Howdy folks. This is first effort in building a framework for generating planets
for a space-trading simulation I've been working on. The basic idea is to
parameterize what is needed and use the SDL to generate images for a wide range
of planetary bodies.

It looks good. Are you planning on including polar regions?

Thanks. I hope to. Polar regions, hurricane-like storm systems and some better
terrain generation are all on the table. I've been away from povray for a number
of years so this project is sort of a "relearning the SDL" again for me.

Nice.  I'm sure you're aware that projects like that can really suck you in,
especially when you're all fresh and full of energy.  ;)

(The long term idea was to make this an entire ground-level detail planet, fully
customizable, and with zoomable camera views to both adapt and limit the LOD
based on distance from the camera.)

I'm currently up to my ears in sorting out some RL stuff, so I haven't gotten
back to any of the old projects or gotten sucked into any of the many new
projects that are lined up... ;) :D
Hopefully some of that provides you with some ideas and inspiration - it will be
nice to see another approach to this topic.  Good work so far.

Thanks. Looking back, I must have started this project back around '93-'94 on my
286 running DOS/Win3.1. Where does the time go? I remember converting an image
file from fractint to a heightfield and it took over a week for the 286 to crank
out simple "flyby" frames. I was hooked right then and there.

Thanks for the links. I'm always interested in learning new stuff.

I understand completely. Right now a home remodel/redecorate is siphoning off
more energy from my other projects. :) Retirement has afforded me *** LOTS ***
of free time which my wife lays hold to at times. ;)

This image is bit more refined, moving the land, Sea and Sky layers to their own
spheres. The problem I found is the interaction between the filtering in the
color_maps can create anomalies that I don't want. Tweaking the color_maps and
added normal blocks too.
