Abstract: Aiming at the problems of high population density, difficulty of organizing fire training efficiently and lack of experience in dealing with emergency events in campus, a virtual simulation training method based on DI-Guy software is proposed. First, we build the three-dimensional model of campus using MultiGen Creator software and load it into the visualization window of DI-Guy for construction. Then we simulate the fire scene and the process of fire evacuation. Finally, we analyze the effect of crowd evacuation scheme. At the same time, some key technologies in the simulation process, including the establishment of user-defined model, the realization of special effects, the behavior control of characters and collision detection, etc, are researched and applied. The simulation results show that the proposed simulation model can reasonably reflect the crowd evacuation situation and play a good display role. It provides a feasible scheme for the simulation of campus emergency events on DI-Guy platform.
