Study on Visual Simulation of Fish Motion Behavioral Response Based on Unity3D

摘要: 本文利用Veryengine引警和Unity3D虚拟仿真技术设计了水生态环境模型和鱼类运动轨迹模型，并将两个模型进行叠加，构建了由水质指标查询模块、污染物迁移过程仿真模块和鱼类运动轨迹仿真模块的可视化仿真系统，对污染物进入水体过程中鱼类的运动行为响应情况进行了动态模拟。根据鱼类在不同水生态环境中运动轨迹变化情况，确定鱼类运动行为响应指并根据指标对水质状况进行评价，为水生态健康评价以及水生态修复效果评价提供参考依据。

Abstract: A visual simulation system was constructed by using Veryengine and Unity3D engine technology. It was consisted of water quality indexes query module, pollutant migration module and fish motion trajectories module, respectively by superimposing the aquatic environment model and fish mo-tion trajectories model. It can simulate dynamically the behavioral response processof fish to water quality evolution after the pollutants entered the water. According to the changes of fish motion trajectories in different aquatic ecological environments, the indexes of fish motion behavior re-sponse were determined and the water quality status was evaluated. It provided a reference for the evaluation of water ecological health and the evaluation of water ecological restoration effects.
