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

[Slover, Kevin]

Robert,
  And am sure that you have checked this, but is coming from a person
that saw the same thing as you have...

When starting NVIZ from the command prompt, do you see any error warning
from TCL/TK??  I had to link the libtk8.4.so and libtcl8.4.so libraries
from /usr/local/lib to /usr/lib.  When doing this, it resolved my
issues.

Search the archives, using libtk8.4.so and nviz I think, and it comes up
with a few threads on this...

Might be more on the basic side, but always check to make sure things
are "plugged in" properly...

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
