Application Of Harbin’s Water Pollution Emergencies Based Unity3D

In recent years, as China’s urbanization is accelerating, sudden water pollution incident has become a potential threat to our water safety and water quality. In the event of water pollution incidents, caused serious environmental problems. Harbin Songhua River Basin River Basin area of numerous point sources, non-point source dispersion, ditches, rivers, and other water environment monitoring point information complexity, when the river burst river water pollution accident occurred when the traditional approach to environmental management is difficult to accurately describe the monitoring any of the range of a water quality monitoring points, unable to make a realistic display of the current state of pollution, and therefore need to expand the use of virtual reality technology is now a systematic study of sudden water pollution incidents virtual.In this paper, the research scope of Songhua River in Harbin, the establishment of property library to build a three-dimensional model and SQL server through SketchUp, and application development engine Unity3 D establish a Virtual Reality Geographic Information System. The system is full screen interactive virtual reality technology, the scene edit, add, and other aspects of the advantages of the script, based on the proposed water pollution incidents Unity3 D the Songhua River in Harbin watershed Virtual Reality Geographic Information system design and development methods, and implemented space to roam, attribute query, distance calculation, such as the amount of the basic functions of GIS and particle system to simulate the spread of pollutants in the river. So the virtual reality technology and geographic information systems applied to the combination of water pollution monitoring to go, has incomparable advantages, but also will be the future of environmental monitoring program visualization of a trend. Geographic information system platform for the virtual research environment for resource monitoring department for visualization of the Songhua River water pollution as technical support.
