The Pivotal Multiple Entity Behavior Simulation Technologies Of Virtual Scene

Scene simulation is an interactive environment based on calculable information. Because it can help people to establish the environment that has immersion be personally on the scene, interaction to complex system, imagination and creativity, so it can become the necessary high-tech technology in every social application field. Nowadays, scene simulation technology has become one important portion of simulation system software, and it's also become primary content of virtual reality and distributed interactive simulation.Based on the characteristics of high real-time and interaction, the paper designed system function, analyzed technology course, advanced holistic frame and confirmed the software/hardware framework and the development environment with MultiGen Creator/Vega.The paper particular introduced the multi-entity behavior simulation under the VR environment, researched the simulating entity behavior abstract of visual system, and realized several important concepts and methods. Based on the model-oriented simulation, discussed the modeling method of behavior collaboration and corresponding between multi-entities, analyzed the feedback mechanism of entity behavior strategy simulation of XML oriented configuration, and last used agent-oriented modeling & analysis method, combining AUML technology for system modeling, realized the real-time simulation of virtual reality system.After summarizing the theory clew and its'characteristics, the paper considered the multi-entity behavior simulation system with complex scene as a typical CAS, and agent-based system analysis would do good for solving relative questions. After studying the UML in object-oriented technology, the paper extended it according the prime demand of agent-oriented technology. Then AUML was proposed. It could help the application of agent-oriented system simulation technology as a tool.The paper mainly researched behavior abstract about simulating entity in a scene system. Firstly definitely expatiated the characteristics of model-oriented simulation; based on this bring forward a four-layer means for simulating entity behavior description; and advanced some concepts and methods like'function encapsulation'and'movement intersection'for agent-oriented entity simulation, also put forward corresponding and collaboration models; all of this pointed out a fresh understanding on achieving the research of complex scene & multi-entities behavior simulation.By taken use of XML technology realized the data stream description of simulating entity, dynamically and interactively finished the simulation with different behavior strategies as the input of system, and provided simple implementing mechanism for system designer to validate performance and to evaluate project; what's more, the extensibility of application software would be enhanced and be more haleness and universal.
