Development of Adverse Weather Simulation System in Accident Reconstruction

According to the problem that lots of traffic accident happened under adverse weather conditions,we analyzed the influence of it on vehicle safety,and researched on the reconstruction of accidents under adverse weather conditions. Using particle system to simulate rain and snow weather in real-time,we applied Open GL fog effect on foggy weather simulation and reduced vehicle braking trace on the basis of the establishment of weather simulation system. Finally we reconstructed a real accident,and the result turns out that this system can provide accurate and realistic basis of accidents under adverse weather conditions.
