    • An Efficient Transport Estimator for Complex Layered Materials 

      Gamboa, Luis E.; Gruson, Adrien; Nowrouzezahrai, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Layered materials capture subtle, realistic reflection behaviors that traditional single-layer models lack. Much of this is due to the complex subsurface light transport at the interfaces of - and in the media between - ...
