[Papervision3D] Papervision3D or Director ?

[Carlos Lunetta]

wow, Metropolis. You brought that app back from the dead - I haven't 
even heard about it anymore since 98...

The Havok physics extra used by Shockwave3d does a pretty good job at this, but programming Havok requires some pretty savvy 3d/physics-sim knowledge.   Few Director programmers seem to have used it.  A shame there aren't more sites like this made http://www.gorillaz.com/geep/finaldrive.htm

Virtools may have added more advanced shading techniques since then.  For basic 3d functionality, however, not much has really changed since 2001.  Virtools browser penetration is, of course, miniscule compared to Director's  http://www.adobe.com/products/player_census/shockwaveplayer/version_penetration.html  and Flash's is, of course, even better http://www.adobe.com/products/player_census/flashplayer/version_penetration.html

It appears to make things so simple in demos, but when you try to create a real application with it the visual graph metaphor it quickly becomes so convoluted that I start to yearn for a flat text editor.
