This chapter is a post-mortem of almost two years of research and development on a renderer that is based solely on deferred shading and 100 percent dynamic lighting, targeted at high-end GPUs. Because no single solution can suit all needs, this chapter should not be considered a comprehensive guide to performing deferred shading.

Introduction

For those who are not familiar with the concepts of deferred shading, we recommend Hargreaves and Harris 2004. This presentation is a good introduction to the basics, and it briefly showcases a number of techniques originally developed for and used in the game S.T.A.L.K.E.R. With deferred shading, during scene-geometry rendering, ...
