摘要
研究主要针对桃树生长的拓扑结构进行探讨,在分析桃树自然生长的基础上侧重探讨了人为因素的影响,针对人工修剪情况,运用基于双尺度自动机的模型方法建立了桃树生长的拓扑结构模型。模型中体现了分枝方式、分枝角度的变化。并针对模型中的节间生长变化进行了讨论,给出了节间变化的生长函数。同时,对比于L系统进行了分析。在二维仿真效果中,树体结构清晰,将真实的桃花植入,视觉效果较好,体现了花叶共生的特点。同时,二维仿真速度快,节省空间,数据测量方便。仿真结果表明拓扑结构模型符合桃树的生长规律,可为桃树的深入研究提供更直观的可视化支持。
The research mainly focused on the topology structure of peach tree. Natural growth and human factor have been involved together. Method of the dual scale automation has been used to modeling of topology structure for pruned trees. Change in branching style and branching angle has been shown in the model. At the same time,Growth function has been provided according to the change of internodes. And made comparisons between Dual scale automation and L- system. Structure of the tree is very clear,and the real peach blossom has been adopted at the 2D simulation. Characteristics of flower and leaves have been reflected. The model has fast simulation speed and less disk space. It is easy for measuring. The 2D result showed that the model accorded with growth rhythm and provided move intuitive support to the intensive study of peach tree.
