Approximate Reflectance Profiles for Efficient Subsurface Scattering Per H. Christensen, Brent Burley July 2015 We present three useful parameterizations of a BSSRDF model based on empirical reflectance profiles. The model is very simple, but with the appropriate parameterization it matches brute-force Monte Carlo references better than state-of-the-art physically-based models (quantized diffusion and photon beam diffusion) for many common materials. Each reflectance profile is a sum of ... more Paper (PDF) Additional materials: [SIGGRAPH_Tech_Talk.pdf], [approxbssrdfslides.pdf] Available as Pixar Technical Memo #15-04 |
