A two-dimensional drawing api meant for modern browsers. It is renderer agnostic enabling the same api to render in multiple contexts: webgl, canvas2d, and svg.

Download the minified library and include it in your html. Alternatively see how to build the library yourself.
<script src="js/two.min.js"></script>Here is boilerplate html in order to draw a spinning rectangle in two.js:
<!doctype html>
<html>
<head>
<script src="js/two.min.js"></script>
</head>
<body>
<script>
var two = new Two({
fullscreen: true,
autostart: true
}).appendTo(document.body);
var rect = two.makeRectangle(two.width / 2, two.height / 2, 50 ,50);
two.bind('update', function() {
rect.rotation += 0.001;
});
</script>
</body>
</html>Two.js uses nodejs in order to build source files. You'll first want to install that. Next you'll want to install node-minify:
cd two.js/utils
npm install node-minify
Then open up ./utils/build.js in the text editor of your choice. You'll see an array at the top called files. This is the list and order of source files that get compiled to the built source. Feel free to add, subtract, or modify based on your needs.
If you're making an application and you're only using one renderer (i.e: svg context) then it is highly recommended to remove canvas and webgl renderers from your build in order to drastically decrease your file size.
Finally, build the project:
node two.js/utils/build
Nightly
- Ensure sure that
manualproperly is set on construction ofTwo.Polygonthat it bindsTwo.Anchor.controlschange events - Added automatic High DPI support for
webglrenderer - Updated
two.interpret(svg)to handle compound paths - Added
Two.Anchorwhich represents all anchor points drawn in two.js - Modified source to not have any instances of
windowfor node use - Updated to underscore.js 1.5.1
- Added
Two.Utils.getReflectionmethod to properly get reflection's in svg interpretation - Made
Two.Vectorinherently not broadcast events and now needs to be explicity bound to in order to broadcast events, which two.js does internally for you. - Created
