A New Three-Dimensional Design System for Foundation Garment

女性基础服装的设计不仅应基于对体型的精确测量，还应基于对其贴合体表的分析评估。建立了乳房形态的三维设计系统，实现了乳房形态的测量和建模、乳房特征的分析、乳房形态的模拟、乳罩纸样的开发以及乳房穿戴舒适性的感官评价，采用双曲线三维B-样条法进行乳房造型。为了分析评价乳房的特征，计算了一致性指数和振型。得出了穿着舒适性与服装压力的关系，为文胸的感官评价提供了依据。新的计算机辅助系统被发现非常有用，因为它对人体形态变化具有良好的3D可视化和分析性能，对于设计女性的紧身衣非常有用。

Foundation garments for females should be designed based on not only precise measurement of the body shape but also analytical evaluation of their fitting to the body surface. We created a three-dimensional (3D) designing system, which facilitated measurement and modeling of the breast shape, analysis of breast characteristics with and without brassieres, simulation of the breast shape wearing brassieres, supporting paper pattern development of brassieres, and sensory evaluation of wearing comfort of brassieres.Modeling of the breast shape was performed using a hyperbolic 3D B-spline method. The consistency index and vibration patterns were calculated for analytical evaluation of characteristics of the breast. The relationship between wearing comfort and clothing pressure was obtained for sensory evaluation of brassieres. The new computer-aided system was found to be very useful for designing foundation garments for females because of the good 3D visualization and analytical performance on morphological changes of the human body.
