Real time visualization with an evacuation simulation by using OpenGL fusion technique

We have been trying to show our disaster simulation outputs to people in an immersive virtual reality(VR) environment. Because we believe that the cooperation of residents is important for reducing the damage of the disaster. The tsunami runup is simulated with considering the buildings based on nonlinear dispersive wave theory by stabilized FEM. The result is visualized by using a visualization software: AVS/Express. The behavior of evacuees is simulated and visualized by using multi-agent simulator: NetLogo. The both 3D visualization are shown together in the VR environment by using OpenGL fusion technique. So far we have showed the animation after completing all simulations, but we have developed a prototype system that could show the animation while executing the evacuation simulation. In this paper, we introduce the architecture and show the visualization example by the system.
