Abstract
This report describes an application of real-time photon mapping to enhance realism of lighting and to automate illumination work in interactive applications. The rst part of this report reviews the essential theory about light and real-time photon mapping whereas the second part discusses the implementation and results in detail. Two major problems of real-time photon mapping are discussed: performance and visual quality. The main con- ict is between image quality and real-time constraints. The key to improve quality is to increase photon and polygon count of the scene. However, increasing either of these decreases performance. The conclusion outlines a method to obtain a good image quality in real-time and describes problems that are subject to future work.
