[GRASS-user] v.to.rast3 - no output

Hi,

I'm trying to get a 3D raster from vector points. The points have a Z
column in the attached database table, but v.to.rast3 is producing
nothing - there is no output map, but neither is there any error message.

Running Grass-GIS 6.3 on OpenSuse 10.3.

Is there a bug I'm not aware of?

in grass 6.4

v.random p n=1000 -z zmax=100 --o

v.to.db p opt=coor columns=x,y,z
v.db.select p col=cat,z

g.region vect=p -g3 res3=100
v.to.rast3 in=p out=p3 column=z
r3.info p3 -g

north=229162.905764

east=640957.677618
west=636085.786709
bottom=0.0316625
top=99.9666

seems to be OK. Martin

Thanks, Martin. A supplementary question, if I may: how come I can't
find the output raster to display? It doesn't show in g.mlist ...
