摘要： At least one processor may organize a plurality of primitives in a hierarchical data structure. The at least one processor may rasterize a plurality of bounding volumes associated with non-root nodes of the hierarchical data structure to an off-screen render target. The at least one processor may determine a bounding volume that is intersected by a ray out of the plurality of bounding volumes. The at least one processor may determine a non-root node of the hierarchical data structure that is associated with the bounding volume as a start node in the hierarchical data structure to start traversal of the hierarchical data structure. The at least one processor may traverse the hierarchical data structure starting from the start node to determine the primitive that is intersected by the ray.

摘要翻译： 至少一个处理器可以在分层数据结构中组织多个基元。 所述至少一个处理器可以将与分层数据结构的非根节点相关联的多个边界卷光栅化到离屏渲染目标。 所述至少一个处理器可以确定由所述多个边界卷中的射线相交的边界体积。 所述至少一个处理器可以将与所述边界卷相关联的所述分层数据结构的非根节点确定为所述分层数据结构中的起始节点以开始遍历所述分层数据结构。 至少一个处理器可以从起始节点开始遍历分层数据结构，以确定与射线相交的原语。
