Some of my early renderings Renderman (high school), Povray (college), and Art ( https://www.abemegahed.com/software/ - at the very end) were trying to visualize the scale of Rama and Ringworld.
replyThe scale of it was... well... astronomical.
Some of the ringworld covers were quite good.
replyOne of the things that I recall from that (and written about elsewhere... though I don't recall where) is that the shadows of the shadow squares, when viewed from the surface all subtend the same angle on the Arc of Heaven.
