Development of garment design system using random polygon pattern generator

Purpose This study aims to develop a random polygon garment pattern generator and a drape simulation system to automate the garment design process. Design/methodology/approach Garments were categorized into four groups based on the geometric features of the human body. Garment patterns in each group consisted of basic points, and the patterns were automatically placed, sewn and simulated around the body in three-dimensional space. Additional pattern manipulation functions were developed to modify the shapes of patterns by adding darts and cuts, either manually or randomly. Findings Users can produce new designs they had not considered before using the random manipulation functions. Since the three-dimensional simulation process is automated, users can focus solely on the design process. Research limitations/implications Garments composed of multiple layers were not considered. Originality/value This system differs from existing clothing computer-aided design systems in that even users lacking prior knowledge of garment design can generate various examples. It can help users understand the relationship between 2D patterns and 3D garments without the need for a pattern drafting process.
