The code only cares about whether or not the bounding object was hit, 
not about the distance of the hit. If, from the camera's point of view, 
the bounding shape covers the image area of the object, the object will 
be visible. It doesn't care if the bounding shape is actually in front 
or behind the object. However, from the point of view of a light source 
in the same scene, the bounding shape is nowhere near its object, so it 
just doesn't see the object.
