Thanks Carlos,
Your version works fine but I had to use the Hamish trick posted at
http://www.nabble.com/do-not-export-categories-with-v.out.ascii-t4142590.html
v.out.ascii input="${VECTOR}" format=point dp=3 | cut -f1-3 -d'|'
| tr '|' ',' > $TMP.${PROG}.input_xyz
because the fs (field separator) option is not available in the
GRASS-6.2.2 version of v.out.ascii that I am using.
Kind regards,
Luigi

Luigi (and everyone else)
can you try this version?
I must be going crazy or something. Apparently, I did the changes in
r.surf.nnbathy back when I started that thread you cited, about a
month ago.. but I forgot to test it and submit it..
I did a fast test here and it worked fine, with a 3D vector points layer.
hope it works!
cheers

Carlos: Thanks for your prompt reply.
I am using r.surf.nnbathy 1.9, 2007.01.02, and if I don't enter any raster
name, it complains:
ERROR: Raster map not found
How can the script work if I don't give it an input name? I did not
understand what is the "second option" you mentioned in your message, so I
am asking whether the following command line corresponds to what you mean:
r.surf.nnbathy input= output=3D_vector_name alg=nn
Sorry for my bad intuition and thanks again,
Luigi

Luigi, I just went to look at r.surf.nnbathy, and we _can_ use it to
interpolate 3D vector points.
just don't enter any raster, and use the second option, for a 3D vector.
works well, and it is fast.
cheers

Dear list,
Is there any working version of v.surf.nnbathy around? From this recent post
http://www.nabble.com/do-not-export-categories-with-v.out.ascii-t4142590.html
it did not sound like an impossible thing. I am looking to replace
v.surf.idw with a more robust interpolation method (natural neighbour?)
in my mapping routine -- my input is scattered 3D vector points. I am
just checking to see if somebody else already did it before trying to
modify r.surf.nnbathy myself (I am not really a programmer).
Thanks and regards,
Luigi
