Kokichi Sugihara is a Japanese mathematician and artist, a master of 3D optical illusion. Permanent winner in the worldwide optical illusion competition: first place in 2010, 2013, 2018 and 2020, second place in 2015 and 2016.
His interest in illusions stems from his research in the 1980s on automating perspective drawing analysis, which he published in the 1986 MIT Press Machine Interpretation of Line Drawings. When he asked his computer system to interpret impossible objects, such as in Escher’s paintings, he found that they could be interpreted as drawings of real objects of unexpected shapes.
