摘要

提出了一种预测两片式罩杯纸模形状的方法。胸罩罩杯由几个布料部分(称为图案)和金属丝组成。图案的形状是通过反复制作由纸图案组成的杯子模型，然后检查其三维形状来设计的。为了减少这种试错过程，需要通过仿真来预测该模型的三维形状。由于模型是由纸制成的，所以每个部分都是不可扩展的，其变形表面是可展的。然后，图形的势能可以表示为其主曲率和主方向的函数。在几何约束下最小化势能，得到杯子模型的稳定形状。计算出的杯子形状与实际纸模型的测量形状几乎一致。特别地，预测了两种图案之间的连接线形状，平均位置误差为1.53 mm。

3D Shape Prediction of a Paper Model of a Brassiere Cup toward Its Design Support

A method to predict the shape of a paper model of a two piece brassiere cup is proposed. A brassiere cup consists of several cloth parts referred to as patterns, and wires. The shapes of patterns are designed by repeatedly making a cup model composed of paper patterns and then checking its 3D shape. To reduce such trial and error process, it is required to predict the 3D shape of such model with simulation. As a model is made of paper, each part is inextensible and its deformed surface is developable. Then, the potential energy of a pattern can be represented as a function of its principal curvature and principal direction. Minimizing the potential energy under geometric constraints derives the stable shape of the cup model. The computed shape of a cup almost coincided with the measured shape of an actual paper model. Especially, the shape of the joint line between two patterns was predicted with the average position error of 1.53 mm.
