Techniques are disclosed for rendering graphics objects in a scene file. A first pixel is selected from a plurality of pixels that are associated with an image frame. A set of graphics objects that intersect with the first pixel is identified. For each graphics objects in the first set of graphics objects. a set of light sources that illuminates the respective graphics object at the first pixel is identified, and, for each light source in the set of light sources, an entry is stored in a first table that includes references to the first pixel, the respective graphics object, and the respective light source.
