Here's a simple tech demo showing a 3D music visualizer using the flash player 10's new 3D APIs, with a rotating sphere that transitions into a disc using GTween. Nothing too complex, but the result is kind of neat, and it is simple enough to serve as a quick entry into using the new APIs if you're getting started. It also uses the new Vector type in player 10.

To me its cool that you can now whip out simple 3D content right in Flash in a matter of minutes, and then step up to the big guns with PaperVision 3D or Away 3D as necessary.

I'll be sharing some of the other simple 3D experiments I've been working on over the coming weeks.

Flash Player 10 is required to see this experiment.

You can download the source code here. Just throw any MP3 into the folder with the SWF, and call it "music.mp3". It's set up for Flash CS4, but there is no code or assets in the FLA, so you should be able to compile it as an ActionScript project in Flex.
