Surface shape features of 3D tight-fitting skirts using angle curvatures in virtual reality

Abstract

This study examined the significant factors involved in a custom-made garment creation system used for 3D fitting and 2D patterns for skirts. 3D tight-fitting skirts were developed from 3D imaginary skirt forms simulated by constructing individual 3D body shapes using a convex hull. The features of the 3D curved tight-fitting skirt surface shapes of 1,044 females were extracted by means of the angle curvatures of the triangle mesh 3D skirt shapes to yield information that can support communication between retailers and their consumers. There are deficit angles of concentrated Gaussian curvature Kc on interior area vertexes and concentrated geodesic curvature kc on the exterior boundary waistline and hemline vertexes. We identified the features of the 3D tight-fitting skirt curved surface shape, including the presence of darts, for a considerable number of female for 2D pattern generation, regardless of the body size and without using cloth or having to sew a skirt. We then classified the 3D tight-fitting skirt curved surface shapes based on the features of the areas, including the female ages. A viable virtual reality custom-made tight-fitting skirt creation system was established to support the development of an eco-clothing lifestyle and to provide the information needed for the project to succeed.
