For the next STORM seminar, Mathias Paulin will give a presentation titled : Position-free Multiple-bounce Computations for Smith Microfacet BSDFs – Reading and discussion
Abstract: Bidirectional Scattering Distribution Functions (BSDFs) encode how a material reflects or transmits the incoming light. The most commonly used model is the microfacet BSDF. It computes the material response from the microgeometry of the surface assuming a single bounce on specular microfacets. The original model ignores multiple bounces on the microgeometry, resulting in an energy loss, especially for rough materials. This paper presents a new method to compute the multiple bounces inside the microgeometry, eliminating this energy loss.
