分形几何学在自然景物计算机模拟中的应用初探

Computer Simulation of Nature Scene with the Method of Fractal Geometry

讨论了计算机图形学中的一个重要分支——自然景物计算机模拟中常用的几种分形方法.fBM方法、IFS方法、L-System方法等.利用以上方法,建立一些描述具体自然对象的数学模型,成功地模拟了山峦、树木、树叶和蕨类等自然景物.文中还给出了生成自然景物的一些算法,并显示了一些生成的图片.

The fractal method, often using to simulate the nature scene, is discussed. It pre-sents some methods (for example: Interated Function System, L-System, Fractal Brown Mo-tion etc. ) and builds some mathematics models. Using these models and methods, some na-ture scenes are simulated successfully, for example: terrain, tree, leaf and fern etc. There arealso given some algorithms to generate those image, and displayed some created image.
