摘　　要：以槐树为例,构建了合轴分枝树木可视化模拟系统。根据可视化模拟的需要,指出了所需的形态结构因子及其与IFS因子的对应关系。以实测形态参数数据为依据,结合Logistic生长模型,基于IFS算法构建了槐树的三维模型。并以Direct X9.0为三维可视化平台,使用C#语言,采用面向对象设计思想完成了合轴分枝树木可视化模拟系统开发,实现了合轴分枝树木形态参数、生长模型参数设置以及模型输出等系统功能,较好模拟出合轴分枝树木静态与动态的三维可视化模型。Taking Sophora japonica as an example,a visualization system of sympodial branching trees was developed.The morphological parameters needed and the corresponding relation with IFS factor on request of visual simulation were studied.According to the measured morphological parameters and Logistic growth model,the three-dimensional model of S.japonica was constructed based on IFS algorithm.With DirectX9.0 as three-dimensional visualization platform and C# as programming language,the development of sympodial branching trees visualization system which adopting the idea of object-oriented programming was completed.The system could set the morphological parameters of sympodial branching trees and Logistic growth model output.The model which could well simulate the static and dynamic three-dimensional visualization of sympodial branching trees was established.
