竹子地下茎-根的计算机仿真

Computer Simulation of Underground Stem-root of Bamboo

针对竹子地下茎-根的形态特征和生长特点,提出一种基于几何构造模型的竹子地下茎-根三维建模方法。该方法建立竹子地下茎-根的拓扑结构和几何结构,通过"渲染"处理其三维几何结构。结合该技术在Visual C++环境下,通过递归的算法思想和程序编制,建立一个能够较真实地再现竹子地下茎-根动态生长过程的计算机仿真系统。仿真结果表明了该方法的可行性和有效性。

According to the structure and growing characteristic of underground stem-root of bamboo, a 3D modeling method based on the geometrical modelling is proposed. In this way, topology and geometrical structure of underground stem-root of bamboo are built, then the 3D geometrical structure of underground stem-roots of bamboo is dealed with by ＇Rendering＇. Combined with this technique, using recursive algorithm and programming in the Visual C＋＋, a system, which can simulate the growing process of underground stem-root of bamboo with verisimilitude, is established. Results prove that the proposed method is of good validity and feasibility.
