摘要
分布式思想及面向对象方法在虚拟环境的研究中有着重要意义，尤其是在处理复杂的应用系统方面．在一个实际的虚拟环境应用系统中，存在下列3个需要考虑的问题：①复杂模型的表达；②参与者的控制；③网络通信．从系统角度看，虚拟环境系统可分成算法层、关系层、概念／行为层等若干层次．在这种分层思想的基础上，提出了基于行为的面向对象模型，采用传统的面向对象思想来描述该模型，同时将CSP模型中的通信原语揉合进对象模型中，以解决分布式环境中的通信问题．该模型已在自主式移动机器人体系结构仿真系统中得到应用，仿真实验证明了该模型的有效性．
Distributed technology and object-oriented analysis method play an important role in virtual environment research, especially in complex application. In a practical virtual environment system, three problems should be considered: ①the expression of complex model, ②the behavior control of the user, and ③the network communication. From the system architecture's point of view, there are three layers- algorithm layer, relationship layer, and behavior layer in a virtual environment system. A behavior-based object model is proposed in this paper according to the above analysis. This model is expressed using the traditional object-oriented method, and the communication primitives in CSP model are also embedded in it to solve the third problem in the virtual environment system. The model has been applied in the simulation of an autonomous robot architecture and has been proved to be efficient by the experiment result.
