超大规模地学数据多尺度并行抽取与远程可视化实现

Multi-scale parallel extraction and remote visualization for large-scale data in geosciences

集中并行可视化与远程可视化的优点,提出远程数据抽取与并行可视化分析诊断方案.针对地学研究对象具有多尺度的特点,借助于多尺度、多分辨率数据抽取工具,建立了超大规模地学数据多尺度抽取算法以及并行实现算法;并以海啸数据为例,基于VTK软件实现海啸数据的多尺度显示.

In this paper we focus on advantages of the parallel visualization and remote visualization,and propose a new scheme： remote data extraction and parallel visualization analysis diagnosis.For the multi-scale feature of geological research objects,we establish a multi-scale extraction algorithm and corresponding parallel algorithm of large scale geological data with the aid of multi-scale and multi-resolution data extraction tools.Finally,we realize the multi-scale display of tsunami data based on VTK software.
