| 摘 要： | 为了实现对苹果花及花序三维形态结构的交互设计、几何建模和真实感现实，提出了精确描述苹果花序三维形态结构的数学模型及可视化方法。通过对苹果花及花序形态结构的观测分析，分别提出了描述花柄、花托、花萼、花瓣、雄蕊和雌蕊三维形态结构的数学模型，并提取了模型的控制参数；进一步整合苹果花及花序的拓扑结构信息，实现了苹果花及花序的三维重建。为了增强花的真实感，提出了花柄、花托和花萼上绒毛的生成方法。结果表明，该方法可控性强，易于操作，可以精确重构出苹果花和花序的三维形态，实现对开花过程的可视化模拟，具有较强的真实感。 |

| Abstract: | Three-dimensional apple inflorescence modeling and visualization method is accurately proposed for the sake of achieving interactive designing, geometric modeling and reality realizing three-dimensional structure of apple flower and inflorescence. By observing and analyzing 3D structure of apple flower and inflorescence, we raised the 3D structure mathematical model of anthocaulus, receptacle, calyx, petal, androecium and pistil. At the same time, we get model parameter, integrate the apple flower and inflorescence topology structure information, reconstructed 3D structure of apple flower and inflorescence. In order to enhance the reality of the flower, we raised the generation approach of fine hair on anthocaulus, receptacle and calyx. The results indicate that this method is easy to control and prone to operate, it can reconstruct 3D structure of apple flower and inflorescence precisely and realize the visual simulation of flowering process with more realistic. |
