Origami, Paper folding, and e-Origami

News: On March 27, 2023:  Eos. was released. 

It is a replacement for Eos3.7.1 which was released on March 17, 2023.

News: On March 17, 18:10, 2023:  Installer.nb was missing in the March 15 edition of Eos.3.7.1.  EosLoader.m has been changed because of the difference of $ContextPath between our development systems (MacOS (M2), MacOS((Intel), and Windows 11. Eos3.7.1  for Mathematica 13.2.0 runs on those three types of operating systems.
Please reload the new edition of Eos.3.7.1

News: On March 15, 2023: We replaced Eos3.7.1 with a new one. Reload this edition. A function to use g3 package is missing in March 14 edition.  We need this edition when we construct art origami.

News: On March 14, 2023: We changed the code responsible for reading Eos packages. We thus avoided the problem pointed out on March 12. We replaced Eos3-7-1.zip with the new one. We need to use Needs[“Eos`”,”EosLoader`”] instead of << EosLoader` to load the Eos system. <<EosLoader` still works, though.

News: On March 12, 2023,  Eos3.7.1 has been published on the page Eos Software -> Eos3.7. It is tested on  Mathematica 13.2 running under macOSX 13.2.1.

Important: On  March 12, 2023, a new release of Eos, i.e., Eos3.7.1 will be published on this website.  Please replace your Eos3.7 with Eos 3.7.1. Eos3.7 will expire on March 31, 2023.

News: 2023 January 24: Eos 3.7 has been tested on the newly released Wolfram Mathematica 13.2 (Japanese version). Eos3.7 runs on macOSX  Ventura 13.1 and Windows 11, “basically.” See the post of 2023/01/ 24 for more technical details.

News: 2022 December:  Eos3.7 has been released. We restore the rules of using this site and Eos software to those before April 15, 2022. Anyone can register now.  Please read Supplement for Math 13 (new). 

News: 2022, Oct. 18:Tetsuo Ida is one of Wolfram Innovator Award recepients.

Origami, the art of paper folding, has attracted people’s minds for its beauty and utility in everyday life. Origami has also been the scope of mathematical studies. The folding operations are simple, easily realized by hand, but powerful enough to solve cubic equations. Origami is regarded as a powerful geometrical tool allowing constructions that classical Euclidean tools could not make.

E-Origami System  Eos

The computational origami system Eos is designed to study the mathematical aspects of paper folds. It includes capabilities of modeling fold operations by algebraic and symbolic methods, computer simulation of origami construction, and proof of the correctness of the constructed origami. Eos is developed by members of Symbolic Computation Research Group (SCORE), department of computer science of the University of Tsukuba.

Eos3.32 was released on March 23, 2021. It runs on Mathematica 12.2.

Eos3.4 was released on May 6, 2021. It runs on Mathematica 12.2.

Eos3.5 was released on January 20, 2022. It runs on Mathematica 13.

Eos3.6 was released on July 19, 2022. It runs on Mathematica 13.

Eos3.7 was released on December 16, 2022. It runs on Mathematica 13.1.
