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 :<BR>

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.<BR>
And sorry if I flunk !<BR>
