摘要
分析了基于二维图像的水污染模型计算结果可视化不足——脱离地形地貌环境、缺乏空间定位信息,提出基于虚拟现实的水污染扩散模拟三维可视化方法,讨论了数据组织与压缩、仿真模型与可视化一体化集成、查询统计等关键技术,对长江三峡库区万州段污染物迁移转化过程进行了动态模拟。结论表明,该方法形象直观地展现了水污染扩散推进三维效果,为检验污染模型的准确性提供了参考和依据,也为水环境综合整治与管理走向定量化、科学化提供了一种崭新的思路和可靠的技术支持。
There exists insufficient in the visualization of the calculation results based on two-dimensional images-separated from the terrain landform environment and lack of spatial positioning. The three dimensional visualization method of water pollution dispersion simulation was proposed based on the virtual reality. The key techniques such as data organization and compression, integration of mathematic model and visualization, the inquiry statistics and so on were discussed. The water pollution dispersion process, in Wanzhou Yangtze River Three Gorges Reservoir area was simulated dynamically. Conclusion indicates that, this method unfolds the water pollution dispersion three dimensional effects visually and lively. It provides not only a reference to check out the accuracy of water pollution calculate model, but also a new way and dependable technique support to synthetically manage of water environment according to quantitative and scientific standard.
