ILLUMINATION WITH ELECTROCHROMATIC WINDOWS IN VIRTUAL REALITY

Electrochromatic materials are characterized by reversible colour change when placed in an external electric field. One of the possible applications of such electrochromatic films is in the "Smart windows" that are used to modulate the transmitted light in objects. Thin electrochromatic films of copper oxide are obtained by the chemical deposition method of two solutions. The spectral transmission of the resulting films was recorded in a state as obtained, in a coloured and shaded state, in the visible part of the spectrum. From the sum of the intensity of the incident solar spectrum AM 1.5 and the amount of intensity of the spent radiation through the films, the mean values of the transmission coefficient of the films in the three states are determined, in the wave interval from 350 to 820 nm. The obtained results for the mean value of the transmission coefficient are used to simulate the illumination in the virtual reality, to a real object in which the outer illumination is modulated when passing light on the case when the windows would be examined films in the state as the film was obtained, in a coloured and shades condition. The simulation of the process is using Quest3D software for virtual reality.
