There is one region for each seed, consisting of all points closer to that seed than any other. Bands; Timetable; Directions. Hi Marinus, If a Multi curved surface is a double curved surface, then you can create the voronoi on a flat rectangle bellow or above the surface. At the moment i have something too "regular" for me. The first being a UV mapping method in which points are seeded on the surface and mapped to the XY plane where a voronoi diagram is generated and then these curves are then mapped back onto the original surface. Hand-drawn and digital diagrams can also be digitized and used in order to describe certain parameters for design formation. gh, the Grasshopper file to generate these types of things) What's a Voronoi?
