基于关系模型的林分生长可视化建模
Visual Modeling of Stand Growth Based on Relation Model
摘要
Abstract
According to the specific tree Species of man-made forest,the relationship model of stand and trees were obtained by Bezier curve and the least-square method,which based on the measured data of a few trees,and then using a new kind of stand growth allocation method to calculate the tree model data of stand at any moment.The various tree visualization models of morphological structure were constructed by the stand growth characteristic param-eter and adaptive control of random variables.Results showed that the algorithm had low complexity and strong effec-tiveness.The stand growth model constructed by the new algorithm was consistent with the growth regularity of trees and has a strong sense of reality.关键词
