It is based on uniform grid of cells, and on local stencils in cells. The acceleration structures are abandoned along with high traversal and construction costs of these structures. The amount of intersection tests is cut down. The stencils are generated in the preprocessing stage and utilized in runtime. The relevant part of scene data, critical for shadowing of all visible intersection points in a cell, is registered in the local stencil map, as a volumetric data. The runtime use of stencils allows a complete locality at each cell, enhanced utilization of processing resources and load balancing of parallel processing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stencil mapped shadowing system","description":"Aspects comprise shadowing system as part of ray tracing.
