I know but that leaves a cheat-y feeling.

Yes, but it is unavoidable as you have to deal with extremely large 
objects (the Ring) together with a detailed scene around the camera. The 
two just don't fit together in the same physical model where POV-Ray is 
concerned without serious artefacts. And it is hardly necessary: the 
Ringworld experience for an observer would be something like watching 
the Moon in our sky, disconnected from the immediate world he/she lives in.

Still one of my references where Ringworld-building is concerned.

What you say is so true.
I wonder how fast and at what elevation the ring arch would converge to 
a line.

No one's ever made a Discworld, have they?

The attached image is one of my early tests of the true scale Ringworld 
model, with the shadow squares left out. It does not show the zenith but 
you can partly extrapolate. It shows nicely I think why the Ringworld is 
called the Arch by the natives.

Not that I remember. I think I wanted to start once, intending to use 
elephant models of course, but it never got off the ground somehow.

A key part of "science fiction" is "science."

I get a similar view. I did an animation tilting the camera to the 
zenith. (The camera motion is not very good.)

Making the topography would be interesting.

LOL True(ish) :)

There is always the Science of Discworld.

And the rim. An interesting animation would be as viewed by the Fifth 
Elephant. :-
