空间高维数据可视化方法研究

Visualization Methods in Spatial High-dimensional Data

基于可视化层次降维的基础上提出一种虚拟环境层次结构降维方法.该方法对建筑物密集地区飞行路线进行了仿真实验.实验结果表明,在一定的空间索引数据结构上使用虚拟环境层次结构降维方法具有更加突出的优点,在不影响视觉效果的前提下,极大的提高三维场景的漫游速度,实现更好的降维效果.

A kind of virtual environment hierarchy dimensionality reduction method is proposed based on vir-tual hierarchy dimensionality reduction which is simulated for building dense regional flight route. Without affect-ing the visual effects, experimental results show that virtual environments hierarchy dimensionality reduction method in a certain space index data structure has a more prominent advantages than others in achieving better dimension reduction, which greatly improves the speed in three-dimensional scene roaming.
