[GRASSLIST:7794] Re: NVIZ and 3d vectors

[Michael Barton]

There are some folks here at ASU who are interested in doing this kind of 3D
generation. 

It would help, I think if we could at least see what the ascii files are
like that generated the tower and houses, and the tree algorithm (if
different from Jachym's perl script in the WIKI).

Thanks
Michael
