TINs are just xyz points joined together, e.g. with v.delaunay.

I had thought there was a script on the wiki add-ons page, but I don't
see it there now. (to do v.delaunay + v.distance to apply elevation
value to triangle centroid?) Maybe google could find it.

r.refine, again from Laura Toma's group:


also, in the GRASS 6 vector lib there is lib/vector/Vlib/tin.c. I don't
really know what it does, but d.what.vect calls it.
