This example is shows how to setup multi-monitor displays like <a href="http://code.google.com/p/liquid-galaxy/">Google's Liquid Galaxy using three.js</a>.
|
||
|
|
Here 5 monitors are simulated using 3d css. WebGL is then rendered onto each one.<br/>
|
||
|
|
Note: 3d css support required! Use Chrome, Safari or Firefox 10
