3D 의상 CAD 시스템을 이용한 가상의복에 관한 연구

Abstract

The aim of this study lies in realizing 3D virtual garments using 3D apparel CAD system, presenting the utility and problems, evaluating the possibility of 3D apparel CAD system in fashion industry. For this study, we modified a 3D body scan data for a parametric body model and made three garment patterns-soutein collar blouse, tiered skirt and tight skirt. Also we tried virtual sewing and simulation considered garment pattern arrangement, physical characteristic of cloth, the size of suitable mesh, the number of times to calculate best simulation and textile. As a result of this study, 1. The 3D measurements using 3D apparel CAD system are different from direct measuremenst. For this reason, we need to development various method to landmark on the body and standardize the way of measure. 2. We can modify the 3D body model in 3D apparel CAD system but it occurred collision detection when there is a great difference between original and modified body model size. For this reason, it indicate the warning sign in the 3D apparel CAD system to prevent collision detection. 3. we can import pattern data from 2D apparel pattern system to use virtual sewing. But we have to diminish the modulate points of these patterns because the volume of data is to large. 4. We can make a simple patterns using 3D apparel CAD system, but this pattern system is hard to make complicate patterns including dart manipulation and grading. 5. It needs function of preventing extend if we sew the different stretch fabric. And also it needs sewing system to make various gather or shirring.
