Papervision 3D and AS3.0

I’ve just started to learn papervision3D and till now I have some question on the coding it used. Isit a stand-alone coding special for papervision? or isit the same code with AS3.0?

From what I’ve know till now, to use the papervision3d is like depends on how you apply the classes that have already been made(unless you could write your own classes). And it seems like using papervision classes the structure wise have to be very organized, if not there would be many errors popping out. And seems like there’s not many tutorials compare to AS3.0 maybe due to its still very new, or more difficult to learn compare to AS3.0?
