I've been tinkerin with the new flex 2.0 Beta and what started as an effort to test ActionScript 3.0 math performance turned into something considerably more. Having always had a facsination with 3D math, I decided to write a simple 3D engine in flex 2 thinking it might be useful someday. While the usefulness remains to be seen, I had a lot of fun building this thing. Here are some of the highlighted features:

• XML model definition
• Ploygon surface styles (fill color, line color, alphas)
• Symmetry math to mirror a model (see the face demo)
• Vertex tweening so you can control a vertex’s movement
• Animation Sequences to combine multiple vertex tweening groups (see the talking and/or kiss animations in the face demo)

!!!DEMOS!!! Note: These flex demos require Flash Player 9 or higher.

I've been trialing the flex 2 alpha with player 8.5 and have been most interested in the strict typing and the implications it has in compiler optimization and application performance. So I put together a little demo app to experiment with some math calculations. You can see some apps here and here . Please note that you will need flash player 8.5 to see the demo. Here is a screen snapshot:

This little guy was also showcased on the macromedia labs web site here.

I look forward to throwing some more examples up on my blog in the near future and maybe even getting a another spotlight on the labs site :)
