Radiative Transfer Networks Revisited

摘要

The radiosity equation is used in computer graphics for photorealistic image synthesis, and in thermal and illumination engineering for radiative and luminous flux transfer calculations. Because it may involve extremely large matrices, considerable efforts have been devoted to finding fast iterative solution methods that do not con- sume large amounts of memory. In the 1950s, thermal and illumination engineering researchers noted that the net flow of infrared and visible light between surfaces is analogous to the flow of electri- cal current in linear resistive networks. This analogy was investigated in depth, but it unfortunately did not lead to useful techniques for solving the radiosity equation.
