  Have you seen Glenn McCarter's IRTC entry, "dpatrol.jpg", from the
Jan-Feb 1998 "Great Engineering Achievements" topic? His scene features
the Great Wall of China, with a view extending to the horizon. I'm
looking at it on my IRTC CD-ROM Year Three (shameless plug). Glenn used
separate height fields for each mountain but used sPatch to create the
Wall itself. I'm not sure how he achieved placement of the Wall and
guard towers. He was using POV-Ray v3.0.
