摘要:

为克服了传统二维和三维模型结果显示的缺点,应用虚拟现实技术对城市给水管网进行分析研究,建立给水管网视景仿真平台,形成城市给水管网系统研究的新方法.通过给水管网虚拟场景与给水管网数学模型的有机集成,实现虚拟场景中给水管网的交互控制和计算结果的可视化显示.建模过程中将虚拟场景中实体按照相关图集绘制,保证模型具有较高精度,并通过相关算法对模型进行优化.本文通过程序设计建立了城市给水管网交互式虚拟仿真平台,实现了城市给水管网视景仿真系统.该平台不仅具有高度的逼真性,而且具有沉浸性、交互性的特点,用户可以直观的观察到深埋地下的给水管网,对给水管网进行交互控制,对管网工况进行可视化分析.

Abstract:

A urban water network was analyzed by the virtual reality technology in order to build a scene simulation platform of water network.And a new approach was appli on the study of water network system to overcome the shortcomings of traditional two-dimensional and three-dimensional models.The interaction and visual results were achieved in the virtual scene of the water network by integration of water network model and virtual scene.The objects in the virtual scene were built according to the standard atlas,which ensured that the model was with high accuracy.Then the model was optimized with relevant algorithms.The interactive virtual simulation platform of water network was built by programming in this paper and the scene simulation system of water network was realized,which was with the quality of verisimilitude,immersion and interaction.With the platform,the users can observe the water network lied underground directly,control the water network interactively and analyze the operation candition visually.
