一种基于网络的并行渲染和跨平台同步展示系统

摘要

虚拟现实的实时展示和交互的应用越来越广泛,但由于普通PC机渲染的性能问题,无法在保证帧率的条件下渲染超高分辨率的场景.基于网络的并行渲染系统具有性价比高、扩展性好等特点,并且可以输出超高分辨率的画面,适合大型的虚拟现实场景展示.该系统使用Unity3D支持虚拟现实渲染和跨平台的特性,使用PC机群基于Sort-First结构的实时并行渲染框架展示弧形超高分辨率场景,并使用网络将手机、平板和PC机群连接在一起,利用增强现实的方式同步展示整个场景.该系统支持多机同时连接展示,可以应用到博物馆、教学、展览等领域.%Real-time display and interactive application in virtual reality are widely used recently.Since common PC has the performance problem when rendering,it is not possible to render ultra-high resolution scenes and ensure frame rates.The parallel rendering system based on the network has features of high performance-to-price ratio and good expansibility,and can output ultra-high resolution images for large-scale virtual reality scene display.Our system uses Unity3D to support virtual reality rendering and cross-platform features.It uses the PC cluster to display arc-shaped super-high resolution scenes based on the real-time parallel rendering framework with sort-first structure.What's more,it connects a mobile phone,tablet and PC cluster together to display the entire scene with the way of augmented reality.The system supports multi-machine display simultaneously and can be applied to many fields such as museums,teaching,and exhibitions.
