The longer I think about this "Delaunay-cloth" idea, the less plausible does it seem to me. Most real cloth I've heard of is either woven or knitted, which means it is in fact based on a rectangular grid. I think the the 'cross-hatch' pattern that LaurieA showed earlier makes much more sense than willy-nilly randomization. I may be wrong, but I'd like to see some proof that random meshes perform better than that particular pattern, not just a straight rectangular grid.
