I’m trying to get a usual “virtual world” scene (such as second life’s) using (possibly free and open) as3 3D frameworks, so my first choice has been papervision3D.

Unfortunately I’m not a 3D modeler so I had to get models from the web, anyway google sketchup warehouse is a very good resource to collect DAEs (but remember they may be not parsable by ascollada).
For the human model I’ve just “stolen” a walking girl from 3Dflasho.
…and here‘s what I got combining the 2 models: a girl walking in a stadium. (girl is automatically walking forward, just use left and right arrows to make her turn)

(note: textures are about 7 mb and the whole swf is very cpu intensive) 

Take a look to the profiler, you can notice that framerate is very low even on a very good machine (i had a value range from 12 to 18 with everything loaded and 26\28 for the girl only on a macbookpro 2.4ghz and flash player 9.0.124 debug).

Next steps for me are:

1) try the same models on Away3D and maybe on Alternativa

2) search for better models (expecially for the stadium which generates too many culling issues on the ground)

3) have a mana potion

I hope to get good news from papervision and away3d mailing lists about flash 10 implementations, expecially about both engines’ drawing speed..in the while I’m going on with my tests

This the fact:
whenever you try to print something using PrintJob.send() you’ll get a blank sheet instead of the effective Sprite printout.

On previous versions of OS X and on Windows everything is working fine.

Try to test it using Language Reference’s example. It seems not to be working even on AS2 swfs.

I just submitted this bug at bugs.adobe.com, if you have access to serverside scripting AlivePDF project can be a good workaround.
If you find any workaround or want to contribute to solve this issue, here’s the link at adobe bugs: https://bugs.adobe.com/jira/browse/FP-307
