In the first image, the portal is the sphere in the middle...the "far
end" of the portal is just a larger sphere surrounding the scene.
The second image is a small, closed room with a portal to an open area.
The room is lit entirely by light from the portal. As you see, no direct
light can pass through the portal...one of the limitations of my patch.
