Here are two utilities to generate round things (ORB) and cylindrical
things (CYL) to be rendered with the POV-Ray raytracer (or other program).

You first need a heightfield, for instance one generated by "gforge" or
"HF-Lab", programs which should be available from the same place you
obtained this file.  You then convert the heightfield into a bumpy orb
or cylinder with the respective program, which outputs a large number
of triangles in "raw" format, or using POV syntax. Note that there is
no "union" or "mesh" grouping in the .inc file itself, you have to provide
that in your .pov file (see the examples).

Type "orb" or "cyl" with no arguments for a brief explanation of how to 
use them.
