Subject: NVIZ fails to display 3D polygons

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: grass-6.0.cvs_src_snapshot_2005_01_22

NVIZ doesn't display 3D polygon properly. Visualisation with 3D polygons is impossible.
Details:

nviz elevation=dem vector=drzewa_3d

After the second press of DRAW button in NVIZ my DEM becomes almost 
completely black. Any raster overlay is invisible.

Radim's sample dataset does it too (house_roof,house_wall polygons).

The 5.7 snapshot from 2003_10_04 does not have this problem!

There was a related fix in lib/ogsf/

2005-02-03 15:28  markus
        * Gv3.c: fix for areas, now 2D polygons visible as boundaries again
        (3D areas should be visible as filled polygons)

Please try with a newer GRASS 6 version.

Hope this helps

I did grass-6.0.cvs_src_snapshot_2005_02_12 and the problem remains.

And another one arose: it is only possible to change the color of the area 
itself - the borderline is always black. Could it be possible to define the 
color of the borderline and area separately?

Unfortuantelly it doesn't. But thanks for your care.

Cheers,

ahh, now I see - you meant March and I thought you were reffering to 
February

sorry for my absent-mindness but it would be better to follow one scheme of 
dating fro the sake of clarity
