摘要
在视景仿真系统中建立多种二、三维表现形式并保持它们之间数据一致具有重要意义。该文结合MFC和Vega系统的特点分析了二、三维联动基本原理,提出了集成MFC和Vega平台的多文档视景仿真系统框架,既避免了Vega在多文档开发中的不足,也充分发挥了MFC的多文档功能;然后,以MFC的消息通讯机制为基础,设计了二、三维多文档系统信息交换机制和数据交换表,保证了二、三维系统在运行过程中数据的一致性;最后开发了多文档的卫星运动视景仿真程序。
<Abstrcat>It is important to build multi expression in 2D and 3D and keep the consistency of their data in the system of virtual reality. Combining the features of MFC system with ones of Vega, this paper analyses the basic 2D and 3D associated principle, proposes a multi-document system frame of virtual reality simulation, which integrates MFC and Vega platform. The frame avoids the error of Vega in the multi development and exerts the function of multi-document of MFC. Secondly, based on the communication mechanism of MFC, this paper designs the mechanism and tables of message exchange between 2D and 3D multi-document systems, which keep the consistency of data of 2D and 3D systems when those systems run. Finally the author developed the multi-document virtual reality system for satellite motion.
