【摘要】 针对城市水环境仿真要解决的重要问题是对城市内河流的水量状态与水质状态的描述,并枚举各种治理措施对水环境的影响。提出了在兼顾景观表现和实时显示速度的前提下根据真实地貌生成逼真的3D模型的方法,动态水的表现方法,汉字显示的实现方法,以及使用TCP/IP协议实现接收网络仿真数据的方法。利用以上提出的这些方法,实现了动态水的生成、水质变化、水量变化、污染物的表现,并且以显示三维物体的方式实现了二维汉字的显示。这些方法已经成功地运用到了城市水环境仿真中,并取得了很好的效果。更多还原

【Abstract】 The water environment simulation systems of cities put emphasis on solving the following problems: how to describe the water quality and quantity in the city rivers and enumerate how the different kinds of measures influence the water environment of the city.According to the problems above,this paper presents a method for generating a vivid 3D model based on the real physiognomy on the premise of ensuring view exhibition and real-time display velocity,what’s more,the display of dynamic water,the display of Chinese characters and how to realize the function of receiving net data with TCP/IP protocol is also put forward in the paper.With the methods listed above,the paper accomplishes the functions: the generation of dynamic water,the display of the variation of water quality and water quantity,and the display of contamination.How to display 2D Chinese characters by using the pattern for displaying 3D objects are also accomplished in the paper.The methods have been successfully applied to the simulations of city water environment and the simulations results show the effectiveness of the methods presented in the paper.更多还原
