Abstract

Abstract: The sudden accidents usually emit large quantities of toxic gases and harmful pollutants in a short time. It is very necessary and meaningful to predict and visualize the dispersing trend of those toxic gases over Internet as accurate and fast as possible for people to evacuate safely and immediately. We propose a lightweight simulation for air pollution dispersion based on the Gaussian puff model. With this method, we can visualize the procedure of toxic gas dispersing on a webpage in real-time. we can also estimate the pollution of toxic gas dispersion trend and analyze their further pollution effects on the surrounding environment under different air conditions. We implement our ideas with Three.JS framework in a Web3D manner. With the help of this platform, users can not only manage all kinds of toxic gas dispersion model data, but also set up the data of toxic gas dispersion, which is convenient for pubic to use.
