早期核辐射毁伤效应空间建模及剖切算法

摘要

为了在3D GIS中实现早期核辐射毁伤效应可视化；提出了一种以多分辨率建模技术为基础的模型——MRPCT模型以及相应的模型剖切算法.该剖切算法采用了空间拓扑技术,可以实现毁伤空间任意角度的切割,从而全面揭示毁伤效果的空间结构特征；MRPCT模型实现了早期核辐射毁伤效应的三维空间数据模型的构建；为早期核辐射毁伤效应三维可视化和基于体元的空间分析与查询提供坚实的数据支持.%Aiming at the sake of implenting the early nuclear radiation damage effects visualization in 3D GIS, a new model k RPCT model is provided. On the basis of the technology of multi-resolution modeling,and the slicing algorithm for the MRPCT model is also given at the same time. Adapting the TOPO technology, the slicing algorithm displays the characteristics of spatial structure of the damage effects. And the MRPCT model provides data sustain for the 3D expression and spatial query and analysis of early nuclear radiation damage effects.
