Ha, H: Automatic Lighting in Computer Graphics

A significant problem in the automatic of 3D graphics is the configuration of the lighting for a scene. The number of lights included, and the properties of these lights, has an enormous impact on what a viewer can judge about the content, properties and other aesthetic qualities of a scene. Non-expert users encounter a number of difficulties in selecting the appropriate lighting parameters, as the process requires both a subtle technical and aesthetic understanding of lighting in computer graphics. In this book, an intuitive approach to lighting , lighting-by-example, is proposed and extensively explored in forms that exploit both the perception-based lighting framework and a new wavelet formulation. User studies are conducted both to configure the perception-based lighting objective function and to evaluate the performance of the proposed lighting approaches. Finally, an approach to ing interactive interface for the lighting process that incorporates both the ideal lighting and lighting-by-example approaches is presented.
