Also brought to mind Vista and VistaPro scenery generation / terrain rendering programs. Used to play with them a lot to produce pictures. Terragen is the only program I know of in that space these days.
This is the first thing that came to mind for me too! I loved VistaPro so much. I got a copy in one of those old programming books you used to buy with the CDs. It also came with PolyRay and some old-school VRML tutorials.
I had VistaPro with the Mars maps on my Amiga 2000 and 1200 back in the early 90s; I should dig those machines out someday (no idea if the floppies still work, tho - I have tons of Fred Fish stuff, too)...
Do it. Mars awaits! :)
Ah, memories! Sooo many hours playing with Vista pro and Mars.. :_)
