Appendix A — The geometry in SWF

This appendix describes different aspects of the geometry in Flash. Note that some of the description uses 3D matrices. It is rather easy to simplify them and use just and only 2D matrices. The simplifications can usually be such that only 2 or 3 operations are required to get the proper coordinates used to render objects.

Remember that Flash uses TWIPs and thus you certainly will want to use floating points to make it easy on you.
