Differential geometty and topology are the areas of higher mathematics, which particularly require visual representation of studying objects for better understanding of the material. On the other hand, the complex structure of such objects niakes their visualization a challenge for modern graphical systems. In this paper we describe some methods useful for adequate representation of topologically non-trivial objects in virtual environment systems, particularly the acceleration of standard mechanisms for rendering of transparent surjiaces, applicable for complex cases of self-intersecting time-dependent surjaces, not necessarily admitting continuous jields of normal vectors. We also use a simple technique of image-based rendering, which places stereo-photographs of real environments as static background for 3 0 virtual scenes. The methods are iniplemented in educational application, which demonstrates the ntain properties of elementary topological objects (Moebius band, Klein bottle, projective plane etc) and gives a possihiliq to explore interactively the complex constructions, arising in higher mathematics.

We develop mdtimedia technology for enriching the music fitening eqerience. We propose a system-MdiSpace -in which mers may kten to music \vMe controtig in rd tie the lo-ation of sound sourcw, through a simple interface. We introduce the problem of mtiiizg co~zsfite~zcy, and propose a solution based on a constraint propagation mechbm.The proposed system contains both m authoring mode, in which sound engineers may specify spati*ation constraints to be satisfied, and a fitening mode in which kteners m modify the Io&tion of sources under the Supetilon of a constraint solver that ensures the spati~ation always satisfies the constraints. We describe the architecture of the system =d report on e~eriments done so far.
