Looks good Yves. Real nice soft shadows. :) Still though, one of the big key things about true global illumination/radiosity, is that objects will also infuse other objects with their own color. So, there would be a good chance that the gold color in the handle would show up at least a little on the ground. Like if you place a bright red ball on a piece of white paper; The shadow will have a reddish tint to it. What do you mean about the picture on the dome for the atmosphere?
