From their Environment to their Behavior: A Procedural Approach to Model Groups of Virtual Agents

Abstract. Simulation of everyday situations from real life can be a very useful tool in entertainment applications and training systems. Such applications, as games or computer animated movies usually need to provide virtual environments populated with virtual autonomous agents. Commonly, the agents need to be able to evolve in their environment, avoiding collision with each other and obstacles, besides interacting with other characters in order to provide realistic simulations. We present a model to simulate coherent group behaviors based on procedural modeling and semantic environments. Our main focus is virtual environments and agents, present in the background of games or movies generated with few/without user intervention.
