Research Description
Geometric images are probably the eldest product of the human brain. In the 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 a computer.
We try to find an approach dealing with geometric objects in the most
simple and
uniform manner. Thus, the Function Representation (FRep) of geometric objects
has been
introduced with set-theoretic operations based on the theory of
R-functions
developed by Russian mathematicians. This representation is independent
of
the space dimension.
That is why time-variant or animated objects can be described in the
same way, with time being considered as one of the coordinates of space-time.
Many unusual geometric operations such as blending, metamorphosis and even
"hair growing"
can be functionally described. 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. This becomes even more
complex when dealing with heterogeneous volumetric objects and multidimensional models. Combining rigorous mathematical models with powerful parallel computers, we will get an instrument
for the future creative work in design, medicine and biology, industry and art.
FRep Home Page presents descriptions of
selected research topics, list of publications, images, and animations.
HyperFun project
provides tools for FRep modeling using the HyperFun language.
