Abstract:

With detailed research on the structure of warp-knitted fabric, the spatial yarn position of a 3D loop structure was discussed, and the dimension of each parameter was ascertained. After establishing the basic control points of the loop, a 3D model of warp-knitted fabric was created. By calculating the control points of this model in reverse, a more exact control polygon was attained. By utilising the program Visual C++ and the developing tools of Open GL, using Non-Uniform Rational B-Spline surfaces, spatial yarn can be described exactly, and a virtual reality of warp-knitted fabric can be realised on a computer screen.
