This presentation reviewed subsurface scattering theory and algorithms. The main algorithmic focus was on analytic BRDF models [1, 7], Monte Carlo evaluation techniques [4, 16], and diffusion approximations for multiple scattering [11, 9, 3, 14]. Other references I read or skimmed are also listed below. Areas I didn't get to in class are approximations for meshes [8, 13, 15], nonhomogeneity modeling [2, 19], the measurement of objects or model parameters [11, 5, 2, 19], applications of the Kubelka-Munk model[6], and models designed for biophysical accuracy [12]. Particular papers I left out for sake off time were the wet surface paper [10] and Jos's analytic model for skin layers with rough boundaries [18]. It's also worth looking at Jos's paper that introduced the idea of using diffusion for multiple scattering [17].
