Background Data

Professor Pasko came to the University of Aizu from the Moscow Engineering Physics Institute (MEPI). He was a senior scientist at MEPI from 1988 to 1992. He is a member of the Eurographics Association. He received First Prize in the National Competition of Young Specialists in Computer Science in 1984. He was awarded a Diploma of the USSR Academy of Sciences in 1985 and a medal of the National Exhibition Center in 1987. He is now an Assistant Professor in the Shape Modeling Laboratory.

Research/Educational Interests

Research Description

Geometric images are probably the eldest product of the human brain. In modern logically-oriented life it is extremely important to keep and develop this ability. I am convinced that outstanding achievements in science and technology can only be attained in the balance of logic and geometric reasoning.

There are many ways of modeling geometry by means of computer. We try to find an approach dealing with geometric objects in the most simple and uniform style. Thus, function representation (F-rep) of geometric objects has been introduced with set-theoretic operations based on the theory of R-functions recently developed by Russian mathematicians. This representation is independent of the space dimension. That is why time-dependent or animated objects can be described in the same manner, with time being considered as one of the coordinates of space-time. Many unusual geometric operations like blending, metamorphosis and even "hair growing" can be functionally described. Sometimes it seems we now have "experimental geometry" by analogy with experimental physics, where new results usually have to be explained from the theoretical point of view. By using more powerful parallel computers and by adding intellect to artificial actors we will get an instrument for future creative work in art and design, medicine and industry.

F-rep Home Page presents descriptions of selected research topics, list of publications, images, and animation.
HyperFun project provides tools for F-rep modeling using HyperFun language.
