摘要：

为了实现纬编提花织物的三维结构仿真和虚拟仿真,在深入研究各提花类型编织原理的基础上总结其仿真结构特点。通过数学建模的方法,建立提花织物中常用的线圈几何模型、线圈型值点模型和平移模型,借助矩阵运算可根据织物组织快速计算线圈的空间坐标位置。采用WebGL技术和三维图形引擎库Three.js,根据型值点空间坐标实现了三维线圈结构的绘制和颜色渲染,截取提花织物三维仿真图作为纹理材质,利用纹理映射技术实现纬编提花织物三维虚拟仿真。以各类提花效应的三维仿真效果为例对仿真方法进行检验,结果表明矩阵模型可以实现线圈型值点坐标快速转换与计算,WebGL技术可实现三维结构仿真可视化从而准确描述提花织物结构特征,增强服装虚拟仿真的真实感。

Abstract:

In order to simulate three-dimensional (3-D) structural and weft-knitted jacquard fabrics, the structural characteristics of simulation were summarized on the basis of the knitting principle of each jacquard type. By means of mathematical modeling, three types of loop geometry models, loop point model and translational model of jacquard fabrics were established. WebGL technology and 3-D graphics engine library Three.js were adopted for drawing and rendering 3-D loop structures according to the spatial coordinates of the loop points. The 3-D simulation was intercepted as texture material, and 3-D virtual simulation of weft-knitted jacquard fabrics was created through technology of texture mapping. The simulation method was tested with different types of jacquard effects. The results show that the matrix model is effective for the rapid transformation and calculation of the loop coordinates, and WebGL technology works for the visualization of 3-D structural simulation to accurately describe the structure characteristics of jacquard fabrics. Realistic virtual simulation of clothing was enhanced using this method.

Key words: weft knitting, jacquard fabric, WebGL technology, matrix model, 3-D structural simulation
