Abstract

To realize three-dimensional (3-D) simulation of weft-knitted fabrics, this paper proposes a 3-D loop modeling method which includes yarn texture and rapid deformation of fabric. The deformation of the fabric is achieved using a simplified particle system. In this study, the shape of the loop is controlled by using 10 control points, and the coordinates of the loop type control points are calculated in combination with the actual loop shape and a quadratic Bezier curve equation. To realize the deformation of the loop, the relationship between the control points and the particle system is established. The 3-D surface model of the yarn is constructed based on a local frame of the loop path. In addition, the yarn simulation is achieved by texture mapping. The simulation of fancy weft-knitted fabric is realized by the joint programming of Visual Studio and OpenGL. The results show that the simplified particle model can accurately achieve the deformation of the fabric with high efficiency. The geometric model properly represents the loop shape and exhibits the yarn texture.
