How can I access the the colour of a particular face or point? after being rendered using various light and shadow sources?

Is this possible, after a lot of searching I haven’t found any info.
Looking through the source I did see LightProbes.as, which sounds like it might be what I’m looking for, but then I couldn’t find any info on it.

no no davivd. Just capture your 3D output like here away3d com/showcase/jane_austen_regency_dressup in bitmapdata. And then use getPixelAt(x,y):uint;

I’m afraid you can’t do this except using the method that Shegl suggests. Because you can’t retrieve anything from a shader, and the only way to retrieve something from the already-rendered backbuffer is by drawing it to a BitmapData using the Context3D API for this.
