[GRASSLIST:7779] NVIZ and 3d vectors

[Jean-Denis Giguere]

Hi all !

If you go on the GRASS 6 homepage 
(http://grass.itc.it/grass60/index.php), you will find very interesting 
snapshots that represent 3d views of a digital elevation model plus 3D 
vectors (see http://grass.itc.it/images/grass51trees.jpg and 
http://grass.itc.it/images/grass51_nviz.jpg)

I can't find any documentation about how to import and/or create such 3D 
vectors and vizualize them into nviz. I would really appreciate if 
someone could point me a tutorial or a draft procedure to create this 
kind of image.

Greetings,


Jean-Denis
