论文摘要
虚拟现实系统为科学研究和消费者享受提供了许多机会；但是，它们比传统的桌面应用程序要求更高，并且需要与台式机的有线连接以享受最高质量。存在与计算机未连接的独立选项，但它们由移动GPU提供动力，与桌面渲染相比，它提供了有限的功率。提高移动设备性能的替代方法使用服务器渲染为客户端渲染帧，并主要将客户端视为显示设备。但是，当前的流媒体解决方案在很大程度上遭受了由于处理和网络要求以及客户未充分利用而导致的高端到端延迟。我们提出了一种联网的分割方法，以在保留图像质量的同时，在移动设备上实现更快的端到端图像呈现率。我们提出的解决方案在服务器端GPU和移动客户端之间使用了图像空间划分，并且比仅限客户端渲染的运行时要快得多，而不是使用薄级别的方法，该方法主要依赖于服务器。
Virtual Reality systems provide many opportunities for scientific research and consumer enjoyment; however, they are more demanding than traditional desktop applications and require a wired connection to desktops in order to enjoy maximum quality. Standalone options that are not connected to computers exist, yet they are powered by mobile GPUs, which provide limited power in comparison to desktop rendering. Alternative approaches to improve performance on mobile devices use server rendering to render frames for a client and treat the client largely as a display device. However, current streaming solutions largely suffer from high end-to-end latency due to processing and networking requirements, as well as underutilization of the client. We propose a networked split-rendering approach to achieve faster end-to-end image presentation rates on the mobile device while preserving image quality. Our proposed solution uses an image-space division of labour between the server-side GPU and the mobile client, and achieves a significantly faster runtime than client-only rendering and than using a thin-client approach, which is mostly reliant on the server.
