摘要:: 目前对阿尔泰金莲花的研究主要集中在药理性方面,在三维可视化模拟方面的研究尚处于空白.文中通过提取阿尔泰金莲花各器官形态特征参数,基于图像造型方法构建叶片,基于贝塞尔曲面方法构建花萼和花瓣,基于多边形变形方法构建花蕊和茎.以Qt为平台、OpenGL为图形库、MYSQL为数据库,应用参数L系统来表现阿尔泰金莲花的拓扑结构,并结合各器官的几何模型实现了阿尔泰金莲花三维可视化模拟.同时利用Assimp模型加载库实现模型的导入导出功能,使系统具有更好的兼容性.实验结果证明,该方法能够较为真实地展示阿尔泰金莲花的形态结构以及动态生长过程,并为阿尔泰金莲花的深入研究提供借鉴.

Abstract:: At present,the research on Trollius Altaicus is mainly focused on the aspect of pharmacology,but there is no research on the three-dimensional visual simulation. Therefore,we extract Trollius Altaicus organ features and then use the image modeling method to build leaves,with Bezier surface method to build calyx and petals and polygon morphing method to build stamens and stems. Taking Qt as platform,OpenGL as graphics library and MYSQL as database,the topological structure of the Trollius Altaicus is displayed based on the L system,then the 3D visual simulation of Trollius Altaicus is implemented combined with the geometric model of the organs. Meanwhile,the Assimp model loading library is used to realize the import and export function,which makes the system has better compatibility. The experiment shows that the proposed method can truly display the structure and dynamic growth of Trollius Altaicus and provide reference for further research of Trollius Altaicus.
