Thanks for the feedback. Sorry about that, but it inherits from the fact that none of Three.js' demos resize. This is because doing it is a lot more fun than it looks: not the entire DOM canvas has to be changed, but all the rendering engine behind has to be recreated (camera, scene and so on). I'll see if I can make it work.

IIRC, you can change a Renderer size using renderer.setSize(w, h). In order to update the camera aspect, you just have to use : camera.ratio = w / h; camera.updateProjectionMatrix().
