양은경(Yang, Eun Kyoung),김숙진(Kim, Sook Jin) 한국디지털디자인협의회 2014 디지털디자인학연구 Vol.14 No.1

3D 가상의상은 3D 가상착의 시뮬레이션 분야와 3D 캐릭터의 가상의상 분야로 나뉘고 두 분야는 서로 다른 기술을 사용한다. 그러므로 3D 가상착의 시뮬레이션을 이용하는 패션전공자가 3D 그래픽 소프트웨어의 전문지식을 요구하는 3D 캐릭터의 가상의상 분야에 접근하기는 쉽지 않다. 따라서 본 연구는 패션전공자들의 3D캐릭터 가상의상 제작 프로세스에 대한 이해를 증진시키기 위해 3D 캐릭터 가상의상 제작 소프트웨어를 소개하고 그 사용성을 분석하는데 목적을 둔다. 본 연구의 범위는 포저(Poser) 소프트웨어와 포저용 3D 캐릭터의 가상의상 콘텐츠 제작으로 한정한다. 본 연구의 방법과 내용은 1차로 3D 가상의상의 정의와 제작 소프트웨어들의 이론을 고찰하고 포저용 3D 캐릭터 가상의상의 특징과 제작 방법에 대해 정리한다. 2차로 독특한 패턴 디자인의 실제 원피스를 선정하여 디지털 클로딩 소프트웨어를 이용하여 3D 가상의상으로 제작하면서 그 표현 특성을 분석하였다. 3차로 포저를 이용하여 앞서 제작된 3D 가상의상을 포저용 3D 캐릭터의 가상의상으로 변환하는 프로세스를 살펴보았다. 이 과정에서 포저를 사용할 때의 장점과 문제점, 보완점 등을 분석하였다. 그 결과 포저는 인터페이스의 구성과 기능이 단순하고 소프트웨어 내에서 제공되는 제한된 3D 캐릭터 에디팅 툴을 이용하면 쉽게 3D 캐릭터의 가상의상을 제작할 수 있는 소프트웨어임을 확인할 수 있었다. 하지만 직물의 물성표현과 소재의 특성 표현에 있어 아직 미흡한 부분이 많아 후속연구가 기대되었다. 본 연구를 통해 패션업계와 학계에 많은 관심이 확대되길 기대하며, 이를 통해 패션산업의 활동 영역이 새로운 첨단으로 확대되길 바란다.

This study aims to examine for efficient production methods of custom-tailored clothing and application of 3D virtual clothing system in custom-tailored clothing market, by producing and analyzing both real clothing and 3D virtual clothing. For this study, a middle-aged woman is selected as the subject figure and one-piece is selected as the experimental clothes item. In real clothing, I conducted the wearing evaluation for experts and the subject figure. And In the virtual clothing, I conducted the wearing evaluation with i-Designer using 3D virtual clothing on simulation program. There are some differences between the data from body scanning and the real body size. In the custom-tailored clothing market in which the fitness is important, the research which measures the more exact data is needed. And in the case of complicate design, the functions which measure the activity and the fitness variously and correct the parts of curves are needed. This study experiments the availability of application of 3D Virtual Clothing System in custom-tailored clothing market by selecting one-piece as the experimental clothes item. So the follow-up studies for the other designs and fabrics are needed. Also, if the studies for checking the clothes pressure, the amount of composure, the space between skin and clothing when the virtual model wearing clothes is walking or shaking his arms are proceeding, then 3D virtual clothing System is applicable in custom-tailored clothing market. But there are some restrictions and lack of education in virtual clothing System yet, and it makes hard for workers in clothing market to use it in real production. However, 3D virtual clothing System will be practical in real market if there would be more research on its usability and practicality, and workers in clothing market can be easily educated on techniques of 3D virtual clothing system.

Hyeonah Kim,임호선 한국복식학회 2022 International journal of costume and fashion Vol.22 No.2

In order to expand the utilization range of 3D virtual clothing systems in the field of tight clothing, this study attempted to provide more in-depth research data to confirm the utility of CLO software in the field of tight-fitting clothing by comparing and evaluating the appearance similarity of 3D virtual clothing. In this study, the target outfit is selected as a basic short-sleeved top (Garment 1 without lining and subsidiary material), basic short-sleeved top with lining (Garment 2), chest cap (Garment 3), and chest cap (Garment 3-1) to determine the similarity among factors that may affect the appearance similarity of 3D virtual clothing. The costume pattern was digitized into YUKA CAD, the real fitting body was implemented in CLO through the 3D scan, and a 3D virtual image was produced. Then, Garments 1 to 3 were photographed and analyzed by evaluating the similarity between real and 3D virtual images on a 5-point scale to 10 experts. The results of this study are as follows. First, on evaluating the similarity between the real and 3D virtual images of Garments 1, 2, 3, and 3-1, the garments were seen that the implementation of lining insertion was similar and well-executed. There was no significant difference in the evaluation score of all garments to affect the usefulness of the CLO, although the difference between the evaluation scores of all garments was not significant, it was noted that the score of Garment 3 was the lowest, followed by Garment 3-1.

