Shadow

Various debugging images with second scene

There is a clear line of shadow that seems to cut the shading on the blue sphere in the box scene. After outputing the shadow with other components, I believe that's just the artifact from Blinn-Phong Shading, where the N dot H term shifts the center of specular lighting a bit so that it happens to lie in the boundary of shadow in this case.
