This tutorial and example, is basically to start looking at the 3D world inside flash. Is possible not the best way to do it, cos it uses a lot of CPU. Anyway, you can always improve the main idea.
  
    Main features to implement is to render bitmaps textures instead of vector shapes, cos in this way you can get realistic results like papervision3d
    Another issue is the COLLADA import, to avoid model definition inside the flash code.
