虚拟环境目前被限制在不超过一百个交互用户的模拟器为中心的服务器架构用于许多这些应用程序。有一些潜在的新用途，如虚拟音乐会和体育赛事，涉及数百或数千名用户，我们寻求使这些令人兴奋的新应用程序。我们提出了一个分布式场景图（DSG）的架构，使大规模的扩展场景的复杂性和参与者的硬件。DSG组件管理客户端通信的原型实现表明，并发用户的数量增加了一个数量级。我们提出了这个组件的设计DSG架构，原型实现的基础上，一个开源的虚拟环境服务器和我们的实验设置，工作负载和结果。
Virtual environments are currently limited to no more than a hundred interacting users by the simulator-centric server architectures used for many of these applications. There are some potential new usages such as virtual concerts and sporting events involving hundreds or thousands of users and we seek to enable these exciting new applications. We propose a distributed scene graph (DSG) architecture which enables massive scaling of scene complexity and participants with the addition of hardware. A prototype implementation of the DSG components to manage client communications demonstrates an order of magnitude increase in the number of concurrent users. We present the design of this component within the DSG architecture, prototype implementation based on an open source virtual environment server and our experimental setup, workloads and results.
