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%。
China’s national flower - orchid is a genus of many different forms, so far no one has carried out its blooming simulation study. By studying phalaenopsis knowledge, several Orchid species with different morphological characteristics were used as virtual modeling objects to analyze their morphological characteristics. Then, a parameter transformation algorithm with random values based on organ model database was proposed, and an organ model database was established. Through appropriate transformation Orchid organs with different morphologies were obtained. According to the orchid growth pattern, different segmental parameters were used to control the growth of various organs. Through project practice, it was proved that this method could simulate the dynamic growth of orchids. At the same time joined the good interactive features, so that users can experience the different forms of orchids and placed in different scenes effect. Seven species of orchids were simulated by the system, with the system increasing sales by 10% at the show.
