[GRASS-user] Problems in 3D visualisation

[Yi Qiang]

Hi,

I've got a problem when I was following a tutorial in Grass wiki

http://grass.osgeo.org/wiki/Help_with_3D#Region_settings

I import the 3D volume ASCII file （vox_data50.txt） into Grass. Then I try to
see profiles in NVIZ. I set several constants. But I can only see a empty 3D
box with nothing inside.

I successfully followed the example of Slovakia 3D precipitation. It works
well and I can see beautiful profiles.

I don't know what the problem is. I also manually create some 3D ASCII
files. None of them can be properly displayed in NVIZ. For example, I import
the following 3D ASCII file into grass but failed to visualize it.
