An approximate reflectance profile for efficient subsurface scattering
Per H. Christensen · 2015
Computer graphics researchers have developed increasingly sophisticated and accurate physically-based subsurface scattering BSSRDF models: from the simple dipole diffusion model [Jensen et al. 2001] to the quantized diffusion [d'Eon and Irving 2011] and beam diffusion [Habel et al. 2013] models. We present a BSSRDF model based on an empirical reflectance profile that is as simple as the dipole but matches brute-force Monte Carlo references better than even beam diffusion.
