摘要
基于工程实际阐述了采用Di rect 3D技术实现三维空间态势显示的方法,包括态势显示模块构成及若干关键技术的设计思路和解决办法,重点叙述了应用ActiveX实现模块化的技术原理和实现细节,以及如何正确应用四元数计算空间旋转,避免欧拉角计算中的万向轴死锁问题。该方法应用在某态势监视系统中,性能稳定,运行效果良好。
According to practical software engineering requirements, the space situation 3-D display system based on direct 3D technology was designed. The structure of module, design method and solution of key technology are introduced. This paper puts emphasis upon the technical principle and implementation details of using ActiveX component technology to realize modularization, and how to correctly apply the quatemion to compute the spatial rotation and avoid 8~bal locking in Euler angle computing. The application in a situation monitoring system indicates that this method has stable performance and better operation efficiency.
