基于重瓣花朵拓扑结构模型算法的可视化研究

针对重瓣花朵结构较为复杂、花瓣排列方式非线性较强、三维模拟效果较差的问题,提出了一种重瓣花朵拓扑结构模型算法。以牡丹作为实例,根据植物学中花瓣排列方式理论,加入随机扰动函数,通过扩展的L系统构建出不同层次的花朵形态模型,采用双三次Bezier曲面来构造花瓣模型,运用基于三角形面片模型的二维纹理贴图方法,可完成任意层次的花朵建模。该方法简单直观,并且真实感效果较好。

Visual Analysis of Double Flowers Topology Structure Model Algorithm

Aiming at the problems that double flowers structure is relatively complex, and petals arrangement of the nonlinear is stronger, and the three dimensional simulation effect is poor, this paper put forward a double flowers topology structure model algorithm. Using peony as examples, according to the arrangement of botany petals theory,joining the randomized function, expanding the L system to construct different levels flowers form model, using two I3ezier surfaces three times to construct the petals model, using 2 d texture mapping method based on triangle strips of model, the algorithm can complete any level of flowers modeling. This method is simple, intuitive, and the reality sense effect is good.
