This paper proposes a simulation method suitable for weft-knitted seamless kneepads. The purpose of this study is to realize the simulation of complete weft-knitted products, and it has the advantage of speed to display the simulation results online in real-time. The loop of the basic loop model is controlled by up to eight characteristic points and the yarn path is fitted by a three-dimensional spline curve. To string the loop model into the fabric, the coordinate of the characteristic point of the loop at other positions is obtained based on the loop model at the origin by using the translation matrix and the rotation matrix. The simulation 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 simulation of the kneepad with high efficiency. This method has strong real-time performance and practicability.

本文提出了一种适用于纬编无缝护膝的仿真方法。本研究的目的是实现对完整纬编产品的仿真，在线实时显示仿真结果具有速度优势。基本线圈模型的线圈由多达 8 个特征点控制，纱线路径由 3 维样条曲线拟合。将毛圈模型串入织物中，利用平移矩阵和旋转矩阵，根据毛圈模型在原点处得到毛圈其他位置的特征点坐标。纬编护膝的仿真是通过Visual Studio和WebGL的联合编程实现的。结果表明，该结构模型能够高效地实现对护膝的仿真。
