I'm catching up your discuss in a hurry, but if it can help, for a couple of weeks I've been using r.surf.nnbathy to generate TINs : http://www.mail-archive.com/[email protected]/msg00891.html I turn my vector 3D points into a raster, then make the interpolation (with the 'l' option) with r.surf.nnbathy, it works fine for me. And sorry if I flunk !
