This paper introduces a new approach to the problem of direct illumination in physically-based rendering of 3D scenes using illumination maps captured from real environments. We developed a system that takes advantage of the best features of the current solutions to the problem: namely, the approximation of illumination maps through directional lights; and stochastic sampling of the light maps. Our framework is flexible and can be used with most rendering programs.
