The beta release of Flash Player 10, code named Astro, is now out on Adobe labs!
After download you can check out couple of simple demos I wrote using new features:
Spherical Mapping – rotating 3D globe with alpha support. This version runs in CPU, if it seems slow …
ThreePointGradient – a colorful gradient by specified three colors and points – the colorPickers are as well dragable, try moving and changing colors ! it’s not a build-in function of graphics API, but an example of pixel bender-shader rendering a fill …
There’s not much information on the net – yet. Senocular has posted a tutorial of new features.
and here’s CJ’s demo with lightbeams !
… more info and source for ThreePointGradient.
( edit 29 Sept 2008: AE CS 4 seems to have a four color gradient !)
… check also out version of rotating globe using graphics.drawtriangles() !
Here we go

Yes, that’s a very clever comment. Ok, You must be some Don Quijote fighting people who don’t share their code. Thanks for finding my code that interesting ! – by the way, it’s not necesserly to use this. that much !
… maybe I should make this a tutorial,
like for instance in function doRotation, how the Matrix3D class has been used for counting the spatial rotations, and how that’s passed to shader’s float3×3 parameter, so that it’s all counted once in actionscript, not pixel by pixel in shader code (sin & cos, heavy operations) resulting a much better performance
And the pbj – can you open that also ?
