The Develop Conference will be taking place between July 24th to the 26th in Brighton, UK. Even though this event will be taking place after E3, we’ll get a chance to hear about some of the development techniques behind Killzone for the PS3.
Deferred rendering in Killzone 2
Michal Valient, Guerrilla-Games
Next generation gaming brought high resolutions, very complex environments and large textures to our living rooms. With virtually every asset being inflated, it’s hard to use traditional forward rendering and hope for rich, dynamic environments with extensive dynamic lighting. Deferred rendering, on the other hand, has been traditionally described as a nice technique for rendering of scenes with many dynamic lights, that unfortunately suffers from fill-rate problems and lack of anti-aliasing and very few games that use it were published.
In this talk, we will discuss our approach to face this challenge and how we designed a deferred rendering engine that uses multi-sampled anti-aliasing (MSAA). We will give in-depth deion of each individual stage of our real-time rendering pipeline and the main ingredients of our lighting, post-processing and data management. We’ll show how we utilize PS3’s SPUs for fast rendering of a large set of primitives, parallel processing of geometry and computation of indirect lighting. We will also describe our optimizations of the lighting and our parallel split (cascaded) shadow map algorithm for faster and stable MSAA output.
Take Away
The session will provide detailed overview and optimizations of modern rendering engine and parallel processing. Many of the topics are applicable for various gaming platforms.
据技术人士透露，KZ2应用的技术至少需要G80或者R600才能实现，目前有两种可能：1、RSX具备某些G80特性。
2、CELL可以模拟DX10，而且效率不错。. |
