G3D modules and s.vol.idw

[Bernhard Sturm]

Hello to everybody
I just compiled GRASS5b7 as I was very keen on the newly now implemented G3D
modules. I tried s.vol.idw (as s.vol.rst is not yet implemented in the
official release) in order to run an interpolation on a 3 dimensional site
file (x|y|z|%w). However I ran into some troubles:
I couldn't import (s.in.ascii) my sites. Although my ascii file with the
site information looks like the new specified site format
(http://www.geog.uni-hannover.de/grass/gdp/html_grass5/programming/sites-api
/index.html), but GRASS couldn't read the file properly (warnings were
printed) and only the first line of the file was read. Do I need header
information in the ascii file, or does s.in.ascii not properly import ascii
site files?
And for the G3D part: will s.vol.idw produce a raster file that can be read
by the standard 2d GRASS modules? (such as d.rast)

Thanks for your support
