摘要： 针对断层算法所产生的地形刻痕明显并且缺乏细节的缺点，提出一种地形生成方法。使用断层算法生成初始的地形高度场来描绘地形的宏观轮廓，使用线性滤波算法对高度场进行平滑滤波处理以消除地形刻痕，使用分形算法对高度场进行迭代处理以增加多层次的地形细节。实践证明，用该方法在普通PC平台上能够生成真实感较强的地形。

Abstract: Aiming at the fault of fault method, the paper presents a new method for terrain generation. Fault method is used to generate height field of terrain, and then a linear filtering algorithm is constructed to smooth the height field to eliminate the nick. The fractal method is put into use to add multilayer details for terrain. This method results in natural terrain with rich details and reality. Test results show the method is practical in virtual environment and realistic terrain can be generated on general PC platform.

Key words: terrain generation, fractal, fault method, virtual environment
