Abstract

When compositing computer generated imagery into photographed scenes, image based lighting (IBL) [Debevec 1998] is used so that synthetic and real objects are consistently illuminated. Traditional IBL takes light captured from a single point in space however light varies spatially in many scenes. Unger et al. [2003] captured a light field for lighting, but the acquisition procedures were not practical for typical scenes. I present a practical IBL method for rendering scenes with spatially variant light.
