The system including a memory and a processor configured to execute a rendering software application to shoot a plurality of rays through a scene that includes a plurality of lights, generate a plurality of cache points at different locations throughout the scene based on the shooting of the plurality of rays, compute a list of lights for each cache point from the plurality of cache points, the list of lights including lights from the plurality of lights that provide illumination at a location of the cache point, and store the plurality of cache points in a memory. The processor may further be configured to execute the rendering software application to render the scene using the cache point database."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distribution caching for direct lights","description":"There is provided a system and method of distribution caching for direct lights in a scene.
