BackgroundThe fashion industry is highly competitive and the increasing use of computers in garment design reflects the desirability of reducing the time taken from the fashion designer's initial drawing to the large scale manufacture of a garment. It is currently possible for the fashion designer to create two-dimensional drawings of garments with relatively inexpensive PC software, but prototype garments must be made before the final form can be established. The ability to visualize the drape of a garment around the human form at the initial design stage would eliminate much of the time currently taken in making prototype garments. In addition, images produced by the drape software could be used both for demonstrating the garment to the client and for the production of patterns from which the garment is made up.The concept of a customer selecting a garment for purchase from a television or computer screen image showing the garment draped over his or her own body model is not too futuristic and has already been suggested as a future marketing method. Simulations of fashion shows are already available. These catwalk images are produced either by animating designers' artwork[1] or by using physical models. Magnenat-Thalmann and Thalmann[2] and Carignan et al. [3] discuss the animation problem in the context of the physical models currently available.In the present study the primary objective is to simulate the behaviour of a simple cloth garment as it falls into contact with a human body model from an initial position. The simulation must be sufficiently realistic for the garment designers' needs and be carried out quickly enough for the designer to work, ifThe current project has been supported by Coats Viyella plc and the EPSRC under a Case studentship held by Anne Bricis. Dr Ronnier Luo, now of Derby University, was instrumental in specifying and co-ordinating the project proposal. Professor Peter Jones of the Department of Human Science kindly made available LASS body data for the project and Dr R.H. Gong of the University of Manchester Institute of Science and Technology (UMIST) kindly supplied measured properties for material samples supplied by Coats Viyella plc. The authors wish to thank the EPSRC, Coats Viyella plc, Professor Jones, Dr Gong and Dr Luo for their assistance, support and co-operation.
