Large-Scale Global Illumination in Call of Duty

Ari Silvennoinen

In this talk, we describe the key techniques behind the large-scale global illumination system in Call of Duty. We present a new precomputed lighting compression technique that enables high-performance and seamless reconstruction directly from the compressed lighting data. In addition, we discuss visibility-based sampling of precomputed volumetric lighting and describe a practical method for computing constrained spherical harmonics representations.
