Ok, I think this is where our miscommunication is happening. When people 
speak of "reflection", they usually mean specular reflection, like a 
polished surface or a mirror. You seem to be looking for diffuse 
reflection, which is light scattered in all directions by a surface.
If you want diffuse reflection data per ray, you should modify Diffuse() 
in lighting.cpp. Maybe Diffuse_One_Light() too, I haven't looked very 
closely. If you just want the output image data, why not just use the 
output image?
