It is indeed somewhat unnecessary in this case. But often a scene is
several 100,000 km wide. Just imagine a scene where the moon is visible,
which is 384,000 km (on average) away. Now of course you can just put a
moon-shaped disk somewhere in the air, but to me that's "painting" not
"raytracing". I am much more interested in building accurate models
than in producing pretty pictures.
