[Papervision3D] [NEW REVISION] Papervision3D AS3 RC1 (Revision 77)

[Carlos Ulloa]

Hi,

The render loop code remains identical, so no performance is lost there. On
the other side, there are huge speed improvements, particularly when using
smooth=true. The changes don't have any effect when running in previous
player other than slightly higher ram usage.

In terms of image quality, take a look at this:

The difference is bigger on textures that are rendered in a much smaller
than the original, but it looks great on bigger textures too.

It's VERY cool,
