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.
