Some people think the engine is ready for Flash player 10, if it works after you replace its rendering code with drawTriangles() call. In this sense Sandy is certainly ready for FP10, as seen in this little demo below:
You can see Sandy’s good old FP9-compatible BitmapMaterial on the left plane along with its hacked FP10 version on the right one. There wasn’t much effort involved in this, check out source for yourself.
So ok, you can immediately create content targeting FP10 with Sandy. But does it make it truly ready for FP10? I don’t think so, there is just so much more code asking for attention than texture mapping alone…
