Origami, the art of paper folding, has attracted the minds of people for its beauty and its utility in everyday life. Origami has also been the scope of serious mathematical studies. The folding operations are simple, in the sense that they are easily realized by hand, but powerful enough to solve cubic equations. Therefore, origami is regarded as a powerful geometrical tool allowing constructions that cannot be realized by Euclidean classical tools.
E-Origami System Eos
Eos3.32 is released on March 23, 2021 . It runs on Mathematica 12.2. Please read Supplement for Mathematica 12.2.
Eos3.4 is released on May 6, 2021 . It runs on Mathematica 12.2.
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 University of Tsukuba
