树木可视化模拟首先是树木形态结构的模拟,对树木形态结构的准确了解对于提高模拟精度至关重要.杉木是我国特有的重要用材树种,从杉木可视化模拟的角度出发,针对杉木的形态结构建模所需的参数,从杉木的整体信息和分枝信息两个方面设计了杉木形态结构调查因子,并提出了相应的调查方法.对所调查的杉木数据进行了统计分析,得出了杉木的结构特征:杉木一级枝仰角主要分布在60°～90°内,方位角基本属于均匀分布,二级枝分布在水平方向上;随着枝下距的增加,枝长减少;枝长越长,子枝个数越多.

Tree visualization is the first step for simulating the morphological structure. It is very important to know the morphological structure for improving the simulation accuracy. To get the parameters of morphological structure modeling of Cunninghamia lanceolata, we designed the survey factors of morphological structure and introduced relevant survey methods based on visual simulation in the study. Then we made a statistical analysis of the data and concluded the morphological and structural features of Cunninghamia lanceolata. The branching angles of primary branches are mainly distribute from 60°to 90°, the azimuth of primary branches follows uniform distribution and the secondary branches mostly distribute in horizontal direction, distance from a branch attachment region to its parent container has a good correlation with the branch length, branch length has a great relevance to the number of sublevel branch.
