摘要
由于受到硬件条件的限制,大场景虚拟现实一直难以在Web上应用。分析了限制大场景虚拟现实应用尤其是在Web上应用的三大瓶颈,分析了LOD策略模型的技术特点及其存在的缺陷,提出了一种新的分块策略模型。基于该分块模型和XML技术,提出了一种可以克服CPU、内存、网络带宽三大瓶颈的技术方法,使大场景模型能在普通计算机及不太高的网络环境上运行,使大场景的Web虚拟现实应用能成为现实。
Because of the restriction of the hardware, virtual reality technology of large scene can hardly be used on Web. This article analyses three bottlenecks on large scene application of virtual reality, and discusses LOD strategy and its default. A new block strategy is offered. Based on this block strategy and XML, a method that could overcome the bottlenecks of CPU, RAM and bandwidth is raised. Using this method, models of large scene can run on common computer and net environment.
