This library provides animation helpers for objects created with paper.js.
The API has 3 layers:

  1. Built-in effects available through animatePaper.fx: a collection of one-liners to animate objects. e.g: animatePaper.fx.fadeIn(myCircle);
  2. Property animation through animatePaper.animate() or Item.prototype.animate(): this method can be used to change the value of one or more properties of an Item based on a desired value, a duration and an easing algorithm.
  3. Hooks provide a simple way to extend the library to suit your needs. If you want to add an effect or change the behavior of an existing one, you can do so by adding properties to animatePaper.fx; if you want to add an easing algorithm, you can do so with animatePaper.extendEasing(); to change or add property hooks, use animatePaper.extendPropHooks().
