METHOD AND SYSTEM FOR MODELING LIGHT

摘要

A method and system for modeling light in time and space are provided. The method and system of the present disclosure collect light readings, e.g., on a motion picture set, at different positions and times (302, 304, 306) to build a light model to be used for visual effects (VFX) compositing (308). The light model represents the light distribution across space and/or time for a predetermined physical space. Using the light model, the lighting can then be predicted or interpolated at intermediate or other positions and/or times for which no specific light readings were obtained (314). The light models can be used for rendering objects (e.g., natural or CG elements) in a scene as if they were in that space.
