摘要
随着计算机技术的快速发展以及三维地理信息系统的部门化的发展趋势,构建一个可视化、数字化、信息化、智能化的水利领域三维可视化系统不仅是必要的而且是可行的,要实现这样一个系统,三维可视化是基础,只有在可视化的环境中才能将各种数据和信息及时、动态、直观地反馈给用户。
     本文在吸取了计算机图形学、现代数学、计算机科学、测绘学等众多领域大量先进理论成果的基础上,系统的论述了三维可视化中的三维空间中数据结构、地形地物三维可视化的理论、技术和算法,包括三维空间数据结构的设计、地形三维可视化的基本理论、地形三维动态显示技术、地物与地形的匹配与显示技术以及基于三维地形图的空间查询技术。
     作者结合参加水利部科技创新项目“引江济太三维模拟系统”的经验体会与实践以本论文的理论研究成果为基础开发了一个适用于水利领域的三维可视化系统。该系统具有能够接受不同格式的DEM数据并进行预处理,实现地形的三维可视化和实时动态显示,地物在地形中的显示以及三维空间分析、查询等功能。
     本文研究具有重要的理论和实践意义,在理论上,从数据结构,构建地形、地物与地形的匹配显示进行研究。在实践上,本研究是实现数字地球和三维GIS入门的基础;是实现三维可视化地图的关键;在数字水利中具有重要意义,为水利领域的三维可视化系统提供了一个值得借鉴的系统原型。
With the fast development of computer technology and the specialization trend of 3D GIS, it is necessary and realizable to building a visible, digital, informational and intelligentized system with the three-dimensional visualization foundation, only in which variable of data and information can be fed back to users in time, dynamic and straight.
    Based on lots of advanced results of computer graphics, modem mathematics, computer science and topography, etc. this thesis discussed the theory, techniques and arithmetic of three-dimensional visualization, such as the data structure based on three-dimensional space, terrain and object modeling techniques, basic theory of three-dimensional terrain visualization, dynamical three-dimensional terrain display, matching and display technology between terrain and objects and spatial query within three-dimensional terrain maps.
    At last, based on the researched result of the above problematic situation, the three-dimensional visualization system applied to water conservancy has been established combining with experience and practice in the item of "3D-Dynamic Simulation System (derivating the water from Changjiang to Taihu Lake)". Varity of data can be received and pretreatment, three-dimensional visualization and dynamical display of terrain, object display on terrain, and spatial analyses and query.
    This investigation has important theoretic and practical meaning. In theory, we investigate the data structure, designing terrain and matching technology about models in terrain. In practice, it is the basic of the global realization and 3D GIS introduction; it is the key to realize the 3D visualization map; it is important in the "digital conservancy", and provides a archetype system for the 3D visualization system in conservancy area.
