wait im confused, why a torus and not a sphere?

  Going around the "top" of a sphere ends up looking weird in a 2D projection (like your standard Mercator projection map) - you end up next to where you went in. If you want to come out on the bottom, you typically want a torus.

    What if it was a sphere, but the camera moved along with the ship -- with a dead zone in the middle?

  (nbodyphysics here) I initially had the same thought, but when you think of a Mercator map, the top edge is a point, the north pole. On a torus it's a line, the inner circle.

    The other comment makes an excellent point about the mapping. That's also crucial.
