三维视景仿真系统中仿真过程管理的研究

摘要

三维视景仿真系统的仿真过程管理一直是计算机图形学领域的热点之一.三维视景仿真系统的研究主要集中在虚拟环境的真实性方面,仿真过程管理的研究还没有被很好地解决.文中按照功能将三维虚拟视景仿真系统分为七个模块:数据输入、键盘输入、配置文件、消息映射、场景控制、仿真环境显示、数据记录；又从用户角度划分出三个模块:输入模块、处理模块和输出模块.同时,文中提出了配置文件和三维模型XML描述两种关键方法,分别用来存储仿真环境相关数据和简化模型调用方式,提高了虚拟仿真系统的通用性.此方法在三维视景仿真系统的开发过程中成功地进行了应用.%The simulation process management of the three-dimensional visual simulation system has been a hot research field in computer graphics. The research of three-dimensional visual simulation systems mainly focuses on the authenticity of the virtual environment,however,the research on the simulation process management has not been well addressed. According to the functions,the three-dimensional virtual visual simulation system is divided into seven modules; data input, keyboard input, configuration files, message mapping, scene control,simulation environment display,data recording;And from the user's points of view,it's divided into three modules:input module ,processing module and output module. At the same time,proposed two key methods,the configuration files and the XML descriptions of the three-dimensional models; They are used to store the simulation environment-related data and to simplify the calling of the models respectively, which improves the versatility of the system. This method has been applied successfully in the developing process of the three -dimensional visual simulation system.
