This was code was originally built in 2008 for my first version of bizzark.com. I isolated the 3d background code here for you to browse. It uses Mathieu Badimon's FIVe3D for the 3D API. I created custom classes to create the 3d world with randomized triangles and all the randomized motion. Making use of all that Trigonometry I learned in school!
PS. You won't be able to run it unless you download and import Mathieu Badimon's FIVe3D in your flash settings.
