The Hemisphere Radiosity Method: A Tale of Two Algorithms
The most important and most computationally-intensive operation within the radiosity illumination model is the calculation of form-factors, the geometric measure of the fraction of the radiant energy leaving one surface and received by another surface. This form-factor calculation must account for potential obstructions between the target surfaces yet be computationally efficient and accurate.
