[GRASSLIST:8228] Nviz problem

[Stefania Merlo]

I think I might be experimenting problems similar to Benjamin Ducke (July 
2005) with the visualisation of volumes in Nviz. I cannot visualise 
volumes!!! I tried with my own data and then with the Slovakia rainfall, as 
suggested, but nothing appears on the screen and this is the message I get 
on the Xterm. I am in fact using Grass 6.0 on macosX as wonderfully 
compiled by Lorenzo Moretti.

Can anyone help? My thesis is all about the use of GRASS GIS for the 
analysis and visualisation of archaeological data and it would be a real 
pity to be able to model but not display things.
