This study investigated similarities and differences between 2D flat sketch, 3D virtual clothing and real clothing images. Flat sketch, 3D virtual clothing, and real clothing images of T-shirts and dresses were made. Questionnaires were prepared for fit evaluation, sensory evaluation, and location evaluation. A survey of 440 questionnaires was collected from Chinese women in their 20s and 30s. As results of the sensibility evaluation, 3D virtual clothing expressed real clothing images slightly more similar than a 2D flat sketch. As results of the fit evaluation of the dresses, 2D flat sketch and 3D virtual clothing were rated as slightly longer/wider, and real clothing images were rated as slightly shorter/narrower. The results suggested that presenting 3D images with avatars as 3D virtual clothing images will provide more accurate fit evaluation results. This study presented possibilities and methods for apparel companies to utilize 3D system as an effective apparel production tool.

This study comprehensively analyzes previous research comparing the similarities between 3D virtual and actual fittings, and identifies the current usage and limitations of virtual fitting programs. The findings reveal that, in most cases, 3D virtual fittings are not perfect substitutes for actual fittings. To address these limitations, this research focuses on the Hohenstein fitting test and BP-ANNs-based garment fit evaluation method, which incorporate various parameters, such as the correlation between wearers and garments, garment pressure, and ease, thus providing objective data, such as data acquired that can enhance subjective evaluations. By integrating such objective assessments, the study suggests potential improvements in virtual fitting accuracy. This research is expected to provide foundational data necessary for the development of a consumer virtual fitting systems alongside advancements in 3D virtual fitting technology.

본 연구에서는 PC상에서 인체 3차원 데이터에 상하의 의류를 중첩 착의하는 가상 착의 시스템을 소개한다. 이를 위하여, 레이저 스캔 방식으로 얻은 인체 3차원 데이터와 의류 앞뒷면의 모습을 촬영하여 얻은 의류 디지털 데이터를 이용한다. 2차원의 앞뒷면 의류 디지털 데이터에는 의류 소재 내 질점 간의 장력이 반영되었고, 인체 데이터에의 착의 과정에는 마찰력과 중력을 적용해 주었다. 하의 착용 시에는 마찰력과 중력에 추가적으로 혁대 개념을 도입하여 흘러내리는 의류를 고정하였고, 하의를 착의한 인체데이터위에 상의를 착의하는 중첩 착의 방법을 제시하였다. 본 시스템이 지닌 장점은 복잡한 패턴을 이용하여 착의하는 다른 연구와 달리, 의류의 앞뒷면만을 이용하여 착의하면서도 현실감은 뒤지지 않는다는 것에 있다. 현재 의류전자상거래 시 의류의 앞뒷면만을 전시하여 판매하는 방법과 유사한 방식으로 온라인 판매가 이루어지나, 착의 모습을 제공할 수 없는 기존 방식과 달리 3차원의 착의 모습까지 제공하게 되어, 의류 판매의 방식을 바꾸게 할 것으로 기대한다.

The purpose of this study is to create a 3D avatar from 3D human body shape data using the CLO 3D virtual clothing program and to verify the feasibility of avatar production using the virtual clothing system for verifying size and shape. The research method was to select one virtual representative model that is the closest to the mean size of each body item for each age group. Using the 3D human body scan shape of a 40-69 years old male was applied to the CLO 3D virtual wearing system. Using the CLO 3D Avatar conversion menu, we verified the feasibility of creating a 3D avatar that reproduces the human body scan shape. In the dimension comparison between the 3D avatar and the fictitious representative model, the dimension difference was noticeable in height, circumference, and length. However, as a result, the converted 3D avatar showed less than a 5% difference in most human dimensions. In addition, since the body shape and posture were reproduced similarly, the utilization of the avatar was verified.

This study aims to verify the sewing technology and the expression of the virtual garment program by comparing the appearance similarity between the real and the virtual power shoulder jacket. To this end, the H and the X silhouettes of the power shoulder jacket were selected as the reference designs. After making the reference designs into real jackets by applying the human body dimensions of women in their twenties, virtual avatars and jackets were produced using CLO 3D programs. The results showed that the H-type with only expanded shoulders and less design variation had a high similarity between the reference photo and real garment, the real and virtual garment, and the reference photo and virtual garment. The power shoulder jacket of the reference picture was well reproduced in the real and virtual garments. Conversely, the X-type jacket, which is a tight fit and has many design variations, showed somewhat low similarity in the circumference items and the basic construction line. Especially in tight-fitted power shoulder jackets, the fact that shoulder angles and the essential items for pattern making cannot be reflected in reproducing virtual models was found to be a limitation in increasing the similarity of virtual clothing. Furthermore, the sewing system gap between the real and the virtual clothing exposed a difference in the appearance of virtual clothing.

This study analyzed the difference between 2D image and 3D virtual clothing images based on stripe arrangement to obtain fundamental data for slim appearance. First, the slimming effect according to the three types of stripe ratio was examined. Subsequently, the slimming effects of seven types of one-piece dress designs according to the stripe location were analyzed. Subjective ranking was evaluated. The width items and radius of curvature were measured for the image's respective parts. Consequently, in 2D image and 3D virtual clothing images, the one with the narrowest stripe ratio was evaluated as the slimmest; however, the conditions for the slimming effect were different. In the seven one-piece dress designs, a difference was apparent in the ranking of the 2D image and 3D virtual clothing images. In the 3D virtual clothing image, arranging the stripes on the entire garment proved inefficient. The stripes were curved according to the curvature of the human body, creating an optical illusion that differed from that of the 2D image.

The purpose of this study was to analyze the three-dimensional (3D) characteristics and reproducibility of the effective expression of North American smocking pleats in the process of making clothes using a 3D virtual clothing system (CLO) and present a method of expression according to the types of North American smocking. In this study, lattice, lozenge, and flower smocking were produced as real smocking and 3D virtual content, and actual muslin properties were measured using a Fabric Kit and reflected using an emulator. The results of this study confirmed that a dense puckered design such as North American smocking could be expressed depending upon the internal line, fold angle, and reinforcement setting for 3D smocking. To partially apply pleats to flat fabrics, it was necessary to set fold lines. The fold line setting could be expressed by designing the internal line in horizontal, vertical, and diagonal directions according to the North American smocking design, and then setting the fold angle for each internal line. By setting fold angles of 0 degrees and 360 degrees according to the folding direction of the set internal line, the fabric was clearly folded and stable pleats were created. This study will contribute to the vitalization of the 3D virtual fashion content industry by analyzing and presenting the optimal expression method of sophisticated and complex pleats generated according to the North American smocking design pattern.
