Computer animation of woven fabric deformation based on simple trellis model

Summary form only given. We describe a micro deformation model of woven fabric deformation for computer animation. In simulating the woven fabric deformation, we do not deal with precise mechanical models. We have adopted the crimp theory proposed by Peirce, as the geometrical model of our model, using a surface model which represents threads constructing woven fabrics. The Bezier surface is chosen as the surface model because it allows for the representation of smooth and complex shapes by a few points, called the control points. Coordinates of the control points in three-dimensional space are determined by approximation using the geometric model. Since the control points correspond to the surface shape, the movement of the control points deform the geometrical model. In this paper, we use a simple trellis model which permits us to represent the anisotropy of the woven fabrics. The computer animation of the woven fabric deformation created by the proposed method are shown.
