为了直观、逼真地描述大型引水工程各环节之间复杂的动态时空逻辑关系 ,提出了大型引水工程三维可视化图形仿真系统 .首先 ,对引水工程三维可视化图形仿真系统进行系统分析 ,确定系统的开发模式 ,然后采集数据并进行仿真计算 ,再将所得数据以数据库的形式保存并对数据库进行加工处理 ,将空间数据 (矢量数据、形体数据等 )和各种属性信息集成在一起 ,在这些数据库的基础上建立引水工程三维可视化仿真模型及模型库 ,以方便对模型进行高效的管理 .开发了一个能科学、直观、逼真地表现大型引水工程施工的三维可视化图形仿真系统 ,为工程施工管理决策提供依据 .
In order to describe the complex dynamic space-time logic relationship between all aspects of large-scale water diversion project intuitively and vividly, a three-dimensional visualization simulation system of water diversion project is proposed.Firstly, a systematic analysis of the three-dimensional visualization simulation system of water diversion project is carried out to determine the development mode of the system , And then collect the data and carry on the simulation calculation, then save the data in the form of a database and process the database, integrate the spatial data (vector data, body data, etc.) with various attribute information, and on the basis of these databases A three-dimensional visual simulation model and model base of water diversion project are set up to facilitate the efficient management of the model.A three-dimensional visual simulation system is developed which can scientifically, directly and vividly represent the construction of large-scale water diversion project and provide basis for construction management decision-making .
