Garbaruk I. Geometrical modeling of natural illumination from specularly reflecting light wells

The thesis for the Candidate's Degree in engineering science at speciality 05.01.01 - Applied geometry, engineering graphics. - Kiev national university of con-struction and architecture, Kiev, 2016. The dissertation is devoted to geometrical modeling the efficiency of light wells and wells in the form of a parallelepiped with a specular reflection of light, and modeling of illumination from cylindrical light wells and wells in the form of a parallelepiped with a specular reflection of light for cloudy model of a firmament. A geometrical way of modeling of efficiency of wells in the form of a parallelepiped is developed and improved a geometrical way of modeling of efficiency of cylindrical light wells concerning visualization of dependence of the efficiency created by the reflected light from an index of well and the analysis of nature of change of curve illumination along diameter of well. Graphs of dependence of efficiency of light well on its index are constructed. Developed a way for definition of rational proportions of light wells with a diffusion and specular reflection of light that allows to picking up such wells in which the part of an initial light stream, created by light reflected from walls of well, is the greatest. Comparison of efficiency of light wells of identical and different forms executed. Developed a way of modeling of illumination and a light vector for cylindrical light wells and wells in the form of a parallelepiped with a specular reflection of light, concerning development of the corresponding software. Visualized the surfaces of illumination, projections of a light vector and light field under the shaft that allowed estimating illumination under light well.
