Abstract: The Decima engine was originally developed for the Killzone series, and is now powering Horizon: Zero Dawn as well as Death Stranding (Kojima Productions). In this talk we’ll cover some of the rendering techniques we developed for these titles. Topics include an improved method for approximating spherical area lights by bending the light vector of a single point light, practical realistic atmospheric scattering with height fog, our 2-frame temporal anti-aliasing solution for 1080p, and finally our optimized 2160p checkerboard rendering and ‘tangram’ resolve strategy used on the PS4 Pro.
