  • Revision 2020: Physically Based Shading Without Locking Yourself In
    ★ 1 0
    Implementing a physically based shading model without locking yourself in
  • Advanced Global Illumination Using Photon Mapping
    ★ 0 0
    Photon mapping provides a practical way of efficiently simulating global illumination including interreflections, caustics, color bleeding, participating media and subsurface scattering in scenes with complicated geometry and advanced material models. This class will provide the insight necessary to efficiently implement and use photon mapping to simulate global illumination in complex scenes. The presentation will briefly cover the fundamentals of photon mapping including efficient techniques and datastructures for managing large numbers of rays and photons. In addition, we will describe how to integrate the information from the photon maps in shading algorithms to render global illumination.
  • Matrix row-column sampling for the many-light problem
    ★ 0 0
    Computing global illumination using the many-lights approach is expensive, this algorithm presents a method ("exploration") for reducing the amount of lights to be sampled.
