GENERATING SEAMS and WRINKLES for VIRTUAL CLOTHING

The generation of overall wrinkles on garment surfaces can be achieved by either introducing accurate cloth models with full collision response or by providing geometric wrinkle functions. Small wrinkles such as rippled appearance along seam lines have not been fully studied. Boundaries between different panels are often excluded from most garment draping simulations resulting in unrealistic appearance. This paper describes a new method to model realistic wrinkles on clothes via seams. The proposed seam model of tension pucker is simple and is easy to incorporate into a mass spring model with improvements over wrinkled appearance. We present a method that automatically constructs a seam surface along an arbitrary path on the surface of an irregular mesh. As an extension of modeling of seam pucker, we also apply the seam model to 3D garments.
