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.

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

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.

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

It would be easier than a Ringworld from ground level. The animation
above was taken at 3 million kilometres above the ground.

So, approximately 509.8 million HemiDeciFeet.

Always strong, when I can get it.
Usually black - though taking the time to prepare a proper Café au Lait
(Milchkaffee) can be a real treat - the scalded milk has a flavor that I'm not
sure can be replicated any other way.
Gotta have sugar. Caffeine is just the foot on the gas pedal. The sugar is
what feeds the engine.
Otherwise I get the shakes. :D

Just use a plane as the ground, then, use another render of the ring
itself as a background.
If standing near a side wall, use a very long box on that side.

The movie is not as good as the various books of that amazing SciFi

It has many advantages over a ring and in The Culture universe created
by Iain M. Banks, orbitals are very popular.
