8/7/2023 0 Comments Dead space 2 stalker chapter 9Reduced CPU usage was one of the main reasons we chose deferred shading in S.T.A.L.K.E.R. Ask a representative of your favorite IHV, who will say that many games are still CPU-limited. One additional crucial fact is usually missed: the ability to cut down on large numbers of batches, which are inevitable when dynamic shadows come into the game. When most people first think about deferred shading, they envision nice algorithmic properties such as perfect depth complexity for lighting, predictable performance proportional to the lights' screen-space areas, simplified scene management, and more. Later we apply lighting as a 2D post-process using this intermediate buffer-usually called a G-buffer (Saito and Takahashi 1990)-as input to the lighting shader. With deferred shading, during scene-geometry rendering, we don't have to bother with any lighting instead, we just output lighting properties such as the position and normal of each pixel. 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. 9.1 Introductionįor those who are not familiar with the concepts of deferred shading, we recommend Hargreaves and Harris 2004. ![]() Because no single solution can suit all needs, this chapter should not be considered a comprehensive guide to performing deferred shading. 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.
