Drape comparison between virtual fabric and real fabric for the production of virtual clothing

Abstract

Three-dimensional (3D) virtual garments imitate the silhouette and details of clothing in a virtual space on a computer without producing actual clothing and have been used in a variety of fields. As non-face-to-face services have become more popular in the fashion field, they are now being used for virtual models or digital fashion shows. As a result, the virtual garment must be similar to the real one. Drape is one of the factors that determines the silhouette of the garment. Thus, in this study, we compared the difference between real and virtual fabrics by using drape to confirm the similarity between the real and virtual fabrics. Fabrics were divided based on the fabric type and drape difference between the real and virtual fabrics. The experiment was carried out with the help of 287 woven and 318 knit fabrics. The drape ratio was used to test the drape quality of materials. By employing drape ratio, woven and knit fabrics were divided into seven grades, with eight fabrics selected for each grade. The drape ratio of the virtual and real fabrics was evaluated after creating virtual fabrics of selected fabrics using the CLO 3D application. Correlation analysis revealed that there is a correlation between the drape ratio of the real and virtual fabric for both woven and knit fabrics. However, t-test results demonstrate that there is a difference between the drape ratio of the real and virtual fabric, with the virtual fabric drape tending to be larger than the drape ratio of the real fabric. When fabrics were divided by type, the outer fabrics had the largest difference in drape between real and virtual. As drape property is affected by fabric functional processing, additional research is needed to determine what kind of functional processing affects the difference between real and virtual fabrics. In this study, physical and data were extracted from, and it is expected that this research can help contribute to the reproducibility of 3D modeling in the fashion field.
