中文摘要：
为模拟真实植物的具体外观形态,提出了一种植物形态结构表达模型。该模型从拓扑结构和几何结构两个角度对植物形态进行描述,将拓扑结构与归一化植物器官相结合构造形态结构。模型以叶元为描述植物形态结构的单位,保留了形态结构的细节信息,并用生长特征对形态结构进行归类,大大节省了植物模拟时所需数据量。选取松树的形态结构,使用模型对其进行模拟实验。结果验证了模型的可行性和有效性。模型能够用于自然景观模拟、植物可视化、计算机辅助设计等领域。
英文摘要：
In order to simulate the morphology structure of plant,a plant morphological structure model is proposed.The plant morphological structure is described from two aspects：Topological structure and geometrical structure.Geometrical structure is constructed by topological structure and normalized plant organs.Metamer is used as the unit for describing the morphological structure of plant,which helps keep the structure details.Growth characteristic is chosen as the standard to classify the characters of plant morphological structure,so that the simulation data required for modeling plant morphological structure can be compressed.This model is tested by the simulation of a pine tree,which demonstrates the effectiveness and feasibility of the model.The plant morphological structure model can be applied to natural scenery simulation,plant visualization,computer-aided design,and so on.
