Introduction
So you want to learn 3D in Flash eh? This is the place to start. It's an intermediate level tutorial discussing the core concepts involved in what's needed to create 3D in Flash. Though it takes a very primitive approach to handling the 3D described, the tutorial does assume a fairly moderate level of experience in using Flash and ActionScript.

Here is an outline of all the sections covered. This is not necessarily an easy topic so you should really start from the beginning. Enjoy.
