Originální abstrakt

This article describes the influence of directional reflectance for the lighting calculations. Also compares the difference between the calculations of materials ideally diffuse and real materials. For real material applies that indicatrix of reflected light and reflecting material are not behaving as an omni directional diffusor, but under certain angles are starting to behave almost like a mirror. This contributes to an erroneous calculation of lighting, because the existing computer programs allow for real reflective materials as ideal. This error has resulted in unnecessary over-lighting certain places, and ultimately a waste of electricity.
