According to embodiments of the invention, secondary rays may be pooled after they are generated by a vector throughput engine. After pooling the secondary rays, they may be reordered according to similarities in trajectory and originating location.

The reordering of the secondary rays may cause rays which traverse similar portions of the spatial index to be traversed immediately following (or shortly thereafter) one another. Consequently, the necessary portions of the spatial index may remain within the workload manager's memory cache, thereby reducing the number of cache misses and the amount of time necessary to traverse secondary rays through the spatial index. The reduction in time necessary to traverse the secondary rays through the spatial index may improve the overall performance of the image processing system. |
