I had a question yesterday about the creation of 3D vector objects in GRASS. I’ve seen screenshots of them (the dinosaur and water tower), but don’t have any idea on how to create them. I thought there was a tutorial on the WIKI, but the only thing I found was Jachym Cepicky’s perl module for 3D trees—with the explanation in Czech (I think).
I’ve scanned the docs, tutorial pages, and other documentation pages to no avail. So, can anyone point to a reference that tells how to create those nifty 3D vector images?
Thanks
Michael

Both dinosaur and water tower were originally DXF/DWG files.
Procedure:
- v.in.dwg
- v.transform (to geocode the XY DWGs, also z scaling)
- nviz
The houses were hand drawn.
For nifty trees, try
