This is a simple program to compute how far an observer must travel from a
visible object (such as a bright light at night) before the object is obscured
by the curvature of the Earth. The program allows one to select the amount of
desired curvature required (called "Earth bump" in the program - this is
illustrated when the program is run). An example output image is posted in the
povray.binaries.images section.

Kind regards,
Dave Blandston

I forgot to mention this but if anyone wants to experiment with this there are a
few variables to set. They're clearly documented and positioned near the
beginning of the file.
