DescriptionSpherical Gaussian (SG) lighting is an efficient approximation for real-time rendering. To improve the quality of SG lighting for diffuse surfaces, we present a more accurate approximation than previous methods for the irradiance from SG lights. Our approximation is simple, easy to implement, and less expensive than the state-of-the-art method.
