Three-Dimension Parametric Simulation of Knitted Fabric Based on the Twisted Loop Model

To enhance the realistic simulation effect of knitted fabric, a new three-dimension （3D） twisted loop model was proposed. This model was constructed by using Non-uniform Rational B-Spline （NURBS） surface. The control points of this surface were generated through rotating the cross-section along the center path of yarn. The cross-section of yarn was generated based on the two-level hexagonal ~lose packing model. Both of the center path and the cross-section were fitted by NURBS. With this twisted loop model, 3D parametric simulation of knitted fabric was realized in 3DS MAX by utilizing MAXScript and analyzing the relationships between structure parameters （including the wale-spacing, the course-spacing, the yarn diameter, .and the fabric thickness） and geometric model. The simulation of knitted fabric has 3D realistic twist effect dearly. Furthermore, the structure parameters and the twist parameters of fabric can be modified interactively.
