摘要
该文设计了一个基于面向对象空间数据库的三维地景(terrain)可视化系统,并依据人们对地图的理解角度提出了面向对象的四级数据模型,研究了场景生成技术,开发了底层的面向对象的空间数据库。系统具有良好的通用性和可扩展性,在飞行模拟、实时动态仿真及虚拟现实等领域有较广泛的应用前景。
This paper designs a3D(three-dimensional)terrain visualization system based on object-oriented spatial database.According to the points of view for map comprehension,a four-leveled data model is presented,the technology of scenery building is studied,and an underlying object-oriented spatial database is developed.The system designed has good compatibility and extensibility,and it has widespread availability and prospect in the domain of flight simulation,real-time dynamic simulation,virtual reality,etc.
