Real time ambient occlusion on ActionScript3

wonderfl | Real time ambient occlusion

Move mouse to move camera and click to stop motion, Press z key to switch no/off ambient occlusion.

Low quality and low performance global illumination claculation on flash10.
I just create this as a "Proof of concept" for the gouraud shading based ambient occlusion. As the result, I think that its not a good method to calculate G.I. in dynamic (object moving) scene, but it possible to calculate approx. G.I. of static scene in a short time.
