Authors: Dolgovesov, B.S. (bsd@iae.nsk.su ) - Institute of Automation and Electrometry, Siberian Branch, Russian Academy of Sciences, Synthesizing Visualization Systems Laboratory (Head of the Laboratory), Ph.D; Vyatkin, S.I. (sivser@mail.ru) - Institute of Automation and Electrometry, Siberian Branch, Russian Academy of Sciences, Synthesizing Visualization Systems Laboratory (Senior Researcher), Ph.D;
Abstract: Transformations of a geometric objects are described for set-theoretic operations, projections, offsetting, and metamorphosis. A binary relation such as collision detection is also described. This approach supports combinations of representational styles, including constructive geometry, sweeping, twisting, deformable and other animated objects. Interactive modification of the function model with fast visualization lets us provide both the interactivity and any required level of detail leading to photo-realistic appearance of the resulting shapes.
Keywords: relations, geometric operations, geometric objects, interactive geometric modeling

38. Reconstruction of images via variational principle [№4 за 2009 год]
Authors: (sachkov@sys.botik.ru) - ; (sachkov@sys.botik.ru) - , Ph.D; (sachkov@sys.botik.ru) - ; (sachkov@sys.botik.ru) - ;
Abstract: A mathematical approach to reconstruction of images via the following variational principle is described: the reconstruction curve (x(t), y(t)) should minimize length in the space (x, y, ), where  is the angle of slope of the curve. A software in Mathematica system for solving the problem is developed, its output is presented. A parallel algorithm for reconstruction of hidden image via the variational approach is proposed.
