Simple Flat Origami Exploration System with Random Folds



In flat-foldable origami, design techniques represented by the circle-river packing approach are effective for complex models but are not suitable for simple models that can be made with a samll number of folds. In this paper, we propose an interactive system for exploring simple origami models by random generation of folded pieces. Our system generates dozens of tiny folded origami pieces and displays them at once. Every time the user requests another set of pieces, different shapes appear, because the generation process includes randomness. By selecting a desired model, the user can obtain the origami instructions to recreate it on real paper.


Circle-river packingに代表される既存の設計手法は複雑な作品に有効である一方、数回の折りたたみで完成する簡単な作品には適していない。本研究では、ランダムな折りたたみ形状提示による作品発見システムを提案する。システムは複数の折りたたみ形状を自動生成し、一度に提示する。ユーザは提示された形状を別の対象に見立てることで作品発見を行う。作品が発見できない場合は再度形状生成を行うが、この際、毎回異なった形状が生成される。目的の形状を選ぶことで、実際に折り紙で折るための手順を得ることができる。
