As long as we're talking about reasonably large scenes (the whole scene
- sans earth - measuring meters and upward), just go ahead with the huge
sphere approach.


Make sure to keep the coordinate origin near the camera. Some people
have modeled entire solar systems with the sun at the center, and were
surprised when "portraits" of Deimos (or was it Phobos? one of the Mars'
moons anyway) showed artifacts. This is because absolute precision drops
as the absolute magnitude of coordinate values increases.
