We try to design the clothing pattern of each individual body type for young men using a computer program that we created for this purpose. In our study, we examined clothing-pattern making from the point of view of two factors : "angle" and "line length" of the 3D torso surface and the tight-fitting bodice. The central problem of the pattern-making is to create a three-dimensional body. Therefore, we investigated the deficiency factor on both a two-dimensional developed pattern on 3D bodies. On the developed pattern, we studied it as 'deficit angles', while on 3D bodies, it appeared as 'gap length' on the pattern measurement lines.At first, for a clear understanding of male 3D surface, we compared the torso shape of females (n = 203) and males (n = 101) using the Concentrated Gaussian Curvature Kc (deficit angle = 2π-θ) of the vertices on interior triangle-meshed surface and Concentrated Geodesic Curvature Kc (π-θ) on the vertices of exterior boundary lines. If Kc of an arbitrary poin … More t (vertex) on a surface is equal to zero, the surface may be said to be a plane and developable one. On a curved surface, Kc is not zero. The sum of two integrated values, Kc of the inside surface shape and kc on the boundary curve, is equal to the multiplied value of 2π and the Euler number. The sum of those two curvatures in the torso surface of each female (n=203) and of each male (n=101) was the same value (-2 × 2π). Due to this, we were able to compare the torso shapes between males and females, regardless of size. The main features of the male torso shape are the back, shoulder, and side surface, and that of the female torso shapes is the bust surface. Although the male torso has a developable surface, the main features differ considerably between each person. Therefore, it is necessary to use high level techniques and technology for male pattern-making. One method for 3D pattern-making, without the draping, is using a computer programmed with the convex method to automatically design 3D bodice patterns which would cover the male torsos (n = 150). We call that 3D bodice the 'convex hull bodices', and examined them using Kc, kc, and Mean Curvature Hc, which refers to be convex or concave surfaces. The Kc values of the convex hull bodices are smaller than those of the torsos, therefore their kc values are large. As with the Kc values, the Hc values are also smaller than those of the torsos. The 3 curvature values of the convex hull bodices are classified using the principal component analysis by correlation. In addition, the combination factors of six areas and three lines were classified. We were able to easily construct a tight-fitting bodice using a computer program to do 3D draping. The system aided us visually understand features of the surface shape through color-graded map displaying curvatures and gap values (volume).Next, we examined the features of the tight-fitting pattern (T-pattern) of females (n = 203) and males (n = 151) using the gap length and Kc values. The factors for making the T-pattern shape were found using the classing the principal component anarisis of the Kc values. Like the above 3D draping technique, drafting pattern-making using the estimated gap lengths may also be finished with aid a computer.As the result of the two examinations using the "angle" and the "line length" on both of the 3D torso surface and the tight-fitting bodice, we are able to take the automatically pattern-making for both the 3D draping and the drafting according to the types of the body shape.

我们尝试使用为此目的创建的计算机程序来设计每种体型的服装图案。在我们的研究中，我们从两个因素的角度检查了服装模式：3D躯干表面的“角”和“线长度”和紧身的紧身胸衣。图案制作的核心问题是创建一个三维的身体。因此，我们研究了3D主体上二维开发模式的缺陷因子。在开发的模式上，我们将其研究为“赤字角度”，而在3D身体上，它在模式测量线上似乎是“间隙长度”。首先，在清楚地了解男性3D表面，我们比较了女性（n = 203）和雄性（n = 101）的躯干形状（n = 101），使用浓缩的高斯曲线（n = 101），相互弯曲的角度（n = 101）nefien conterior tre tremern tremertior tre tre tre tre tre tre tre-verior trot =2π-2π-均=2π-均与2-prient =2π-相互作用=2π-外部边界线顶点上的浓缩地球曲率KC（π-θ）。如果一个任意点的kc……表面上的更多t（顶点）等于零，则表面可以说是平面并开发的平面。在弯曲的表面上，KC不为零。边界曲线上两个积分值的总和kc的总和等于2π的乘以值和欧拉数。每个雌性（n = 203）和每个雄性（n = 101）的躯干表面的这两个曲率的总和是相同的值（-2×2π）。因此，我们能够比较男性和女性之间的躯干形状，无论大小如何。雄性躯干形状的主要特征是背面，肩膀和侧面，雌性躯干形状的表面是胸围。尽管雄性躯干具有可开发的表面，但每个人之间的主要特征都不同。因此，有必要将高级技术和技术用于男性模式。 3D图案制作的一种方法，没有悬垂，是使用使用凸方法编程的计算机来自动设计覆盖雄性躯干的3D紧身胸衣图案（n = 150）。我们称3D紧身胸衣为“凸壳体”，并使用KC，KC和平均曲率HC检查了它们，该曲率是指凸或凹面表面。凸壳体的Kc值小于躯干的KC值，因此它们的KC值很大。与KC值一样，HC值也小于Torsos的值。凸壳体的3个曲率值使用主组件分析通过相关进行分类。此外，分类了六个区域和三条线的组合因子。我们能够使用计算机程序轻松构建紧身紧身胸衣进行3D悬垂。该系统通过显示曲线和间隙值（音量）的颜色分级地图在视觉上了解表面形状的特征。我们检查了女性（n = 203）和男性（n = 151）的紧身贴合图案（t-pattern）的特征，并使用差距长度和kc值。使用分类的KC值的主要成分解剖学发现了制作T-Pattern形状的因素。 Like the above 3D draping technique, drafting pattern-making using the estimated gap lengths may also be finished with aid a computer.As the result of the two examinations using the "angle" and the "line length" on both of the 3D torso surface and the tight-fitting bodice, we are able to take the automatically pattern-making for both the 3D draping and the drafting according to the types of the body shape.较少的
