Thanks, Leroy!

I tried to make the LUNEX script simple to use so users wouldn't have to write
much code, just change a few numbers.

Mastering the spherical iso-surface with a height field was a nightmare at first
and for the entire moon and took forever to run a large rendering.  That was
half a year ago when I had a single 2.7 GHz CPU system with only 8 gigs of RAM.
It tooks hours to get a nice full-screen rendering when I first started.

Fortunately, I recently upgraded to a fast 6-core high-end graphics system with
lots of RAM and can now render images in a reasonable time frame.  Pictures that
used to take hours to render six months ago, can now render in a few minutes.
Big improvement.

I got many of my lunar texture maps from:

Here's a nice map for Jupiter too:

I've also been wanting to do a similar program for Mars but can't yet find any
Mars maps comparable to the quality of the lunar texture maps.
