发明名称 Methods and systems for reducing the number of rays passed between processing elements in a distributed ray tracing system
摘要 Embodiments of the invention provide techniques and systems for reducing network traffic in relation to ray-tracing a three dimensional scene. According to one embodiment of the invention, as a ray is traversed through a spatial index, a leaf node may be reached. Subsequent rays that traverse through the spatial index may reach the same leaf node. In contrast to sending information defining a ray issued by the workload manager to a vector throughput engine each time a ray reaches a leaf node, the workload manager may determine if a series of rays reach the same leaf node and send information defining the series of rays to the vector throughput engine. Thus, network traffic may be reduced by sending information which defines a series of rays which are traversed to a common (i.e., the same) leaf node in contrast to sending information each time a ray is traversed to a leaf node.
