摘要
体视化技术主要研究包含物体内部信息的体数据的表示、变换、操作和显示等。土壤中元素空间分布的体视化对土壤中元素的空间分布规律及其污染评价、预测具有重要意义。对于理解土壤数据中蕴涵的土壤学信息,体视化比使用一组二维切片表示三维数据更自然、更清晰。文中基于Visual Studio 2005开发平台使用C#语言,引入三维可视化类库VTK,采用Kriging插值方法,实现了土壤中元素空间分布的体视化、三维交互以及任意剖切,同时给出了合肥市土壤的应用实例。
Volume visualization mainly studies the denotation, transformation, operation and rendering of the volume data which contains the inner information of spatial objects. The visualization about spatial distribution of elements in soils, which is of great significance to the spatial distribution feature of soil elements and pollution evaluation and quantification. Volume rendering is more natural and vivid than using a set of 2 - D slices for understanding agrolngic features presented in soils - date. In this paper, use C# language in the Visual Studio 2005 exploitation environment, import 3D visualization Toolkit and adopt Kriging interpolation method to realize the volume rendering, 3D interactive and arbitrary slice about spatial distribution of elements in soils. At the .same time, give the application of the soil in Hefei.
