Hi, I wanted to know which functions are useful for making Scoubidou stitches like in these pictures:
Pretty. Also why it sounds like Scoobie-do? Lawsuit IMO. Graphics-wise I would try using Tube in Graphics3D along with an infinite perspective, then maybe some kind of edge detection if the tubes are too curvy, or maybe just a Glow setting to prevent the tubes from being shaded. In terms of the geometry itself though I don't know. It seems you could use a grid-based approach. Good luck.
