seems like a new hot topic.... http://blogs.unity3d.com/2011/02/27/unity-flash-3d-on-the-web/#comments
These are exciting times. Today, at the Flash Gaming Summit in San Francisco (of which we’re proud Gold Sponsors), Adobe has announced the public availability of a beta version of the Flash Player, codenamed Molehill, that has a very interesting new feature: hardware accelerated 3D support.
Molehill exposes a very low-level shader-based interface to the graphics hardware. Adobe has decided to focus on that low-level part, and do that really well. The molehill pre-release will not be shipping with a 3D engine, scene building tools, model and animation importers / exporters, physics, lighting or lightmap creation tools, etc.
Hmmm….does that list sound familiar? It sounds a lot like what you all love Unity for!
In the past few months, our engineers have been investigating the possibility of adding a Flash Player exporting option to Unity. That investigation has gone very well, and we’re moving into full production.
