The Fundamental Topics of Static Global Illumination Algorithms for 3D Games

Global Illumination is a challenging topic in 3D game. Several algorithms have been developed using various approaches. The first algorithm is developed using geometrical approach. Nowadays, the development is shifted to texture based and physics based approach. In proposing the algorithm, the developer also has a different focus. Some of them are optimizing memory usage, some of them are improving visual appearance. To keep up with the development of Global Illumination, academician have to understand about state of the art and fundamental concept underlying Global Illumination. Based on the ambience that is handled, we could classify Global Illumination algorithm into two types. They are static global illumination that handle single ambience color and dynamic global illumination that handle complex indirect illumination with more than one ambience colors. In this paper, we summarize some algorithm in static global illumination. The aim of this paper is defining fundamental concept underlying static Global Illumination in order to minimizing gap between industries and academician.
