Languages for 3D Industrial Knitting
summary
Claim: current machine control languages are brittle and low-level. Implementation: a SIGGRAPH 2016 compiler takes declarative tubes and sheets and emits NitPaint for a Shima whole‑garment flatbed with ~600 needles and two beds, compiling down to an assembly of knit,tuck,transfer,split primitives. Algorithm: a dynamic‑programming collapse–stretch–expand transfer planner that is provably complete (but currently inefficient). Tooling: a JavaScript library (Nancy) and examples — gloves, a stuffed bear and a snake — successfully knit from generated instructions.
