I just stumbled across an open-source 3d physics engine for Flash that is able to compute positions and rotations in 3D engines such as Papervision3D, Sandy and Away 3D. It is still in development but I am hoping to look more into it over the next little while. Write-up, source and some tutorials can be found at : http://seraf.mediabox.fr/wow-engine/as3-3d-physics-engine-wow-engine/
here is a great site for keeping up to date with papervision as well as getting some great examples and tutorials.
Great article written by John Lindquist of http://pv3d.org outlining the basics of Papervision. This is part 1 of a series of 6 articles to be written.

Well, I have been talking about it with friends and co-workers for the longest time but have never had the time to play with it. The other day I found a couple of hours to see what I could come up with. I decided to create a snowboard in 3ds max and see what I could do with it in Papervision, just going through a couple of tutorials.

I plan on improving on this as I find more time to get into both AS3 and Papervision. I am hopefully going to create a little flyout in max to automate and customize the creation of the board and then add a little bit more interactivity to the board once it is in flash.
