基于手绘花瓣的花朵建模方法

Modeling method of flower based on sketching petal

针对现有花朵建模方法形成的花瓣式样与形态单一的缺陷,提出一种基于手绘花瓣的交互式花朵建模方法。该方法首先根据手绘花瓣的轮廓图提取花瓣模型的二维控制点,然后通过弯曲控制函数得到花瓣的三维控制点,继而利用三维控制点构造三维花瓣模型,最后由经过真实感渲染的单个花瓣构建花朵。实验结果表明,与其他建模方法相比,该建模方法能够方便地生成各种裂瓣状花瓣的花朵且真实感更强。

Against the defect that the existing modeling method of flower could only form the petal with single pattern,this paper presented a modeling method of flower which was based on sketching the petal.At first,it extracted the two-dimensional control points based on the profile curve of sketching petal.Then,it received the three-dimensional control points using bending control function,and constructed the three-dimensional model of petal using these three-dimensional control points.At last,after photorealistic rendering the single petal,the flower could be gotten.The experimental results show that,comparing to the other modeling methods,this method can expediently generate kinds of flowers with crack-like petals,and these flowers have better sense of reality.
