Research on large-scale pedestrians´ evacuation simulation model in three dimensional environment

In order to model and analyze the 3D simulation process of Large-scale pedestrians´ evacuation, MATLAB and VC++ mixing program method is used to set up the simulation frame. VC++ is used to extract the geometry information of the general arrangement drawing, and OPENGL toolkit is used to draw 3D structure model and virtual human model. MATLAB is used to set up mathematical model base on cellular automata theory. Besides the calculation speed is improved by using array data storage to take the place of matrix data storage. Finally, the simulation in single room and multi-level exit room is used to verify the efficiency and practicability of the model´s building method in this paper.
