Think of it like this: to see if the light is 'shadowed' or not, a ray is shot away from the surface (in the opposite direction of the light); if it hits something, the light is shadowed.

But I thought if they have no origin, then everywhere is an origin - as if all points in space were spontaneously generating photons all the time and shooting them in the same direction. So I don't immediately understand why a celestial sphere that accepts shadows would turn all the lights off. I'll assume it's more a matter of programming than philosophy and check the shadow box.
