Abstract: This report presents an extensive empirical comparison of matrix, progressive, and wavelet radiosity algorithms for simulating diffuse interreflection in three-dimensional scenes. The algorithms are tested in their basic forms, without advanced variations such as clustering, discontinuity meshing, or Monte Carlo techniques. The three algorithms were implemented in a common code base to facilitate direct empirical comparison. A number of parameterized scenes were designed to test the basic... (Update)
