[GRASS-user] Problem 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 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 see its profiles. I was working with Grass on WinXP SP3.

Is anyone can tell me what the problem is?

By the way, when I type g.region rast3d=[name], it always display:
G3d_readWindow: unable to find [C:/.../PERMANENT/grid3/vox_data50/cellhd].
