| Abstract: | It has been difficult to obtain the fitted bra wire shape for women’s breasts, since the under breast root shape extracted from 3D bodyscan breast images is three dimensional. A detailed matrix algorithm for the geometric relation is firstly introduced and presented for transferring the 3D bra wire shape to one that is 2D to create a fitted bra underwire shape prototype. In this paper, the under breast root shape was extracted from a medium average avatar, then the curve line was exported as a point format. Points were taken as research subject, then the transformation matrix algorithm was applied to the spatial coordinates of the points to fulfill the transformation. Thereby a detailed program was operated in MATLAB for obtaining the coordinates of points to create the contour for the 2D wire shape. The matrix algorithm method was a useful, simple and straightforward method to implement. In addition, it works well for various kinds of breast shapes. |
