From the POV-ray documentation:
8<----------------------------------------------------
Appendix F.5 Height Field Tips
Try using POV-Ray itself to create images for height fields:
camera { location <0, 0, -2> }
plane { z, 0
finish { ambient 1 } // needs no light sources
pigment { bozo } // or whatever. Experiment.
}
That's all you'll need to create a .tga file that can then be used as
a height field in another image!
8<----------------------------------------------------
There are also other programs available, I have been playing a little
with
TERRAIN MAKER by Eric Jorgensen. It's an old DOS program, but it can
make some really impressive height fields, plus You have editing
abilities, so You can make a flat part where You want it, and add to a
mountain.
Unfortunatley I don't remember where I found it :-(
It could have been a link from http://www.povray.org, or from
http://twysted.net
Search around a bit, and I'm sure You will find it, otherwise, mail me
and I'll send You the .zip file.
