基于Cesium的气体扩散可视化系统

Visualization System of Gas Diffusion Based on Cesium

气体扩散是一种常见现象,搭建高效的可视化系统,对探索气体扩散规律并做出快速、准确、普适性应对具有重要意义。本文针对目前气体扩散可视化存在的不足,提出建立基于Cesium的气体扩散可视化系统。系统采用B/S架构,在服务器端采用高斯烟羽模型对气体扩散进行模拟计算,在客户端完成气体扩散可视化效果。着重讲述了可视化效果的方法改进与过程实现,完成了使用canvas绘制热力图并将其与Cesium地图引擎结合的应用。

Gas diffusion is a common phenomenon. Building an efficient visualization system is of great significance to explore the law of gas diffusion and make a rapid, accurate and universal response. In view of the shortcomings of current visualization of gas diffusion, a gas diffusion visualization system based on Cesium is proposed in this paper. The system uses B/S architecture, and the Gauss plume model is used to simulate the gas diffusion on the server side, and the visualization of gas diffusion is completed on the client side. This paper focuses on the improvement of visualization method and the realization of the process, and completes the application of drawing thermal map with canvas and combining it with Cesium map engine.
