[GRASS-user] NVIZ grass6.1 cvs, crash

[Robert Kringel]

Dear all,

We are currently running grass6.1 CVS-Version (20/05/2006) compiled
for a Pentium IV running under Suse Linux 10.1. The Computer has a
i845 Intel-onboard graphics chips. The Xserver uses the module i810.
Everything seemed fine.

we are working mainly with the r3.modules to visualize contamination
clouds interpolated with v.vol.rst. Trying to visualize volume-maps
crashes NVIZ in three ways.

1. calling NVIZ from gis.m produces 2 Windows, which soon dissappear
without further message

2. calling NVIZ from the grass prompt with "NVIZ &" and adding a 3d-map
immediately crashes NVIZ

3. calling NVIZ from the grass prompt with "NVIZ &" without data, loads
the NVIZ program. NVIZ also loads the 3dmap, trying to set an isosurface
seems to work, but visualization fails. The program does also not show
the usual frame.

A hint would be highly appreciated:

-- Is 3d acceleration mandatory for work with NVIZ ?
-- could this be a missing graphics-library?
-- Are there any known problems with NVIZ (separate setup,
 do I have to recompile)
-- How can I stop this behavior?

best regards,

Robert
