Indoor evacuation model can provide scientific guidance for security solution design and emergency plan making in indoor environment, and virtual 3D scene can make the evacuation simulation more intuitive. An integration method of multi-grid evacuation model in 3D virtual indoor environment is proposed here. It maps 3D scene to 2D plane and establishes the grid table first, and then for each grid, calculates the shortest distance to accessible exits. After that, using the route selection method of multi-grid model to calculate the target position for each pedestrian in one time-step and matching the position to 3D scene, and invoking the action library to simulate the movement. Besides, the effect of ground slope is taken into account on pedestrian velocity. Experiment shows that the method is feasible and effective.
