Abstract

Many applications in computer graphics require complex and highly detailed models. However it is often desirable to use approximations in place of excessively detailed models in order to control the processing time. Thus, we aim to develop a notion of optimal matrix to simplify surface which can rapidly obtain the high quality 2D patterns flattening 3D surface as follows. Firstly, two 3D bodies are modeled based on existing Size Korea data. Secondly, each model is divided by shell and block for its pattern draft. Thirdly, each block is flattened by grid and bridge method. Finally, we selected the optimal matrix and demonstrated the efficiency and quality of the proposed method. This proposed approach accommodates surfaces with darts, which are commonly used in the clothing industry to reduce the deformation of surface forming and flattening. The resulting optimal matrix could be an initiation of standardization for pattern flattening. It is expected that this method could facilitate much better approximation in both efficiency and precision.

3차원 인체 형상에 적합한 의복 패턴을 제작하기 위하여 인체 형상을 평면전개하여 체표패턴을 얻기 위한 다양한 연구들이 진행되고 있다. 본 연구는 Grid method를 이용한 여성 상반신 앞면의 평면전개를 위하여 최적 그리드 기준을 결정하는 것을 목적으로 하였다. Grid method는 인체 형상의 표면에 커브를 생성하고 각 커브의 길이를 플로팅하는 원리에 의하여 3차원 형상을 평면전개 방법이다. 첫째, Young 모델과 Adult 모델에 해당하는 두 개의 3차원 바디들을 사이즈코리아데이타에 기초하여 모델링하였다. 둘째, 각각의 모델을 3차원 특징점에 의하여 shell과 block으로 세분화하였다. 셋째, 각각의 block은 다양한 그리드수의 조합에 의하여 평면전개되었다. 마지막으로, 가장 효율적인 조합을 선정하여 평면전개의 기준으로 제시하였다.
