<p>Using a modified version of <a href="http://github.com/alteredq/three.js">Three.js</a> by mrdoob.
|
|
|
|
<br/>
|
|
<p>Best viewed in Chrome 7/8 or Firefox 4 using WebGL renderer.
|
|
<p>Canvas renderer is very slow on anything other than Chrome.
|
|
<p>Blinn-Phong shader only works in WebGL, canvas has only diffuse materials.
|
|
<p>In Firefox 4 something is broken.
