基于IFS的单子叶盆栽植物仿真研究

Realistic Simulation of Potted Monocot Plant Based on IFS

单子叶盆栽是植物造景和美化环境不可或缺的植物之一,本文以单子叶盆栽为研究对象,以函数迭代系统理论为基础,建立了形态特征参数可调的单子叶盆栽的枝干、枝条、枝叶三维几何模型,从而构建了盆栽几何模型;同时考虑到枝条分叉结构的自相似性与随机性,建立了剪枝操作模块,通过仿射变换矩阵与几何模型之间的关系,以较高的自由度完成了枝条形态修剪可视化,得到较为逼真的计算机模拟结果,可为盆栽植物造型研究、市场选购提供一定的指导作用。

Potted monocot plants are one of the most indispensable plants for landscaping and environment. This paper establishes 3D geometric model of branches, twigs, branches and leaves of potted monocot plants with adjustable morphology parameters based on iterated function system. Specifically, considering the self-similarity and randomness of branch bifurcation structure, a corresponding pruning operation module is established. The visualization of the pruning of the branch morphology with higher degrees of freedom is implemented through the affine transformation matrix and geometric model producing more realistic computer simulation results. This paper provides guidance for the study and market selection of potted plants.
