The paper briefly reviews the codes and methods resulting from many years of experience in the calculation of nonstationary radiant energy transfer using the visibility coefficients. The visibility coefficients determine the geometrical transfer factors; their direct use in the computational schemes allows to increase the description accuracy of the angular distribution of the radiation energy, to account for the solution smoothness discontinuities and derivatives. The capability for solving the problems in complex shape regions can make useful the conversion variants of codes in engineering and research computations in the fields such as development of infrared and neutron emitters, optimization of radiant heating and energy transfer in outer space, computer graphics. Actually there is an increased interest to the use of the visibility coefficients and authors believe it will further increase in view of the evolution of nanosecond technologies.
