quart-in')
require('eases/quart-out')
require('eases/quint-in-out')
require('eases/quint-in')
require('eases/quint-out')
require('eases/sine-in-out')
require('eases/sine-in')
require('eases/sine-out')

All easing functions only remap a time value, and all have the same signature.

v = ease(t)

Where t is typically a value between 0 and 1, and it returns a new float that has been eased.
