Abstract : Physically based rendering with global illumination effects, has become a standard technique for high quality computer generated imagery. Nonetheless, being able to control and edit the resulting picture so that it corresponds to the artist vision is still a tedious trial and error process. We introduce a path selection and edition metaphor, to give the artist a precise control over the final rendering without modifying the scene parameters. Starting from the identification of a lighting feature and its transcription in a path space regular expression, the proposed approachconsists in selecting the corresponding light transport paths in 3D space and transforms them according to user defined operations. We demonstrate the wide range of control it permits on various lighting features, from low frequency color bleeding to high frequency caustics as well as view-dependent reflections.
