This is the easiest thing I could think to do. I referenced the 144 points in by windowing all of them at once. And then I let Grasshopper sort them.
The list of points (looking at the sorted output of the key values) is sorted based on the distance from the origin to the point (or perhaps the magnitude of a vector...). To get a valid surface I had to shift all the points into the positive quadrant and move them far enough away from the origin. The U value is 12. There must be a smarter way to sort points referenced points, but David may have to chime in about that. http://groups.google.com/group/grasshopper3d/web/srfgrid_pts.png taz On Oct 9, 5:59 pm, oompa_l <[EMAIL PROTECTED]> wrote: > Hi Taz > > I just uploaded a file with some points > :http://groups.google.com/group/grasshopper3d/web/some-points-01.3dm > > there's nothing particularly meaningful about them - I constrructed > them for the purposes of this discussion.
