Three-dimensional simulation of weft-knitted jacquard fabric based on WebGL

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. © 2021, Periodical Agency of Journal of Textile Research. All right reserved.
