SUGIHARA Kokichi. Professor, Dr. of Engineering (to my Japanese homepage). My illusion ” Ambiguous Garage Roof”. The roof of a garage and its mirror image . Taken from a Japanese toy set inspired by Sugihara’s mathematical explorations, it looks to be a optical illusion arrow kokichi sugihara x. Kokichi Sugihara is a Japanese mathematician, professor, and artist who specializes in 3D printing “impossible objects” to create.

Sugihara, a mathematical engineer at Meiji University in Japan, has published several studies based off his creations and he’s also twice won the award for Best Illusion of the Year.

The mathematical structure of this tiling pattern is the same as Escher’s artwork, “Sky and Water I” He won first prize in the Best Illusion of the Year contest twice.

Kokichi Sugihara – Wikipedia

Professor of Mathematical Engineering. He creates mind-bending physical objects that look and behave in incredible ways when seen from the right angle, such as marbles that roll uphill or circular pipes that look rectangular in a mirror. One of his research areas is computational approaches to visual illusions.

He then became an associate professor in the Department of Information and Computer Engineering at Nagoya University inand moved back to the Department of Mathematical Engineering and Information Physics at the University of Tokyo in With three co-authors, he wrote Spatial Tessellations: Sugihara creates his objects as part of his academic research.

I gave the top bee and the bottom stag beetle to my computer program, and the program generated the intermediate tiles and their placements.


From Wikipedia, the free encyclopedia. Escherhe discovered that they could be interpreted as drawings koklchi real objects with unexpected shapes. The red square ring passes behind the vertical column, but at the same time passes in front of all the four horizontal perches; thus it generates the illusion of an impossible object.

The two penetrating plates align horizontally at the left but vertically at the right, giving the impression of an impossible object. These objects may be mind-boggling, but they are not difficult to craft. Kokichi Sugihara’s ‘impossible’ objects. Some of Sugihara’s illusions are meant to be seen in motion.

Yet the illusions are so powerful that some have questioned their authenticity: In this sense, this illusion is strong and robust,” he said. This is your brain on tidiness: Eccentric Ring Toss 2.

I introduced a mathematical approach to this topic, and thus can create new types of 3D optical illusions,” he explained in an email interview. One such example, a winner of Best Illusion of the Year, is called “Magnet-like slopes.

StoyanBiometrical Journal 36 2: Perhaps the most astonishing of his impossible objects is a simple white arrow pointing to the right. But not with this one, Sugihara notes: Only when it is sugihaga the eye correctly interprets the size of the central pillar, which is shorter than it seems.

Most of the illusion comes from the edges: The shape is affected by the viewing angle.

From to he worked as a researcher at the Ministry of International Trade and Industry. The psychology of ‘organization porn’. Unlike traditional optical illusions, which short-circuit our brain’s visual processing system, Sugihara’s kikichi involve no visual trickery other than perspective. Turner Broadcasting System, Inc. Sugihara’s research also includes the study of Voronoi diagrams.


His illusion “Ambiguous cylinder” has the professor moving a series of objects, which he has 3D printed, in front of a mirror.

Master of illusion: Kokichi Sugihara’s ‘impossible’ objects

The secret is in the shape of the object, which is only revealed fully when the viewing angle is modified. When we see it with one eye from the specific viewpoint, we perceive an object consisting of a sugiuara column and four perches extending horizontally by mutually right angles.

Sugihara’s ambiguous objects are a mathematical work of art that sugihra the physics of optics to show us how our senses and perceptions can be fooled, and yet we can fully understand how the phenomena works,” said in an email Ray Halla professor of physics at California State University, who made the skgihara above using a Japanese toy set which includes objects derived from Sugihara’s studies.

Concepts and Applications of Voronoi Diagrams Wiley, ; 2nd ed. This is a solid that generates the visual impression of an impossible object when it is seen from a specific viewpoint.


I also feel that mathematics has the power to create what has never existed. The marbles roll uphill! A mathematician is using computers to manufacture award-winning illusions”Nautilis.
