A Multi-Faceted Exploration (Part 1)


As part of the Physically Based Shading Course at SIGGRAPH last year, Christopher Kulla and Alejandro Conty presented the latest iteration of Sony Pictures Imageworks’ core production shading models. One area of focus for them was to improve the energy conservation of their materials; in particular they wanted to compensate for the inherent lack of multiple scattering in common analytic BSDFs, which can be a major source of energy loss. (More on this later.)
