Hi,
papervision is - like you say "quite good for small 3d elements".
My experiences are that it's a plugin/engine full of possibilities and gadgetry.
For "bigger" projects (like small games) it's currently too half-baked in speed and render accuracy.
On the other hand there are some nice demos on the
flexblog...
Maybe v2 will be better and stable enough for small business projects.
I've send a colleague to a training these days (
http://entwickler.de/zonen/portale/psecom,id,99,news,39346,p,0.htm) to learn more about the engine...
If you're interested I'll post some of the "news" about papervision next week...
