# Transition
Transition is a simple animation library.
It is based on requestAnimationFrame.
Its only job is to calculate a delta based on a duration and an equation.
It is kept simple to be able to animate any number of things, with any interpolation logic.
## Properties
An animation can be `idle`, `active`, or `paused`.
- `active` means the animation is started. The animation can be either paused or stopped.
- `paused` means the animation is in a paused state. The animation can be resumed.
- `idle` means the animation is neither paused or active. It can be started.
## Usage
```js
var Transition = require('transition');
var equations = require('transition/equations');
var animation = new Transition(1000, equations.sineIn, function(delta) {
console.log(delta);
});
// an animation should be started
animation.start();
// is the animation running?
console.log(animation.active); // true
// an animation can be paused and resumed.
animation.pause();
animation.resume();
// an animation can be stopped
animation.stop();
// you can also check if it's idle.
console.log(animation.idle);
```
## Example with Transform3d
```js
var Transform3d = require('transform3d');
var Transition = require('transition');
var equations = require('transition/equations');
var transform1 = new Transform3d();
var transform2 = new Transform3d();
transform1.rotateX(0).rotateY(0).scale(0.9);
transform2.rotateX(360).rotateY(180).scale(1.5);
var interpolation = transform1.interpolation(transform2);
var animation = new Transition(1000, equations.cubic, function(delta) {
element.style.WebkitTransform = interpolation.step(delta).compose();
});
animation.start();
```
