if I'm not wrong, I took it from
http://mpa.itc.it/grasstutor/data_menu2nd.phtml
the date of the set should be
-rw-r--r--   1 jachym jachym 8,9M 2005-02-07 09:11 slovakia3d.tar.gz

g.region -3p gives
projection: 0 (x,y)
zone:       0
north:      5530000
south:      5275000
west:       4186000
east:       4631000

bottom:     0.00000000

and no volumes are drawen. when I move with the viewpoint, the volume is showen
like 2D-vector area (not 3D-vector cube).

when I set the 3D resolution value g.region -d, then it worked
g.region -d3p
projection: 0 (x,y)
zone:       0
north:      5530000
south:      5275000
