摘要： In an example, ray tracing scenes includes using a plurality of intersection testing resources coupled with a plurality of shading resources, communicative in the aggregate through links/queues. A queue from testing to shading comprises respective ray/primitive intersection indications, comprising ray identifiers. A shading to testing queue comprises identifiers of new rays for test, wherein data defining the rays is separately stored in memories distributed among the intersection testing resources. Ray definition data can be retained in distributed memories until rays complete intersection testing, being selectable for testing multiple times based on ray identifier. A structure of acceleration shapes can be used. Packets of ray identifiers and shape data can circulate among intersection testing resources, each resource can test rays identified in the packet, and for which definition data is present in its memory. Acceleration shape test results allow collection of rays based on intersected shape, and closest detection ray/primitive intersections are indicated by queuing ray identifiers for shading.
摘要翻译：在一个示例中，光线跟踪场景包括使用与多个着色资源相耦合的多个交叉点测试资源，通过链路/队列在聚合中通信。从测试到阴影的队列包括相应的射线/原始相交指示，包括射线标识符。对测试队列的阴影包括用于测试的新射线的标识符，其中定义射线的数据被分别存储在分布在交叉点测试资源之间的存储器中。光线定义数据可以保留在分布式存储器中，直到光线完成相交测试，可以根据光线标识符多次选择进行测试。可以使用加速形状的结构。光线标识符和形状数据的包可以在交叉点测试资源之间循环，每个资源可以测试在分组中标识的光线，并且其存储器中存在定义数据。加速度形状测试结果允许基于相交形状收集射线，并且通过排列用于阴影的射线标识符来指示最接近的检测射线/原始交点。
