note: can't figure out how to get textures to load yet. will post an update if and when i get it to work. To figure it out on your own take a look at http://x3dom.org/docs/dev/tutorial/blender_export.html
also check out http://www.sketchfab.com and http://www.p3d.in for no hassle online model hosting.
heres the example using sketchfab's easy to use service(no coding involved): http://chaitanyak.com/home.html
