Abstract:
Digital relighting of a scene is achieved by recording images of the scene under varying lighting conditions, and then recombining these to simulate the scene under new lighting configurations which may have never existed previously. Though simple in principle, and computationally efficient, the main obstacle to its application is the requirement for full control of the lighting environment to create the initial scene data. Such control is available in theatrical environments where stage lighting is controlled from a central lighting desk. High end lighting systems may include a PC within the lighting system which can provide 3D rendered previews of the on-stage lighting, but these require the user to model the stage, and the visual quality of these previews is poor. Stage lighting may be highly dependent on participating media, caustics, color bleeding, UV and other effects which are challenging to render and cannot be generated in real time. However these effects can easily be supported by digital relighting.
