三维分形树的虚拟仿真研究

Study on three-dimensional fractal dimension tree

首先介绍了模型树的构成和分类,讨论了模型树仿真时存在的问题,继而研究了如何利用迭代函数系统(IFS)仿真出树枝,并提出了一种结合IFS和布告栏的方法来仿真出三维树,最后,采用该方法拟合出2种三维树的分形模拟结果.模拟结果表明,该方法具有较高的真实性、多样性和实时性,对模拟三维场景有一定的实用价值.

This paper introduced the composition and classification of tree models,discussed the problem that branches and leaves with varying shapes be simulated by regulating their parameters.Then,we researched on how to use Iterated Function System(IFS) and billboard to simulate branches and leaves.Finally,by using this method,two classes of three-dimensional trees are simulated and applied to virtual scene.The results show that,three-dimensional trees simulated by this method have advantage of high vividness,diversity and real time response,which is valuable in 3D virtual scene simulation.
