Hi Aswin,


did you start NVIZ from the command line or from the menu?

after checking the region bounds/resolution with 'g.region -p' make a raster
surface to put it on.

  r.mapcalc zero=0

from the command line start NVIZ with

  nviz -q

then load the raster surface and the 3D vector manually.
You may want to set the raster to be transparent.


does that help?
