Simulation of partially obscured scenes using the radiosity method
Christoph C. Borel, Siegfried A. W. Gerstl · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1991
The extended radiosity method or zonal method is used to construct realistic synthetic images (in the visible and IR) containing radiatively participating media such as smoke, fog, and clouds. Computational methods are discussed as well as the rendering of various scenes using computer graphics methods. The extended radiosity equations and an efficient algorithm to compute the radiosties and radiances in a homogeneous participating medium over an inhomogeneous flat surface are presented.
