摘　　要：基于特征线的服装三维造型方法有诸多优点,但是现有服装模型并不能很好地支持服装参数化设计.为此将参数化造型方法引入三维服装部件造型中,以得到参数化的服装部件.基于光顺人体模型,依据服装部件特点设计服装特征线,将特征线分为截面环和轮廓线,依次通过截面环和轮廓线的生成与调整、特征线综合调整和特征线添加约束3个步骤,得到服装特征线框架;并对该框架利用曲面插值方法得到服装曲面模型.实例结果表明,文中方法功能强大、方便灵活.The method of 3D garment modeling based on feature curves has many advantages. However, current garment modeling methods cannot support parameterized design very well. This paper exploits a parameterization method for 3D garment components modeling to get parameterized objects. According to the characteristics of the garment components, the garment feature curves are determined according to human body. Feature curves include cross-section curves and contour curves. Through three sequential steps including generation and adjustment for the cross-section and contour curves, synthetical adjustment for feature curves and constraints appending, a garment feature frame is built. By applying surface interpolation on the feature frame, the garment surface model is ultimately constructed. The example results show that the modeling method based on feature curves is convenient and flexible.
