摘要：本文从IFS方法在树木建模中的应用出发,结合树木构筑学的特点,提出了一套树木形态数据的调查方法,以杉木为例在湖南攸县黄丰桥林场进行调查实验,通过对所采集的杉木数据的分析,获得杉木一级枝和二级枝枝长、枝根直径、仰角、方位角的分布规律,将其作为IFS变换的入口参数,构建杉木三维拓扑结构,并在.NET和D IRECTX9.0平台上开发了杉木可视化模拟系统,实现了杉木三维可视化模拟。
In this paper, some applications of IFS method in trees modeling were analyzed, and with the characteristics of trees architecture, an investigation method for the trees modality data was presented. Taking Cunninghamia lanceolata as an example, an investigation was conducted in Huangfengqiao Forest Farm of Youxian, Hunan province. By analyzing the data, some input parameters including the length, diameter, elevation angle and azimuth angle of its first-level, second-level branch were obtained, in order to make up three-dimensional topology of Cunninghamia lanceolata. The Cunninghamia lanceolata modeling system based on. NET frame and DIRECTX 9.0 was established, so as the Cunninghamia lanceolata three-dimensional simulating was realized.
