New method for rendering impossible figures

Hong Kong specialist Tai-Pang Wu has developed the most realistic method for rendering impossible figures to date. Perhaps someday in the virtual space of computer games it will be possible to render the stairs in Escher style, and they will look realistic from any angle, as well as with different lighting. An impossible ladder will even roll a ball under the force of gravity.

By the way, in the game Diablo II there was one impossible object, but it can only be viewed from a single angle.

Everyone likes optical illusions, and to consider them is an excellent exercise for spatial thinking, but, according to experts, it will be difficult to find a commercial application of this technology.

Since impossible figures can not exist in three-dimensional space, for rendering use several special techniques. As a result of this, according to the developer, the object “as if an ameba” smoothly flows from one state to another.

The results of “Modeling and Rendering of Impossible Figures” were published in ACM Transactions on Graphics (ToG), vol. 29, No. 2, Article 13, March 2010. The text of the article can be downloaded in pdf , and the demo video is packed in zip .
