The subject of the study is how to determine the angular coefficients of radiation (AСR) in the tasks of forming families of lines - contours of the geometric models of burnout. The aim is the empowerment of the geometric modelling of objects of energy radiation in the problems of forming their boundaries. Methods: of applied geometry, numerical methods, mathematical apparatus R functions, elements of computer graphics in media processor Maple. Theoretical and practical results: improved method of determining the projection of local AСR for figures not located at the coordinate planes, has been developed method of determining the integral of the USP for any part of the plane; compiled programs, which allow showing the histograms of distribution of local AСR on the plane. Areas of use: theoretical results are due to applied geometry, practical results can be applied in fire safety.
