The some problems solution by construction of multi-screen projection system

The paper describes the some problems by construction of CAVE projection system. This system is a part of the virtual reality system PROLAND developed on the Department of Computers and Informatics FEI TU Ko ice. In first part are described some possibilities of multi-projection systems (including CAVE system). The main part indicates some construction problems of cave system: size and projectors number. Afterwards is described a problem of mirror’s adjustment. These mirrors are used by this cave and they are used to decrease of projectors number.
