论文摘要
我们以数据分配方式进行完整的路径跟踪渲染生产风格的内容的概念 - 也就是说，每个存储都只有多个合作的节点和/或GPU，而每个存储只有模型的一部分。特别是，我们提出了一种新的方法来追踪不同节点/GPU的射线，以改进传统的空间分区，可以支持对象空间和空间分区（或任何组合），并启用多种技术来减少整个网络中发送的射线数量。我们表明，这种方法可以处理不同种类的模型分区策略，并且最终也可以通过完整的路径跟踪呈现非平凡的模型，即使在具有相当低端互连的相当温和的硬件资源上也是如此。
We investigate the concept of rendering production-style content with full path tracing in a data-distributed fashion -- that is, with multiple collaborating nodes and/or GPUs that each store only part of the model. In particular, we propose a new approach to tracing rays across different nodes/GPUs that improves over traditional spatial partitioning, can support both object-space and spatial partitioning (or any combination thereof), and that enables multiple techniques for reducing the number of rays sent across the network. We show that this approach can handle different kinds of model partitioning strategies, and can ultimately render non-trivial models with full path tracing even on quite moderate hardware resources with rather low-end interconnect.
