20대 성인 남성 상반신앞판형상의 평면 전개를 위한 표준화 연구

Abstract

The purpose of this study is to propose a standard of converting 3D shape of men in twenties to 2D patterns.This can be a basis for scientific and automatic pattern making for high quality custom clothes. Firstly, representative 3Dbody shape of men was modeled. Then the 3D model was divided into 3 shells, front, side and back. Among them, thefront shell was divided into 4 blocks by bust line and princess line. Secondly, curves are generated oneach block accordingto matrix combination by grid method. Then triangles were developed into 2D pieces by reflecting the 3D curve length.The grid was arranged to maintain outer curve length. Next, the area of developed pieces and block were calculated anddifference ratio between the block area and the developed pieces’ area is calculated. Also, area difference ratio by the num-of graphs. The optimal matrix was set considering connection with other blocks. Curves of torso upper front shel wereregenerated by the optimal matrix and developed into pieces. We validated it's suitability by comparing difference ratiobetween the block area and the developed pieces’ area of optimal section. The results showed that there was no significantdifference betwen block area and the pieces’ area developed by optimal matrix. The optimal matrix for 2D developingcould be characterized as two types according to block’s shape characteristics, one is affected by triangle number, theother is affected by number of raws more than columns. Through this study, both the 2D pattern developing from 3D bodyshape and 3D modeling from 2D pattern is possible, so it’s standardization also posible.
