VIDYA NARAYANAN, Ph.D. Student http://www.cs.cmu.edu/~nvidya/3D Machine Knitting
Industrial knitting machines are commonly used to manufacture complicated shapes from yarns. However, designing patterns for these machines requires training and machine knitting expertise.
In this talk, I will introduce machine knitting, discuss machine knittability of arbitrary 3D shapes and introduce our new design system -- a general visual programming interface for creating 3D objects with complex surface finishes on industrial knitting machines. At the core of our interface is a new, augmented stitch mesh data structure to represent machine knittable patterns. The augmented stitch mesh stores low-level knitting operations per-face and encodes the dependencies between faces using directed edge labels. Our system can generate augmented stitch meshes from 3D models, allows users to edit these meshes in a way that preserves their knittability, and can generate machine instructions by scheduling the execution order and location of each face for fabrication. I will present knitted results fabricated on an industrial knitting machine using our system to demonstrate the flexibility of our pipeline.
