摘　　要：介绍了fBm方法的基本原理和特点,给出了在三维空间中用中点偏移法生成山脉地形数据模型的算法,提出了一种基于OpenGL山脉地形真实感显示方法,并通过实例验证其科学性和可行性。After introducing the principles of the method of the fractal Brown motion,this paper describes an algorithm to perform fBm with computer that is called the mid-point displacement method.After that,a technology is suggested to display the three-dimension fractal terrains based on OpenGL.At the end of the paper,a few of graphics built by a VC++program are provided to prove the usefulness of the methods.
