    Advanced Global Illumination Using Photon Mapping



    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. A large portion of the class will be dedicated to advanced techniques for photon mapping. In addition to a fast recap of introductory material, we will describe more recent developments including efficient methods for using photon mapping in scene with participating media and subsurface scattering.
