摘　　要：分析了Vega软件环境中的基本视点方式,并阐述了其工作原理。针对视景仿真系统中视点行为可被自由控制的需求,设计了一种自定义的运动模式,通过与视点和鼠标外设关联,实现了基于鼠标控制的自由视点方式,论述了这种视点方式的工作原理和开发方法。应用结果表明:此视点方式灵活、易用,极大增强了视景仿真实验效果,补充完善了Vega的视点功能。The modes of Observe in Vega software environment are analyzed and summarized, and the work principle is discussed in addition. Based on the requirements of controlling observer freely in visual simulation system developed by us, a user defined motion model is designed. Then the motion model is correlated with observer and input device, and a kind of free observer controlled by mouse is implemented. The work principle and development process are discussed. The result shows that this flexible observer improved the effects of the visual simulation and extended the observer function in Vega software environment.
