One of the most popular shapes in topology studies is the one-edge, one-face Moebius stripe. Here is a basic definition that generates Moebius-like lofted surfaces. I say Moebius-like, because in Grasshopper, or Rhino, or in any NURBS surface method, I couldn’t manage to model this shape in it’s real topological singularity. Tricky part of this Grasshopper definition lies at the end, as I take first segment of the surface, flip it and attach it to the end of the segment list. This creates an illusion that the loft operation seem […]
