Singularity AS 3 Rigging Classes
The AS 3 rigging classes are used for skelton rigging and skinning of 2D characters. The rigging class library is organized around the development of highly specific articulated rigs. The current focus is on humaniod bipedal characters. In a 3D animation package or game engine, a bone hierarchy would normally be represented as a tree structure. In this class library, bones and chains are organized in a structure that is easier to deconstruct and understand by OOP programmers. This structure has some performance advantages, particularly when propagating FK in a 2D rig.
