Realistic image synthesis requires both complex and realistic models of real-world light sources efficient rendering algorithms to deal with them. In this paper, we describe a processing pipeline for dealing from acquisition global illumination rendering. We carefully design optical filters guarantee high precision measurements sources. discuss two practically feasible setups that allow us measure different characteristics. Finally, introduce an importance sampling algorithm our representation can be used, example, in conjunction Photon Maps.
