Abstract:

In this paper, we propose a CAD system that supports drawing diagrams of flat-foldable origami pieces. Our system predicts possible folds that can occur in the current state of an origami piece and lists these candidates. This prediction is made based on the first four axioms of the Huzita-Hatori (Huzita-Justin) Axioms, a series of seven basic methods for folding a sheet of paper by referring to points and lines. All possible folding lines are generated by applying these axioms in our system, and then valley folded shapes are calculated and listed as candidates for the next step. When the user selects one of these candidates, the shape is automatically appended to the origami diagram as the latest step.

概要:

Software is available for Windows (zip). This software requires Java Runtime Environment. Save/Load is not supported, but you can export a diagram separately as png/svg/eps. Prediction feature is ON/OFF when sub-window is Open/Closed. [CAUTION] Please note that this software is under development. The system may takes a long time to calculate predict-candidates in the later steps.
ソフトウェアを公開しています。 for Windows (zip). 実行にはJavaランタイムが必要です。ファイルの保存/読み込みはできませんが、折り図を1つずつ出力することはできます(png/svg/eps)。予測機能はサブウィンドウが表示されていれば有効であり、表示されていなければ無効になります。 [ご注意] 本ソフトウェアは開発段階です。ステップ後半では予測候補の計算に長時間かかる恐れがあります。
