I was very interested in your original email, so I tried to track down

authors are unwilling to release the software into the public domain. I 
have not specifically tried NVIZ visualization as you describe, but I 
think the 3rd Ed. of "Open Source GIS: A GRASS GIS Approach" covers how 
to create 3D vectors which can be brought into NVIZ to produce what you
