The landscape is described as having the same variation as the surface of any
planet - indeed, the maps of the other worlds from known space are all there,
Mars being a plateau raised by some km to simulate the thin atmosphere. The most
interesting lighting conditions will probably be evening/night-time - the
brightest archlight should be cast from the few next/previous days to
spinward/antispinward.

To be honest, the best way of doing this is probably to pick your position
across the ring width, render a spherical camera view with nothing on the ring
floor, then just use it on a sky sphere/light probe for the landscape scene of
your choice. Not as satisfying, unfortunately... :(
