Geometry
Crease Patterns and Paper Geometry
How fold lines encode geometric structure, from the Huzita–Hatori axioms to the constraints that govern flat-foldability.
Origami & Geometry
Folding Sequences and Paper Geometry
A structured look at how flat sheets acquire three-dimensional form through crease patterns, fold sequences, and geometric constraint.
Articles
Folding topics
Three areas of paper geometry covered in depth: the logic of crease diagrams, the mechanics of pleating, and the combinatorics of modular assembly.
Folding
Waterbomb Base and Pleating Sequences
The waterbomb base as an entry point into radial symmetry, followed by accordion and sink folds used in tessellation work.
Modular
Modular Origami and Polyhedral Forms
Sonobe units, PHiZZ connectors, and the combinatorial logic behind assembling identical modules into stable polyhedral shells.
