hi, all
I am a beginner GRASS user. I want to generate 3D subsurface soil for my
thesis, but i have some problem in GRASS.
I had created vol. by s.vol.idw then use r3.mkdspf to make a display file
(mymap@PERMANENT) but when i use r3.showdspf, it show "ERROR: Not able to
find display file for [dspf]".
I use grass5beta11.bin.linux for i386. Do i make some mistake concept (site
data -> s.vol.idw -> s.vol.idw -> r3.mkdspf -> r3.showdspf)?
sincerely yours,

There's a bug in the naming of the output file from r3.mkdspf. It'll be
there, just not named as you specified (has some extra junk added). If
I'm remembering correctly, if you go into the grid3 directory under the
mapset and move the dsp<semi-random junk> directory to "dsp", everything
will function normally thereafter (including creation of new dspf
files). I may have misremembered, but it's something like that...
In general, the grid3 modules are not well supported at this time (and
will not be in GRASS 5.0).

First a recommendation: There are severe problems in s.vol.idw, you
may use s.vol.rst for volume interpolation.
Generally your procedure is correct. If you start r3.showdspf interactively,
you should be able to list the display files (currently I don't have it
compiled so that I cannot test it).
Consider to run
r3.out.v5d -> vis5d to visualize volumes.
Probably the r3.mkdspf didn't run properly? Any error messages there?
Please be aware that there are severe bugs in the G3D library (therefore
these modules won't appear in the next binary release any more unless
someone looks at it).
