ARCHITECTURE UNIFIÉE POUR LA CONSTRUCTION DE BVH BASÉE SUR UN PRÉ-TRI DE MATÉRIEL ET UN RÉSEAU DE REGROUPEMENT PARALLÈLE ET RECONFIGURABLE

摘要

An apparatus comprising a sorting unit to sort primitives of a graphics image, the primitives to be grouped, each group to form a first level node of a hierarchical acceleration structure; a parallel reconfigurable clustering array to construct the hierarchical acceleration structure, the parallel reconfigurable clustering array comprising a plurality of processing clusters, each cluster comprising: parallel efficiency analysis circuitry to evaluate different groupings of the first level nodes for a next level of the hierarchical acceleration structure to determine efficiency values for the different groupings; and node merge circuitry to merge the first level nodes based on the efficiency values to form second level nodes.
