Research on Fast Display Technology for Big Data Three-dimensional Model

随着三维模型技术的发展,生命线工程三维模型显示中存在数据量大、渲染时间长、显示处理运算压力大等问题。为此,文中构建了高度协同的分布式集群并行显示系统。在分析生成多分辨三维模型常用算法的基础上,提出了大数据三维模型的多分辨处理算法,通过建立多层次细节模型(LOD),实现了大数据三维模型的集群并行快速显示。实验结果表明,文中提出的大数据三维模型集群并行显示系统既可兼顾三维模型的显示速度,又可并行显示出模型的精细信息,为大数据三维模型快速、高分辨率显示提供了可行的解决方案。

With the development of 3D model technology,lifeline engineering 3D model shows the problem that the amount of data is large,the rendering time is long,and display processing operation pressure is high. To solve these problem,a distributed and parallel clus-ter display system is presented in this paper. Based on analysis of commonly used algorithms in generating multi-resolution 3D model,the large data multi-resolution processing algorithm of 3D model is put forward,by establishing a multiple Level of Detail （LOD） model,re-alize the cluster parallel fast display of big data 3D model. The experimental results show that the proposed 3D model big data cluster par-allel display system can give attention to display speed of 3D model,and show detailed information of the model in parallel,providing a feasible solution for quick and high resolution display of big data 3D model.
