摘　　要：在实时三维视景仿真的高性能软件Vega平台上,通过建立算法的数学模型,运用向量方法求出动态的视点位置和焦点位置,借助Vega API编程,实现了实时动态观察两个物体运动的全过程,并可以动态的调节视点,提高了视点控制的灵活性、可控性,增强了三维视景仿真的真实感和沉浸感。Vega is commonly used for three-dimensional scene simulation. By establishing mathematical model of algorithm and via using dynamic vector method, calculated the position of viewpoint and focus. Using Vega API for programming, the program helped observing the real-time dynamic movement of two objects for the whole process, and could adjust the viewpoint dynamically. This improved the flexibility and controllability of viewpoint, and enhanced the realism and immersion of three-dimensional scene simulation.
