hello! i just found a visualize drag and drop WEBGL editor ,you can try this:
http://idflood.github.com/ThreeNodes.js/public/index.html
it work the way just like VIRTOOLS, the code become a CUBE,each cube have its input port and output port.
some people say the code of webGL is much like Away3D.
what i think is will this editor also work for Away3D after a little bit reform?
