摘要： 针对荠菜根系的形态特征和生长特点，提出一种基于几何模型的荠菜根系三维建模方法：根据荠菜根系的拓扑几何结构，应用根系几何模型SimRoot，基于Visual C++平台并采用OpenGL图形库，建立能较真实再现荠菜根系动态生长过程的可视化模拟系统。模拟结果表明该方法是可行有效的。

Abstract: According to the morphological character and growth feature of shepherd’s purse root system, a 3D modelling method based on the geometrical modelling is proposed. Topological and geometrical structure of shepherd’s purse root system is employed. SimRoot, a geometrical modelling of root systems, is applied. Graphics library OpenGL on the Visual C++ platform is used to establish a visual simulation system which can vividly simulate the growing process of shepherd’s purse root system. The simulation result shows that the proposed method is of validity and feasibility.

Key words: shepherd’s purse root system, geometrical model, geometrical structure, simulation
