FOREWORD

The Quest for Realism has motivated much of the history of rendering, the process of creating synthetic imagery with computer graphics. The earliest work in this area concerned the development of plausible local illumination models, the study of how light reflects off a surface. Later work concerned the problem of solving for the equilibrium solution of light reaching all surfaces as the light reflects about an environment, a problem known as global illumination. The careful characterization of these problems as physical processes that can be simulated with ever-increasing speed and accuracy ...
