Thing is, I can download and use PV3D (and have been playing with it) and were I doing something for work, that's what I'd do. With my own personal screwing around, I'm more concerned that the math I'm using is correct not making things easy on myself. As an aside, I have the AS2 version of that book from years ago. Didn't know if 3 was worth grabbing as well, so thanks for the rec. Jer
