Abstract
This paper proposes a virtual display method suitable for a weft-knitted seamless kneepad. The purpose of this study is to realize the virtual display of complete weft-knitted products, and it has the advantage of speed to display the virtual display results online in real-time. The basic loop of the model is controlled by up to eight characteristic points and the yarn path is fitted by a three-dimensional spline curve. First, the characteristic point coordinates of the seamless weft-knitted kneepad in the plane state were calculated, and then the corresponding spatial coordinate transformation matrix was selected according to the corresponding mesh of each loop to calculate the characteristic point coordinates in the wearing state. Finally, the virtual display model of the seamless weft-knitted kneepad was rendered by tubeline geometry. The virtual display of the weft-knitted kneepad is realized by the joint programming of Visual Studio and WebGL. The results show that the structure model can achieve the virtual display of the kneepad with high efficiency. This method has strong real-time performance and practicability.
