Figure 1: Our system allows novices to create a variety of custom jewelry. Following aesthetic and fabrication principles, our algorithm decomposes an input line drawing (a) into smooth, well-connected paths that cover each line in the drawing exactly once (b). We extrude support walls inside the sharp turns of the paths to create a physical jig that guides wire wrapping (c). Assembling the three wires of this design yields a butterfly pendant (d). Wire wrapping is a traditional form of handmade jewelry that involves bending metal wire to create intricate shapes. The technique appeals to novices and casual crafters because of its low cost, accessibility and unique aesthetic. We present a computational design tool that addresses the two main challenges of creating 2D wirewrapped jewelry: decomposing an input drawing into a set of wires, and bending the wires to give them shape. Our main contribution is an automatic wire decomposition algorithm that segments a drawing into a small number of wires based on aesthetic and fabrication principles. We formulate the task as a constrained graph labeling problem and present a stochastic optimization approach that produces good results for a variety of inputs. Given a decomposition, our system generates a 3D-printed custom support structure, or jig, that helps users bend the wire into the appropriate shape. We validated our wire decomposition algorithm against existing wire-wrapped designs, and used our end-toend system to create new jewelry from clipart drawings. We also evaluated our approach with novice users, who were able to create various pieces of jewelry in less than half an hour.
Closer to our goal is the work of REF , who decomposes a line drawing of a jewelry piece into a small number of paths suitable for fabrication with metal wires.
