The Fractal Brown Motion (FBM) is an important content of thefractal geometry. Using the FBM method, we can develop manythree- dimension geometrical models with fractal characteristics,such as mountains, clouds and so on.

• 分形布朗运动FBM是分形几何的重要内容，利用它可以构建出极具分形特性的三维几何模型，这种几何模型可以用来生成多种不同的自然对象，如山脉、云彩等的真实感图形。
