摘要： Vega提供了扩充自定义模块的功能。实现扩充的动态性通常只要在运行前设置其运动属性即可，而实现动态地形必须实时修改底层数据。该文提出一种修改Vega底层数据的方法，为Vega扩充了新的动态地形模块。实验结果表明，该方法具有较高可行性，应用效果良好。

Abstract: Vega provides the function of developing modules themselves for the users. The general dynamic extension only need set motional feature value at the beginning of rendering. The dynamic terrain need modify the bottom terrain data dynamically in the running time. This paper proposes an effective way to modify the Vega bottom data, and develops new dynamic terrain modules for Vega. Experimental results show that this method is feasible and works well.

Key words: Vega extension, dynamic terrain, OpenGL language
