VR技术在渠系仿真中的应用

Application of VR technology to simulation of channel system

在宝鸡峡杨凌二支渠灌区数字化研究中,利用虚拟现实技术初步构建了渠系仿真系统。提出了一种对渠道所在区域宏观表现和微观把握的方法;采用模型简化技术,解决了不规则渠道模型的构建问题;给出了水波控制、碰撞检测和速度优化方案;实现了漫游、查询和交互式控制功能。

Based on the digitalization research of Yangling Irrigation Area of the second branch channel within Baojixia Irrigation District, a simulation system for the irrigation system is primarily developed with VR （Virtual Reality） technology. A realizing method of displaying both the macro-scene and the micro-scene of channel site is put forward. With the simplified model method, the problem of building the model of irregular channel is solved. Furthermore, the scheme for water wave control, collision detection and speed optimization is also given herein, and then the relevant VR functions of walkthrongh, querying and interactive control are realized as well.
