摘　　要：为满足用户浏览场景时自由控制视点的需要,同时实现视点避碰的功能,剖析了Vega环境中视点的工作原理,介绍了用户自定义运动模式视点的工作流程,开发了具有碰撞检测、能做出正确响应、可键盘控制功能的视点方式,提出了可行的碰撞响应策略。在导弹拦截系统的仿真应用中,该视点方式灵活易用、可操作性好,提高了用户浏览场景时的灵活性,大大增强了用户浏览场景时的真实感和沉浸感。To meet the requirements of controlling observe freely, while users scaned the scene, and to realize the function of observing collision avoidance, the work principle of the viewpoint in Vega’s condition was anatomized and the work flow of the user-defined motion model observer was introduced, and the observer mode with the function of collision detection was developed which could respond rightly and could control by keyboard,and the workble responsive strategy of collision was introduced. In the visual simulation application of missile intercepting system, this observe mode is flexible and easy to use, and has good maneuverability. It improves the agility and greatly enhances the facticity and the immersion, while users scan the scene.
