摘　　要：植物是自然场景中的重要组成部分,但由于其结构的高度复杂性,给模拟植物带来了极大的困难。运用分形递归算法,构造了参数可变的三维树木通用模型。通过纹理贴图、Bezier曲面和阴影效果增强了植物的真实感。同时基于OpenGL图形库函数制作出了植物开花结果的实例。Plants play an important role in the natural scenery of landscape. Unfortunately, due to the high level complexity of the structure of plants, simulating tree becomes extremely difficult. The paper used fractal reeursion algorithm to construct the 3D tree model whose parameters were variable. We took advantage of texture mapping, simulated shadow and made use of Bezier surface to enhance the sense of reality of the project. A test example of blooming in a tree created solely by OpenGL graphics library was provided to show the feasibility of the algorithm.
