Subject: NVIZ volume polygon resolution error

Platform: GNU/Linux/i386
grass binary for platform: Compiled from Sources
GRASS Version: 5.7.0 weekly snapshot from 12-25-04

Currently there is some kind of threshold regarding the polygon-resolution 
when displaying volumes in NVIZ. 
 
If the resolution is set under a magical critical value NVIZ just dies. 
Unfortunately no error messages are given, but this performance is easily 
reproduceable. 
 
I am currentlty testing NVIZ-volumes on a xy-location: x=40, y=40, z=18, 
x-y-z-resolutions are all set to 1. The volumes fill at max a third of the 
possible volume space. 
 
The phenomenon is independent from the size of the NVIZ-"monitor". 
 
The problem is particularly annoying since the first polygon-resolution set 
by NVIZ after a new layer of volumes has been created seldom shows all 
detail. Therefore the polygon-resolution has the be counted down by the 
user, which renders more detail until the the described error is (once 
again) encountered.

Hi Peter,

Could ou verify if this problem is still reproducable in 6.1?

Hi Maciek, 
 
the bug is alive and well. Unfortunately. 
I also noticed a lot of strange behaviour regarding animations in NVIZ 
(mispositioning) :-/ 
 
Cheers, 
Peter
