  • The purpose of this study is to testify the pattern making method to develop the men's basic bodice pattern using 3-dimensional body scan data. The experimental patterns were made by adding wearing ease on flattened body scan data and tracing the outlines of it. The experimental bodice pattern were composed of front, back, and side panels. To compare the difference between the experimental pattern and traditional pattern, two pattern making methods were compared. Two sets of basic bodice patterns were made for each of the 10 male subjects: a set of pattern was made by experimental method and the other set was made by Bunka pattern making method. The experimental and traditional patterns were measured at 13 dimensions. The results show that there was a difference between the experimental patterns and traditional patterns at the front length, back length, front width, front neck width, back neck width, and back neck depth. The fit was also compared for both patterns. The results of the fit test show that the experimental patterns were superior to the traditional patterns at the fit of neck, shoulder, and armhole. The experimental pattern making method was expected to be useful for mass customization.

  • This study was conducted in order to spread out lower body 3D scan data of men in their twenties. The aim was to achieve slacks pattern with ease allowance through comparison with existing flat patterns. For conversion of 3D scan data into 20 pattern, reference lines were established by using Rapid Foam in 3D shape analysis software. 2C-AN program and Yuka CAD were used to convert 20 pattern earned with straight posture of 3D scan data into slacks pattern by using Triangle Simplification & Runge-Kutta Method. In order to achieve this we needed to set a line 9cm below the hip line, to array vertex of each block to crease line while maintaining the horizontal line. And then we needed to set ease allowance in back crotch and to set waist circumference or hip circumference ease allowance in side seam of slacks. Results showed that long front crotch length can be achieved if 3D scan data is compared with 20 existing flat pattern. Slacks pattern that raise front crotch by about 1.5cm compared to back crotch and also possess ease allowance in back crotch area are great in appearance evaluation.

  • This study analyzes the foot shape of female high school students using 3D foot scan data based on a comparison with adult women (20s'-30s'). Data were collected from the foot anthropometry of 199 female high school students in Gwangju and Jeollanam-do. The right foot was measured indirectly by 3D laser scanner. There are 16 items in the foot anthropometric measurements. The $6^{th}$ Size Korea (measured by 3D scan data) is used for women's foot data. The results of the 3D measurements data investigation show that the foot length and foot width became longer and wider as the age increased. It is classified by three types after analyzing foot shape. Type 1 (28.1%) represented the shortest foot length, the narrowest foot width as well as the thick foot and long ankle shape. Type 2 (4.3%) represented the wide foot width such as the wide lateral ball width and semi-thickness shape. Type 3 (67.7%) referred to the widest foot width, flat foot and short ankle shape.

  • Adjusting pressure level in the construction of athletes' tight-fitting garments by reducing the elastic knit pattern is a challenging subject, which influences the performance of the wearer directly. Therefore, in this study, relationship between the reduction rates of the basic pattern obtained from 3D human scan data and resultant clothing pressure was explored to improve the fit and pressure exerted by clothing. 3D scan data were obtained using Cyberware and they were transformed into a flat pattern using software based on Runge-Kutta method. Reduction rate was examined by subjective wear test as well as objective pressure measurement. As a result, difference in the length between the original 3D body scan data and the 2D tight-fitting pattern was 0.02$\sim$0.50cm (0.05$\sim$1.06%), which was within the range of tolerable limits in making clothes. Among the five garments, the 3T-pattern was superior in terms of subjective sensation and fit. The pressure of the 3T pattern was 2$\sim$4 gf/cm2 at five locations on the body, which is almost the same or a bit higher than that of Z-pattern. In the case of tight-fitting overall garment, the reduction rate of the pattern in the wale direction is more critical to the subjective sensation than the course direction. It is recommended that the reduction grading rules of course direction should be larger than that of Ziegert for a better fit of tight-fitting garments. In the case of wale direction, however, reduction grading rule should be kept the same as suggested earlier by Ziegert (1988).

  • The purpose of this study is to provide fundamental information for standardization of 3D body measurement. This research analyzes errors occurring in the process of extracting body size from 3D body scan data. First, as a result of analyzing basic state of the 3D body scanner's calibration, the point number of each section was almost the same, while the right and left as well as the front and back coordinates of the center of gravity are not, showing unstable data. Nevertheless, the latter does not influence on the size of cylinder such as width and circumference. Next, we analyzed point coordinates variations of scan data on a mannequin nude by life casting. The result was great deflection in case of complicated or horizontal sections including the reference point beyond proper distance from centers of four cameras. In case of the mannequin's size, accuracy proves comparatively high in that measurement errors in height, width, depth, and length dimension occurred all within allowable errors, only except chest depth, while there were a lot of measurement errors in a circumference dimension. Secondly, analysis of accuracy of automatic extraction identification program algorithm presented that a semi-automatic measurement program is better than an automatic measurement program. While both of them ate very acute in parts related to crotch, they are not in armpit related parts. Therefore, in extracting of human body size from 3D scan data, what really matters seems to parts related to armpits.

  • The purpose of this study was to develop the pattern of scuba diving suits for local men in their thirties by using 3D body-scanned data. It is widely acknowledged that draping method is more suitable than flat pattern for body shape as most scuba diving suits in the market are designed to fit the body tightly in a single piece with sleeves and legs. A dummy for this study was made based on men's standard clothing sizes in 30's which was derived from data of 2004 Size Korea. Accordingly, the basic body block was built upon through draping method. Next, a scuba diving suit was made from neoprene, followed by fit and the clothing pressure tests in order to evaluate the diving suit's functionality and comfort. The results of the fit test had high points of 4.33 in majority parts except armhole and crotch ones. In comparison of clothing pressure between wearer and dummy, the clothing pressure of wearer was indicated relatively low in most parts other than armhole and knee, resulting from cushion function of skin and muscle and high stretch of fabric.

  • This study aims to analyze middle-aged men's frontal body shape asymmetry by measuring the left and right body dimensions and angles of 388 middle-aged men aged 40 to 59 using 3D body scan data and comparing the measured values. The study also compares the measured values of width, height, and angle and their relationships using Size Korea's anthropometric measurement and posture index of the New York Posture Rating Scale. The results confirm that the asymmetric shape characteristics of the upper and lower body appear differently. In addition, the asymmetrical characteristics between the upper and lower body differed, indicating that the close parts of the body affect each other. Similar to the difference in the left and right frontal body shapes and the average angle distribution, the asymmetrical upper and lower body characteristics also are found to be dissimilar when the correlations are examined. In contrast, there is no asymmetry in the width, height, and angle considering the age and BMI groups. Finally, the study classifies three body types and identifies their asymmetric characteristics. Overall, this study contributes primary data for further research on pattern production for asymmetric and unique body types and the development of customized apparel products.

  • There still is a limitation in the usage of 3D clothes model in the production line due to the lack of compatibility between 3D modeling software, and its accurate 2D pattern making software, especially for free formed dress with tight fitted zone and draped part. In this study, obstacles in the 3D direct dress design process was overcome by solving the compatibility among each step of 3D virtual design process as well as adopting 3D-2D direct pattern development program called 2C-AN. Efficacy of making 2D pattern from 3D dress design using 2C-AN program developed by the authors was examined during the course of actual dress making process. Accurate ease over the fitted dress part was examined by 3D scanning technology, and the actual appearance of the draped part was compared with the simulation image of dress model. It was confirmed that the entire 3D design process and direct 2D pattern development proposed in this study was accurate enough to use in the 3D design process.
