  • An integrated platform for garment drape simulation system has been developed. In this system, garment patterns from conventional two-dimensional CAD systems can be assembled into a three-dimensional garment on a parametrically resizable realistic human body model. A fast and robust particle-based physical calculation engine has been developed for garment shape generation. Then a series of geometric and graphical techniques were applied to create realistic impressions on simulated garments. This system can be used as the rapid prototyping tool for garments in the future quick-response system.

  • A simulation system for versatile garment drape has been developed. Using this system, the shape of a garment can be simulated in consideration of fabric physical properties as well as the interaction between fabrics and other objects. Each fabric piece in a garment is modeled using a geometrically constrained particle system and its behavior is calculated from an implicit numerical integration algorithm in a relatively short time. The system consists of three modules including a preprocessor for the preparation of fabric patterns and external objects, a postprocessor for the results of three-dimensional visualization, and a drape simulation engine. It can be used for the design process of textile goods, garments, furniture, or upholsteries.

  • A web-based custom garment design system was developed that enables users to design their own garment by placing various images and texts on three-dimensional (3D) garment models generating the image data for digital textile printing (DTP). An image mapping software was developed to test the mapping of images and texts on 3D garment models. Garment models were prepared by specially designed drape simulation software that provides DTP-ready pattern data along with the garment models. A common gateway interface (CGI) software module and a test server were developed using the core of the image mapping software. Users can design various customized garments in 3D using this CGI software on any device type or operating system as long as they have access to the Internet. Finally, the designed garment is converted into a single image that can be directly used for DTP garment production.

  • Advances in 3D garment simulation technology contribute greatly to consumers becoming more immersed in movies and games by realistically expressing the garments the characters in the movie or game are wearing. The fashion industry has reached a point where it needs to maximize efficiency in production and distribution to go beyond time and space in order to compete on the global market. The processes of design and product development in the fashion industry require countless hours of work and consume vast resources in terms of materials and energy to repeat sample production and assessment. Therefore, the design and product development tools and techniques must aim to reduce the sample making process. Therefore, this study aims to study a case for comparing the real garment sample making process to the virtual garment sample making process. In this study, we have analysed the differences between the real and virtual garment making processes by choosing designated patterns. As we can see from the study results, the real and virtual garments generally are made through similar processes in manufacturing, while the time consumed for each shows great variation. In real garment making, scissoring and sewing require the greatest number of work hours, whereas in virtual garment making, most of the time was spent in the simulation process.

  • A study using 3D virtual garment simulation is carried out for the evaluation and application on the pants fit for obese women in their age of 20s and 30s. The results are as follows; 5 obese women in their 20s and 30s were selected for the testing 3D body. They showed no significant differences in all items, comparing with the data of 5th Size Korea body dimensions. The average waist circumstance of the subjects' 3D body dimensions was 87.0cm, hip circumstance was 102.4cm, BMI was $27.1kg/m^2$, and their obese body types had similar mean values. Based on the detailed design of ready made pants and the study results of 20~30s obese women preference for pants design, pants of straight silhouette and semi-tight fit which have waist line lowered, no front dart and one back dart, were manufactured with 100% black cotton and cotton spandex mixed fabrics. When comparing the appearances between real garment and virtual garment, the average of the real garment with 100% cotton was 3.70 and the virtual garment was 4.05. The average of real garment with cotton spandex mixed fabrics was 3.75 and the virtual garment was 4.06. Therefore, the average of virtual garment was highly evaluated. When comparing the results of evaluating the appearance, there was no significant difference caused by materials between real garment and virtual garment. The expression for the ease of virtual garment and real garment was also similar for good evaluation. Thus, 3D virtual garment simulation did positively prove its reliability and effect.

  • This study investigated garment formability of the 73 breathable fabrics for sports-wear garment and their fabric mechanical properties were measured using KES-FB and FAST systems. Predicted garment formability from the mechanical properties measured using KES-FB and FAST systems was compared and discussed with fabric structural parameters. In addition, virtual 3D simulation silhouette by I-designer CAD system wear appearance by simulation using 3D CAD system. And compared with FAST finger chart by mechanical properties of FAST system. The correlation coefficients of extensibility and shear modulus between KES-FB and FAST systems were high, however, bending rigidity and compressibility showed relatively low correlation coefficients. The correlation coefficient of garment formability of breathable fabrics between KES-FB and FAST systems was 0.82. It revealed that garment formability can be predicted from fabric mechanical properties by KES-FB and FAST systems. The garment formability of nylon breathable fabric was higher than that of PET one, and the garment formability of laminated breathable fabric showed the highest value compared to coated, dot and hot melt laminated breathable fabrics. It revealed that garment formability of breathable fabrics for sports-wear can be predicted from fabric mechanical properties and garment formability was dependent on the materials, finishing method and fabric structural parameters.

  • The purpose of this research is to compare and analyze visual images between the Real garment and the 3D garment simulation with the various fabrics of flare skirts and to analyze the correlation between mechanical properties and visual images. The picture images (printed on paper) of the Real garment and the 3D garment simulation of experimental flare skirts were shown to the evaluation group of women in their 20s majoring in clothing and textiles, and were evaluated by questionnaires with 32 adjectives. SPSS Version 12.0 statistics program was utilized to analyze data. Factor analysis, One Way ANOVA, T-test and Duncan test were used to investigate visual effect of the Real garment and the 3D garment simulation. As the result of conducting factor analysis on the visual appearance, the images were driven with five factors: 'drapeability', 'attractive', 'body compensation', 'bulkiness', 'activeness'. Visual images were significantly related with mechanical properties of various fabrics, and the visual images between 3D garment simulations and real garment differed with various fabrics and their mechanical properties. Visual images of silk and polyester group, cotton, linen and wool group were significantly related with weight and thickness of kinds of fabrics.
