Andy posted a cool example on recreating the fog effect with papervision 3d.
View Demo, and check his post with explanation.

Michael Lively posted 13 video tutorials on Papervision 3d and Flex, which will be usefull for sure to help you entering in this “new age” of Flah Platform.

Hobnox has just launched the Audiotool demo, and i can say… it’s really awesome!!! They did a great job! Now you can compose your own music, using this nice application. As Flash “Don’t make noise”, they used java for the audio signal. You can find a more complete review on this application at the Andre [...]

Another great source, that lets you create an awesome animation. ” A vertex, represented by the class Vertex3D, is basically a point in the 3D space with a ‘x’, ‘y’ and ‘z’ coordinates. The interesting part is that each of those vertices can be manipulated separately.”

This great PV3D demo demonstrates a cool 3D sound spectrum. I’ve seen some in 2D and another one in 3D, but this one is different. Eduardo used computeSpectrum(), SoundMixer.computeSpectrum(), and the PV3D 2.0.

This tutorial, is one of the most impressive particles applications i’ve seen. In this application you see an explosion and particle effects coming from a simple image in a 3D environment.
See the application demo, and read the author comments and notes.

Great article by Moxie, on the Yahoo AS3 services, demonstrating a geo spatial service enabled Flex Yahoo AS3 map application. He demonstrates how integrated geo spatial service, RIA technology, location based service and digital map can make our life easier.

Eric released the alpha version of his application.
Some of features are:

Configure galleries via XML
Configure runtime styles via XML
Associate galleries with styles
View prebuilt slideshows based on existing galleries

Den Ivanov shows us a very nice PV3D made toy with some kind of masking, that shows the same tree in the different seasons. You can Drag mouse to rotate, scroll mouse wheel for zooming & walking through portals to another season.
