Geometry
Crease Patterns and Paper Geometry
How fold lines encode geometric structure: Huzita–Hatori axioms, flat-foldability, and angle constraints.
Articles
Three articles covering crease geometry, fold mechanics, and modular polyhedral assembly.
Folding
Waterbomb Base and Pleating Sequences
The waterbomb base, accordion pleating, box pleats, and sink folds in sequence.
Modular
Modular Origami and Polyhedral Forms
Sonobe units, PHiZZ connectors, and the combinatorics of modular polyhedral assembly.
