[GRASS5] [bug #2991] (grass) NVIZ fails to display 3D polygons

this bug's URL: http://intevation.de/rt/webrt?serial_num=2991
-------------------------------------------------------------------------

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!

        * Gv3.c: fix for areas, now 2D polygons visible as boundaries again
        (3D areas should be visible as filled polygons)

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

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?

Hope this helps

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

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
