Generating predictable and convincing folds for leather seat design

Abstract

In this paper we describe a method for designing and visualizing folds in leather car seats. Since the manufacturing process cannot completely control the final result, an accurate simulation is neither possible nor needed; instead this tool functions as a sketchpad for the designer, and as a means for communicating the design as 3D model for design and production decisions. The method supports the designers' needs to create realistic looking folds and quickly and easily manipulate their position and appearance. For this, a minimal set of intuitive controls has been selected. The tool covers a range of realistic visual results for the designers and delivers the correct sewing pattern for production.
