基于交互的花卉建模方法

Flowers Modeling Based on Interactive Method

针对现有的花朵建模方法大多存在算法复杂、计算量大、人工干预多、技术要求高的缺点,提出一种基于交互的花卉建模方法。该方法从点入手,首先根据手绘花瓣的轮廓图得到花瓣模型的二维控制点,然后通过弯曲控制函数得到花瓣模型的三维控制点,再利用三维控制点构造三维花瓣模型,最后由多个花瓣构建花朵并对其进行真实感渲染。实验表明,该建模方法无需使用复杂的建模技巧且生成的花瓣具有较强的真实感。

Against the defect that the existing modeling method of flowermostly have much weakness for their complicated algorithm, lardecalculation, too much manual intervention and high demand of techniques, presents a modeling method of flower which is based on sketching the petal.This method conducts from the original point. At first,it extracts the two-dimensional control points based on the profile curve of sketching petal. Then, it receives the three-dimensional control points using bending control function, and constructs 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 result shows that, without using complicated modeling skills but these flowers have better sense of reality.
