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.

2. Since each of the 9 blocks comprising of the upper front shell have the different radiuses and features, the optimal matrixes for flattening are different each other and die combinations of the optimal matrixes are elated to the radiuses of the figures rather than to the dimensions of the blocks.
1-3). In this study, we partitioned upper front shell by 3 shells and wanted to found a standard for generate triangled in upper front shell.
제안 방법
The grids of one block became a piece. After getting dimension of the piece, analyzed eDifference ratio5 between the block and the piece and the 'Ratio by triangle', and then, the optimal intervals of the matrixes, which can include the figural features of each group according to the figures of the graphs, were selected. Rapidform2006 (INUS Technology, Inc, Korea)was employed for partitioning development parts and creating curves by a block.
Although an experiment to find out the optimal matrixes in each block was conducted by partitioning each block in this study, the curves of the blocks, which belong to a shell, should be made on the basis of the same matrix instead of making them separately in each block during the flattening process of the whole shell or model. Therefore, the optimal matrix should be selected not by the most efficient combina-tion in a block, but by the best combination in the whole shell while considering the connectivity of a block with the other ones.
As mentioned above, even the optimal matrix of each block was determined, the blocks in the same shell would rather create the curves on the basis of the same matrix than create curves in several for the flattening process of the whole shells or models. Because the purpose of this study is to make the optimal matrix of each block set up to standardize the matrix requiring on flattening 2D of the body figure.
In this study, the following conclusions were made in order to satisfy the exactness and efficiency of the surface flattening by using the Grid method with the 3D figure data of the female groups of the age brackets, such as 18 to 24 and 35 to 49, and to standardize the matrix of the automation process of the surface flattening of the 3D figure data that can show the fig- ural differences according the age.
In this study, we set up the optimal matrix per another block of Upper Front shell to UF1 block 4*9, UF2 block 2*7, UF3 block 5*4, UF4 block 5*4, UF5 block 5*4, UF6 block 5*4, UF7 block 1*3, UF8 block 3*4, UF9 block 2*4.
Suh(2001) changed 3D surface into triable mesh data usiri응 slice data which eases surface flattening. She arranged 3D mesh data on the focus of anthropometric base line, and changed 3D data information into flattening information. But, these studies can't connect apparel pattern in approximation of 3D scan data.
Therefore, this study is intended to suggest the criteria of the standardization of the process that flattens the 3D body figures to the 2D patterns by setting up the optimal matrix, which can cover the differences of the body figures according to the age by using the Grid method.
This study was held using 3D scan data ofspecific size and age group by representative body model. However, verification is needed using various shape and size to be inspected to generalize same results for body figures.
대상 데이터
In this study, YA82 model of size 82-66-91(165) in the age brackets of 18 to 24 and A88 model of size 88-7사-94(160 in the age brackets of 35 to 49 were selected as the targeted objects and 3 subjects of various body shape were selected for verification. In this way, the age and the size of the research objects are limited and the verification objects stays on a small number so that it is difficult to generalize the research result.
이론/모형
The curves are made by using the Grid method and Bridge method through the combinations of the matrix according to the stages of the blocks of YA82 and A88 models. The Grid method is to arrange the curves on the figures by dividing the width and height of the block into the numbers of the rows and columns.
성능/효과
3. Considering the areas are increased in most of the processes flattening the blocks, the flattening by the Grid method can be 듡sed for the productions of the nude patterns closely related to the bodies and it is considered that the increased areas can be used as the ease.
4. In spite of the figural differences between YA82 and A88 models, the standards for the block setting and the Grid methcxl are reasonable as the basis of the standardization for the simplification of 3D figure data since the optimal intervals and the matrixes are agreed each other.
In conclusion, it is judged that the methodology adopting the Grid method in this study is appropriate for the standardization for the data approximation, which enables the transformation of two-way data, such as the remodeling and the pattern developments between 3D data and 2D patterns. And the suitability of surface flattening criterion was confirmed because the verification using 3D figure data in various size and shape showed the similar tendency.
후속연구
In this study, the wearing evaluation for verification was not accompanied, because(mly the upper front shell of the 3D body figure was aimed to standardize for flattening. Therefore, the subsequent study should be progressed for the whole body.
