摘　　要：树木三维模型在农林业和娱乐、教育、商业等非农林业领域有着广泛的应用,但现有树木建模方法缺乏通用性:针对不同的对象需要建立不同的模型。运用递归调用分形自相似结构的方法构造了树木的三维模型。通过使用分枝结构随机抖动与双缓冲技术,兼顾了模型真实感与实现速度的问题。结果表明,该方法具有良好的通用性,简洁高效,能生成逼真的树木图形。The 3D model of tree is widely used in agricultural research and other areas such as show business, education, business, etc. At present, the methods of tree modeling cannot be used universally： different applications need different models. This paper presented a shape model of 3D tree based on fractal. The use of random-trembling and double-buffer technique takes beth the third dimension and the speed of calculation into consideration. As a result the method has good un/versality, it can be carried out easily, and can make lifelike tree sketch.
