摘　　要：基于Vega构建的虚拟维修仿真系统不支持鼠标拖动的交互方式,对鼠标控制三维实体实时移动的交互控制方法进行了研究;分析虚拟现实仿真中存在的坐标系及其变换关系,建立了仿真实体实时移动时在世界坐标系、观察坐标系和屏幕坐标系下的映射点关联模型,利用仿真实体在虚拟环境下移动存在的恒定参数关系获取位移关键点坐标,求解仿真模型实时移动映射点关联模型,从而实现了仿真实体的实时移动控制;将实时移动算法应用于虚拟维修训练仿真系统,实践证明,改进后的系统实时性和通用性明显加强,交互更加方便灵活,扩展了虚拟维修训练仿真中的交互方式。Real--time Moving of model is not supported in virtual maintenance simulation system based on Vega. Make an research on real--time moving method of virtual maintenance simulation model The relationship among world coordinate system, view coordinate system and screen coordinate system is analyzed. Coordinate mapping model is set up. And then, figure out the real--time moving mapping model based on constant parameter. At last, the method is applied in virtual maintence training simulation system. It had proved that the ameliora- ted system was more real--time and universal. The method expand the interaction mode, which makes the interaction more convenient.
