仿真技术是一门综合性很强的技术,具有可靠、无破坏性、可多次重复、安全、经济、不受气象条件和场地空域的限制等特点,在军事、工程、航空、航天、医学、建筑等领域得到了广泛应用。视景仿真技术是数值仿真技术与计算机图形学最新成果的结合,它在数值仿真的基础上,以图形和动画来表示仿真的过程或结果,以三维模型的实时真实感动画显示技术应用于模拟训练、虚拟现实以及其他实时动态仿真系统的图形显示,尤其是在军事领域,这一技术成为近年来研究的热点之一。 Simulation technology is a very comprehensive technology with reliability, non-destructive, repeatable, safe, economical, free from meteorological conditions and the constraints of the airspace and other characteristics of the military, engineering, aviation, aerospace, medicine , Construction and other fields have been widely used. Visual simulation technology is the combination of numerical simulation technology and the latest achievements of computer graphics. Based on the numerical simulation, it shows the process or result of the simulation by means of graphic and animation. The real-time realistic display technology of the three-dimensional model is applied to the simulation Training, virtual reality and other real-time dynamic simulation system graphical display, especially in the military field, this technology has become one of the hot spots in recent years.
