Abstract

The development of the global chemical industry has led to frequent leakage accidents of hazardous chemicals at sea, which has seriously affected the marine ecological environment. How to carry out rapid and effective emergency response has become an urgent need. The prediction and visualization of hazardous chemicals' future diffusion situation is an important part of the emergency process. At present, related researches on pollution diffusion visualization are still insufficient in the aspects of scene construction, rendering efficiency, scalability and interactive control. A three-dimensional dynamic visualization method for the diffusion process of marine hazardous chemicals based on the Unity3D engine and its particle system was proposed in this study. Based on the construction of three-dimensional scenes around the ocean and the optimization of model data, the visualization of hazardous chemicals diffusion process was achieved by dynamically updating the particles and interactive user interfaces for scene roaming and diffusion process control were provided. Taking Hangzhou Bay as an example, the simulation experiment results show that the performance and effect of this method meet the needs of practical applications. This method can provide information reference and auxiliary decision support for the emergency response of marine hazardous chemical leakage accidents.