3차원 인체스캔형상을 재현한 3D 아바타 제작을 위한 가상착의 시스템의 활용성 검증 - CLO 3D 프로그램을 중심으로 -

홍은희 한국의상디자인학회 2020 한국의상디자인학회지 Vol.22 No.1

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.

본 연구의 목적은 3D 의상 CAD로 시뮬레이션 된 의복과 실물 제작된 의복과의 차이점을 비교 분석함으로써 현재 사용되고 있는 3D 의상 CAD 프로그램의 개선점 및 보완점을 밝히고자 하는데 있다. 사용된 소재는 신축성이 적은 면직물, 부드러우며 신축성 적고 광택이 있는 폴리에스테르 새틴 직물과 두껍고 거친 느낌이 나는 모직물이었으며, 이 세 가지 소재를 이용하여 3D 의상 CAD 프로그램(i-Designer)을 이용한 가상원피스와 실물원피스를 제작, 비교하였다. 본 연구의 결과는 다음과 같다. 1. 전체적인 실루엣 표현에서 3D 의상CAD로 제작된 의복과 실물 제작된 의복의 차이가 평균 4.00점 이상으로, 3D 의상CAD가 실물 제작 의복의 전체적인 실루엣을 표현하는 데는 무리가 없는 것으로 나타났다. 2. 가상의복을 실물의복과 비교한 결과 가장 실물과 유사하게 나타난 소재는 `모직물`소재로 나타났다. 3D 의상CAD로 제작된 의복과 실물 제작 의복의 차이가 앞면에서의 평균 3.86점, 뒤면 에서의 평균 3.75점에 비해 봉제선이 보이는 옆면의 평균은 3.53점으로 낮게 나와, 봉제선 부분의 표현력이 약간 부족하였다. 3. 3D 의상CAD 프로그램을 이용한 가상의복에서 원단의 물성은 제대로 표현되지 못하였다. The purpose of this study is to perform comparative analysis of differences between clothes simulated by 3D apparel CAD and actually-manufactured clothes to find out things to improve and complement in the 3D apparel CAD program. Cotton, polyester, wool were selected as comparative fabrics of the virtual one-piece dresses and actually-manufactured one-piece dresses. The results were as follows: 1. In expression of the general silhouette, the difference between clothes manufactured by 3D apparel CAD and actually-manufactured clothes was more than 4.00 on the average, 3D apparel CAD was found to have no difficulty in expressing the general silhouette of actually-manufactured clothes. 2. Among those three virtual clothes, woolen clothes was most similarly expressed to actually-manufactured clothes. Since the difference between clothes manufactured by 3D apparel CAD and actually-manufactured clothes was on the average 3.86 for the front part and 3.75 for the back part, as compared with 3.53 for the side part with needlework seen, it is necessary to improve expression at parts of needlework. 3. It was found that the virtual clothes using the 3D program could not express the physical properties of fabric.

Computerized Human Body Modeling and Work Motion-capturing in a 3-D Virtual Clothing Simulation System for Painting Work Clothes Development

( Gin Ah Park ) 한국패션비즈니스학회 2015 패션 비즈니스 Vol.19 No.3

By studying 3-D virtual human modeling, motion-capturing and clothing simulation for easier and safer work clothes development, this research aimed (1) to categorize heavy manufacturing work motions; (2) to generate a 3-D virtual male model and establish painting work motions within a 3-D virtual clothing simulation system through computerized body scanning and motion-capturing; and finally (3) to suggest simulated clothing images of painting work clothes developed based on virtual male avatar body measurements by implementing the work motions defined in the 3-D virtual clothing simulation system. For this, a male subject``s body was 3-D scanned and also directly measured. The procedures to edit a 3-D virtual model required the total body shape to be 3-D scanned into a digital format, which was revised using 3-D Studio MAX and Maya rendering tools. In addition, heavy industry workers`` work motions were observed and recorded by video camera at manufacturing sites and analyzed to categorize the painting work motions. This analysis resulted in 4 categories of motions: standing, bending, kneeling and walking. Besides, each work motion category was divided into more detailed motions according to sub-work posture factors: arm angle, arm direction, elbow bending angle, waist bending angle, waist bending direction and knee bending angle. Finally, the implementation of the painting work motions within the 3-D clothing simulation system presented the virtual painting work clothes images simulated in a dynamic mode.
