摘　　要：Vega作为一种优秀的视景仿真软件,在军事仿真、城市规划等很多领域应用广泛,但Vega只提供了西文字符的显示,并不支持汉字的显示,这就给某些视景仿真系统的开发带来了一定的困难。在对Vega研究的基础上,采用OpenGL回调技术,实现了Vega中汉字的二维及三维显示。该方法可用于大型分布式仿真环境中,与Vega提供的vgFont功能相比,显示速度有明显提高,具有较高的实时性和一定的可移植性,对Vega环境下其他仿真特效的实现有一定的指导意义。As an excellent software of scene simulation, Vega has already been used in every field, such as military simulation, city programming and so on. But Vega only provides the display method of western characters, doesn＇t support the display of Chinese characters, and brings many difficulties to the development of some scene simulation systems. Based on the analysis of Vega, the call- back technology of OpenGL is used, and the Chinese characters two-dimension display and three-dimension display in Vega are realized. The method can be used in the large-scale distributed simulation environment. Compare to the vgFnot function which is provided by Vega, the display speed is increased obviously, and it has higher real-time and some transportability, it also has some guiding significance for the realization of other simulation specificity in Vega.
