基于WebGL的水库大坝三维仿真系统实现

Realization of 3D Simulation System of Reservoir Dam Based on WebGL

针对基于插件的水库大坝三维仿真系统存在需要安装软件或插件等不足,采用WebGL技术实现了基于网页无插件的水库大坝三维仿真系统。首先,对水库大坝及周围地形进行三维建模,构建虚拟的水库大坝三维场景。然后实现水库闸门启闭模拟,水体效果模拟,船只航行模拟以及基于粒子系统的泄洪模拟,完成仿真系统的构建。最后接入水库大坝实时监测数据,实现大坝实时监测信息的展示。实践表明该水库大坝三维仿真系统,具有模拟效果更逼真,使用更便捷,集三维场景动态呈现和水库信息展示于一体等特点。

in view of the shortcomings of the three-dimensional simulation system of reservoir dam which is based on plug-in,we have implemented the three-dimensional simulation system of reservoir dam based on web page without plug-in by using WebGL technology.Firstly,we model the reservoir dam and its surrounding terrain in three dimensions,and construct the virtual reservoir dam in three dimensions.Then it realizes the simulation of reservoir gate opening and closing,water body effect simulation,ship navigation simulation and flood discharge simulation based on particle system,and completes the construction of simulation system.Finally,the real-time monitoring data of the dam is connected to realize the display of the real-time monitoring information of the dam.The practice shows that the simulation system of the reservoir dam has the characteristics of more realistic simulation effect,more convenient use,and integration of 3D scene dynamic presentation and reservoir information display.
