Why WebGL

Some images of 3D L-systems are actually 3D scenes rendered by your browser and they can be rotated, zoomed or panned. You may ask: "Why do I need WebGL to view 3D L-systems?". The answer is simple: It looks much better and the operations are is significantly faster!

If you do not have browser capable drawing with WebGL 3D scenes are drawn with simplified renderer which fakes 3D. You can check whether your browser support WebGL at http://get.webgl.org/. Just look at following comparison.
