Global Illumination

Effects

The global illumination section is a permanent part of this series of books, under-

lining the importance of realistic shading techniques and, more specifically, global

illumination effects in real-time applications. The section contains three articles

addressing very different phenomena, each using dedicated data structures and

algorithms in order to achieve the desired performance. The techniques range

from screen-space approximations to using splat-based representations and spa-

tial index structures.

The first chapter in this section is “Ray-Traced Approximate Reflections Us-

ing a Grid of Oriented Splats,” by Holger Gruen. ...
