Brent, I'm not quite certain what you are trying to do (I have this funky version of Grasshopper going at the moment), but as a suggestion it might be easier to try to create triangular surfaces rather than meshes.
I set the file up with meshes so I could add pretty colors but meshes are tricker to work with and learn to use. Basically the sorting routine finds all sets of 4 points (the 4 "Cull" components stacked up) in a 0-1-13-12 (for example) clockwise rotation (or counter-clockwise, I don't recall) going from position to position in rows from bottom to top (or something like that). The verticies of the subdivided surface are ordered 0-1-2-3-4-5-6... consecutively in rows from bottom to top (I think). You could use "Srf4Pt" to define any kind of triangle (the 4th point is optional) depending on the order you connect 3 of the 4 "Cull" results into it. If you're trying to make a diamond-like pattern you could also try culling the "Cull" results to create back to back triangles and then boolean "Union" things together. If you're trying to do anything funkier like reversing or shifting lists you're going to have to be careful to track the vertex ordering as you go along. I don't know if any of that background is useful, but I hope it helps. taz On Sep 16, 10:23 am, BrentWatanabe <[EMAIL PROTECTED]> wrote: > Not sure how you link files into these posts... > > But I have a few questions. > > I took a look at Taz's Tri Mesh sort and I modified it to shift over 1 > point over, essentially removing the divided quad aesthetic.
