Abstract: Pattern design is a core activity of fashion design and garment development. The task of translating a design into pattern parts, as quickly and accurately as possible, is one which the fashion industry has been intent on perfecting for many decades. A garment is a three-dimensional, soft-fabric fabrication, the cloth from which the garment is made is traditionally cut in to two-dimensional panels, and between the process of design and pattern cutting, the dimensions of the pattern parts may be subject to error and resource considerations. The pattern parts which are required to make a garment are usually obtained by one or two methods, these being flat (2-D) pattern cutting and/or the modeling (3-D) method, the latter being largely dependent upon the designers' experience. Both of these methods are hard to master, and therefore, considerable expertise is required. The development of computer technology has supplied a number of alternatives to the traditional, pattern cutting methods. Computer-aided-design (CAD) and related, 3D technology can ensure that flat patterns are automatically generated and that simulations of the sewn pattern pieces may be viewed in a virtual, 3-D mode. The interface for a user still involves the use of a 2D screen to show 3D objects and 2D interactive tools for further manipulation and modification. The necessity of using 2D images to convey 3D objects requires imagination on the part of the user, in addition to which, valuable time may be lost in archiving the subsequent results.
In this research, a new system with 3D interface was proposed and developed. It uses an interactive mannequin and 3D digitizer as the interface tools for a user. A user can employ the 3D digitizer in the same way as a traditional pen to draw on the physical mannequin surface, and the lines drawn can be transformed into digital information, then sent to a PC, and viewed on the screen in real-time. When compared to the existing interactive 3D garment CAD systems, this one may be said to change the 3D design process from a virtual, to a physical one. As a consequence, the user could carry out his or her design work in a real, rather than a simulated, 3D world. As a result of the research and the subsequent findings, such a system will ensure a more continuous and more visualized design process, making it easier to draw, and subsequently modify, pattern parts. In addition, it will greatly reduce the pattern design time by removing the consuming task of converting a 3D design concept into 2D flat patterns. A further advantage is that the aesthetic merits of the garment can be visualized in advance of the sewing stage. The findings of the research present the possibility of a new system, offering a promising pattern design solution to the fashion industry, which can also be used as a teaching tool in fashion education. Fashion designers can then 'draw' the required fashion design to obtain the pattern automatically. It is considered to be highly compatible with existent CAD techniques and capable of modification or adaption for a variety of uses in the future.
