Impetus.js

Impetus is meant to be used as a part of other components — these simple demos just demonstrate the momentum. For an example of a practical implementation, take a look at Spherical.js.

Usage

new Impetus({
    source: myNode,
    update: function(x, y) {
        // whatever you want to do with the values
    }
});
