摘要： The effective illumination volume (e.g., angular spread and falloff) of each light source in an object model scene can be represented by a simple geometry. Geometry-based culling techniques then can be used to automatically remove or de-activate lights for a frame, set of frames, or entire shot of animation, based on interactions of the light geometries with objects in the scene. The light pruning process can be run in a pre-pass procedure, such that production and rendering preparation procedures do not have to deal with lights that will not affect the final image. Further, a pre-pass pruning removes lights before rendering, such that the data for each light does not have to be loaded into memory at render time. Removing the lights before rendering also can reduce the amount of ray tracing and other processing used for the lights at render time.

摘要： Programmable or user-defined visibility functions can be defined to achieve rendering effects and eliminate rendering errors. A renderer traverses the set of geometry samples potentially visible to an image sample. Rather than accumulate opacity and color in strict depth order, the renderer can invoke visibility functions associated with some or all of the geometry samples. Each geometry sample's visibility function can access attributes of any other geometry sample associated with the image sample. Furthermore, each geometry sample's visibility function can identify the position of its associated geometry sample and any other geometry samples in the depth sequence of geometry samples associated with an image sample. A visibility function can return any arbitrary value based on attributes of its associated geometry sample, attributes of other geometry samples associated with the image sample, and/or the position of geometry samples in the depth sequence associated with the image sample.
