我国的国花——兰花类属繁多,形态各异,目前尚未有人对其进行花开仿真研究。通过研究兰花植物学知识,以几种不同形态特征的兰花为虚拟建模对象,分析其器官形态特点,提出基于器官模型库的带随机值参数变换算法,建立器官模型库,并通过适当的变换,得到形态各异的兰花器官,根据兰花生长规律,采用不同的分段参数控制各器官生长,通过项目实践,证明了此方法能逼真地模拟兰花动态生长。同时加入了良好的交互功能,使用户能体验兰花的不同形态及在不同场景中摆放的效果。系统对7种兰花进行了模拟,在展会中通过该系统,销售额增加了10%。As the national flower of China, orchid has various kinds of types and shapes, and its bloom process has never been simulated before.A model library of orchid organs was established and a transformation algorithm with random-valued parameters was proposed based on the model library of orchid organs by studying botanical knowledge of orchids and taking orchids with different morphological characteristics as research subjects for virtual modeling.Different segmental transformations were respectively performed on each organ of orchids to simulate growth of the organs according to the growth law of orchids.Different examples for simulating different type of orchids were provided to illustrate the realistic of dynamic growth of orchid by using the transformation algorithm.Meanwhile, the positive user interactive function of the simulation system enabled users to experience different orchids in different scenarios.Seven species of orchids were simulated in the system, and sales volume of orchids increased by 10% at the exhibition by using the system.福建省中青年教师教育科研项目(JB14210); 福建省科技重大专项(2013HZ0004-1
