Interactive simulation and design of yarn-level cloth patterns
Abstract/Contents
- Abstract
- Modern design tools for yarn-level cloth patterns struggle to predict the final shape of knit or woven fabrics. My work describes an interactive design tool for authoring, simulating, and adjusting yarn-level patterns for knit and woven cloth. To achieve interactive performance for notoriously slow yarn-level simulations, I use two acceleration schemes: (a) yarn-level periodic boundary conditions that enable the simulation of only small periodic patches, thereby exploiting the spatial repetition of many cloth patterns in cardinal directions, and (b) a highly parallel GPU solver for efficient yarn-level simulation of the small patch. My system supports interactive pattern editing and simulation, and runtime modification of parameters. To adjust the amount of material used (yarn take-up) I support "on the fly" modification of (a) local yarn rest-length adjustments for pattern specific edits, e.g., to tighten slip stitches, and (b) global yarn length by way of a novel yarn-radius similarity transformation. I demonstrate the tool's ability to support interactive modeling, by novice users, of a wide variety of yarn-level knit and woven patterns. To validate this approach, I compare dozens of generated patterns against reference images of actual woven or knitted cloth samples, and I released this corpus of digital patterns and simulated models as a public dataset to support future comparisons. This work has served as the foundation for two other collaborative projects, including improving yarn-level cloth renderings via macro-fibers simulations, and a design tool for 3D woven materials. Finally, to avoid regenerating yarn curves for each pattern edit, I provide a method for live pattern updates in order to support interactive design of complex fabrics.
