Greetings! I am a programmer currently working at Gameloft, making games. My bachelor's degree thesis was a WebGL particle system engine written from scratch, so I am quite familiar with rendering 3D objects and scenes in javascript. I can help you finish this task in a couple of days. If you need additional proof of my past work with javascript and WebGL, i can send you my thesis via PM.
EDIT:
I've read the new project definition. I can supply an offline method as well (either a windows application using OpenGL to render the scene parts to .png files or a webpage that does the same thing, using WebGL). This will take a little more effort though, so I've updated my bid as well.
