摘　　要：基于LinkVR适配技术,构建沉浸式虚拟现实场景;针对场景的布局、结构和特点,运用Profile等相关手段进行性能分析,寻找主机资源消耗的关键点;通过烘焙、遮挡剔除和LOD等技术手段,对虚拟场景进行优化。文章以虚拟ICU为案例,叙述了一种沉浸式场景的构建方式,总结了对沉浸式复杂场景进行性能优化的关键技术。LinkVR adaptation technology can be used to construct an immersive virtual reality scenario.Aimming at the layout,structure and characteristics of the scenario,the key points of host resource consumption would be found with the performance analysis using Profile and other related means.The virtual scenario is optimized by baking,occlusion elimination and LOD and other technology means.In this paper,taking virtual ICU as an example,the construction way of immersive scenario is narrated,and the key technology for the performance optimization of immersive complex scenarios is summarized.
