Loading raster map <elevation.dem@PERMANENT>...

nviz_cmd seems to work on my machine (grass6/grass7).

g.region rast=elevation.dem
nviz_cmd color_map=elevation.dem elevation_map=elevation.dem output=image
identify image.ppm 
image.ppm PNM 640x480 640x480+0+0 DirectClass 8-bit 900.014kb 0.070u 0:02

Probably better looked at with other wxPython issues rather than old NVIZ (TclTk? and C++) issues.

is this still valid ? It works for me in grass65, mybe it applies only to grass7 and milestone should be changed then?

nviz_cmd JRxytz9908_4mt60_00006 mode=fine resolution_fine=1 output=jr3d_nvizcmdtest format=tif size=300,300

GRASS 6.5.svn > gdalinfo jr3d_nvizcmdtest.tif

Driver: GTiff/GeoTIFF Files: jr3d_nvizcmdtest.tif Size is 300, 300

the result is the same with ppm format

Resolution: fixed
Status: newclosed

Tested in GRASS 6.4.svn:

GRASS 6.4.3svn (spearfish60):~ > g.region rast=elevation.dem -p
GRASS 6.4.3svn (spearfish60):~ > m.nviz.image color_map=elevation.dem \
      elevation_map=elevation.dem output=image

... output is fine.

The same for GRASS 7.svn. Closing as fixed (recently some fixes have been applied to m.nviz.image).
