利用偏最小二乘回归分析三维可视化系统的硬件影响因素

Analysis of 3D Visualization System Hardware Interfering Factors with Partial Least-Squares Regression Method

  • 摘要: 在多种配置的计算机上对全球多地区多级别的三维地形进行漫游测试,得出实验数据,然后利用偏最小二乘回归方法,对三维可视化系统中影响系统性能的11个硬件因素进行了分析。实验结果表明,影响三维可视化系统的主要硬件因素为CPU主频、二级缓存和内存,其中,二级缓存对可视化系统运行速率的影响尤为显著。

     

    Abstract: We get some experiment data by flying on global multi-area and multi-level 3D terrain at different machine configuration.Then using the method of partial least-squares regression,we do study and analysis on the 11 hardware elements which affect 3D visualization system running capability.There is high collinearity in the data,making the least-squares regression not reliable.Using the partial least squares regression,the effect of collinearity can be mitigated effectively,and the affected complexion about 3D visualization system running efficiency by hardware elements can be easily reflected.We conclude that the main hardware affecting elements to 3D visualization system are CPU basic frequency,L2 Cache,and Memory,and L2 Cache plays an important role on the running speed of 3D visualization system.
