摘要
针对大规模场景实时性浏览中的数据调度问题,提出了一种采用Hilbert空间排列码的大规模场景数据调度策略。该策略利用Hilbert空间排列码良好的空间聚集性能,同时采用了一种高效的Hilbert空间排列码生成方法,能够有效提高大规模场景数据调度时的效率。试验结果表明,与基于四叉树的调度策略相比,构建时间相当,随机读取效率显著提高。
In the view of data scheduling of real time browsing in large-scale scenes,a data scheduling strategy using Hilbert space arrangement codes is proposed. This strategy can significantly improve the efficiency of data scheduling in large-scale scene by utilizing the better space convergence performance of Hilbert space arrangement codes and adopting a high-efficiency Hilbert space arrangement code generation method. The experimental results show that compared with the quad-tree scheduling strategy,the proposed strategy has such advantages as short construction time and higher random reading efficiency.
