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. %K computer graphics %K virtual CAVE %K multi-screen mirrors %U http://electroinf.uoradea.ro/reviste%20CSCS/documente/JCSCS_2009/Articole_pdf_JCSCS_C_nr_1/JCSCS_2009_Nr_1_CS_Sobota_Some.pdf
