Abstract in different language: One of the main issues in the research on Multi-user Distributed Virtual Reality Systems is the virtual environment description language. A number of different languages with various level of description formalism already exist. In this paper we provide a quick overview of the existing systems. We look more into details of Virtual Reality Modeling Language based on SGI´s Open Inventor format. The problems of multi-user reality systems are farther examined from the point of view of keeping the world database consistent. We present methods reducing the communication demands based on using more complex specification of the environment behavior and distribution of the world database. Finally, the paper provides an explanation of our research. We attempt to design an algorithm for direct global visibility preprocessing, which is an important issue related to the world database subdivision.
