基于WebGL的小型湿地风浪动态模拟研究

WebGL-based Dynamic Simulation of Wind Wave in Small Wetlands

针对现有方法在风浪动态模拟方面可视化效果较弱、难于交互等问题,提出了一种风浪模型与WebGL耦合的动态模拟方法。基于WebGL技术绘制了风浪的三维场景,采用Three.js主流图形库,结合粒子系统,实现了多种条件下小型湿地风浪的动态模拟。实验结果表明:该动态模拟方法可行,且具有良好的鲁棒性,给用户提供了更加沉浸的交互体验与逼真的仿真场景,也为湿地管理提供了新的决策支持。

Aiming at the problems that the existing methods have weak visualization effect and difficult interaction in wind wave dynamic simulation,this paper presents a dynamic simulation method coupling wind wave model with WebGL.The three-dimensional scene of wind wave is drawn based on WebGL technology.The dynamic simulation of wind wave in small wetlands is realized in different conditions with Three.js mainstream graphics library and particle system.The experimental results show that the dynamic simulation method is feasible and robust,provides users with more immersive interactive experience and realistic simulation scenes,and also provides new decision support for wetland management.
