Polygonal Labs - Data structure
Interesting classes for structuring data. At the first look, it’s seems quite advanced for an ordinary flash developer. But just have a look and get back there when you need to make a fast pathfinder, item-queue/stack or node-tree. And significent faster and simplier when working with data relations. (Is used with the 3D physics engine mentioned in the previous post)

First physics engine in 3D
This engine is based upon APE and uses Sandy 3D. But it handles abstract objects, so you can link it to PV3d as well . By combining different view in 3d-scene the position and rotation is simulated. http://seraf.mediabox.fr/wow-engine/as3-3d-physics-engine-wow-engine/
