The effect of user “immersion” into virtual reality in such systems is largely dependent on optical properties of the system. In this paper, problems of luminance distribution uniformity in CAVE-type virtual reality systems are analyzed. For better characterization of CAVE luminance nonuniformity corner and edge CAVE nonuniformity were introduced. Based on described CAVE-type virtual reality laboratory, named Immersive 3D Visualization Lab (I3DVL) just opened at the Gdansk University of Technology, luminance nonuniformity of the system is evaluated and discussed. Data collection of luminance distribution allows for software compensation of intensity distribution of individual images projected onto the screen (luminance non-uniformity minimization) in the further research.}, type={Article}, title={Analysis of luminance distribution uniformity in CAVE-type virtual reality systems}, URL={http://journals.pan.pl/Content/115301/PDF/main.pdf}, keywords={Virtual reality, CAVE, Scattering distribution function, Luminance distribution, Uniformity measurement}, }
