The algorithm is divided into two passes, namely a shadow pass and a lighting pass. The shadow pass renders the scene using stochastic rasterization and generates a time-dependent shadow map augmented with per-sample motion vectors. The subsequent lighting pass renders the scene from the camera's point of view, and performs a shadow query for each sample seen from the camera."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Filtered shadow mapping","description":"A layered, filtered shadow mapping algorithm may be used for motion blurred shadows.
