Abstract

Global illumination is necessary to achieve realistic images. Although there are plenty methods that focus on solving this problem, most of them are not fast enough for interactive environments. Instant radiosity is a method that approximates the indirect lighting, as part of global illumination, by creating additional light sources. Thereby it is very fast and does not need lot of preprocessing, so it is perfectly fit to be used within real-time requirements. Further techniques based on instant radiosity have extended the method to provide better image quality or faster rendering. So instant radiosity and its derivations can bring us global illumination in real-time.
