Modular origami. Modular origami or unit origami is a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than would not be possible using single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together. Definition and restrictions[edit] Examples of modular origami made up of Sonobe units Modular origami can be classified as a sub-set of multi-piece origami, since the rule of restriction to one sheet of paper is abandoned.
However, all the other rules of origami still apply, so the use of glue, thread, or any other fastening that is not a part of the sheet of paper is not generally acceptable in modular origami. More than one type of module can still be used. History[edit] Types[edit]

In all chaos there is a cosmos, in all disorder a secret order About this page: This page will detail how to make four different types of mathematical shapes by producing and assembling a number of tiny paper pieces.
I did not invent the pieces or the method of making pieces; in fact, they seem to be called "Sonobes" (though I've always called them "pieces" and will do so here). Here is a rather detailed page that shows pieces that resemble mine. I also did not invent three of the models presented on this page. The Epcot Ball! Preliminary instructions: As I said, these models are all made up of a number of absolutely identical paper pieces.
Paper type and paper size: Unlike for the fighter jet paper airplane, I strongly recommend that you use lined filler paper for these models. Accuracy issues and making the squares: Basically, all the rules that apply to my paper airplane instructions apply here. Folding a single piece: A completed piece. A freshly cut square of paper. Okay. Okay. Good. 1. Origami modulaire. Mathématiques des origamis. Un article de Wikipédia, l'encyclopédie libre. Les pliages d'origamis sont utilisés en mathématiques pour procéder à des constructions géométriques. Selon les méthodes de pliages utilisées, on obtient des procédés plus riches que ceux propres à la règle et au compas. Formalisation des origamis[modifier | modifier le code] Le formalisme auquel il est le plus souvent fait référence est celui de Huzita. Il contient 6 axiomes qui sont en fait les 6 pliages de base permettant de décomposer n'importe quel origami.
En voici la liste : Axiome 1. Les axiomes 1 à 4 ont toujours au moins une construction possible, unique pour les axiomes 1, 2 et 4. Points, droites et nombres constructibles par origami[modifier | modifier le code] On se donne deux points de base. On appelle nombre constructible par origami un nombre égal à la distance de deux points constructibles, les deux points de base étant à une distance unité. On peut alors interpréter les axiomes 1) à 4) de la façon suivante : ou mais ni de ni de . Origami Cube. What is the Origami Cube?
The origami cube is a cube you can fold from a square sheet of paper. Another name is water bomb.
