大型设施设计虚拟展示平台架构与实现

Virtual exhibition platform for large facilities design

面对现阶段虚拟展示平台存在的计算速度慢、沉浸感弱、展示规模较小等问题,以提升设计理念、扩展服务对象、简化设计的流程、缩短设计周期、降低设计成本为目的,提出建设基于计算机集群的大型设计虚拟展示平台,通过对该平台的需求分析,进行整体的架构设计,采用计算机集群技术进行大规模场景渲染和多线程、多种通信协议并行可视化等方法,最终搭建高效计算、按需传输的虚拟展示平台。

In the face of some problems,such as slow calculation speed,weak immersion and small display scale at the present stage of virtual exhibition platform,for the purpose to improve the design concept,expand the service object,simplify the design process,shorten the design cycle,reduce the design cost,this article proposed the construction of large-scale design virtual display platform based on computer cluster,through the demand analysis,carried out the overall architecture design.The key technologies were parallel visualization technology based on the multi thread and multi protocol and computer cluster technology which were used to render large scale scene and implement the virtual exhibition platform for efficient computation and on demand transmission.
