摘要：

为实现少梳经编色织物的仿真与服装的虚拟展示,便于分析少梳经编织物的编织原理和结构特点,通过测量与分析实际线圈尺寸建立经编线圈几何模型,根据每把梳栉垫纱数码的规律,建立了单根纱线的线圈坐标数学矩阵与坐标平移矩阵,利用矩阵运算得到少梳经编色织物线圈的坐标。采用Web中的双缓存技术分别绘制每把梳栉的线圈和延展线,并进行叠加组合实现仿真;然后利用截图手段获得花型纹理单元,并基于纹理映射技术实现服装的虚拟展示;最后通过与实际织物对比仿真结果进行检验。结果表明,该方法能够准确模拟少梳经编色织物的尺寸与花型,实现可视化设计与展示。

Abstract:

In order to simulate and virtually display the few-guide bar yarn dyed fabrics, and analyze the knitting principle and the structure characteristics, based on the measurement and analysis of the actual stitch size, geometric models for stitches were established. Matrices for coordinates of stitches and transformation were adopted to obtain the stitch coordinates of the whole fabric according to the chain notation. Double buffer technology in the Web software was used to store the canvases with stitches and underlaps, which were superimposed together to implement the simulation. The pattern texture was captured as a screenshot, which was displayed on garment models by texture mapping. The simulated results were validated by comparing bitmaps of the real fabrics and the simulated ones. This research indicates that the method adopted is able to precisely simulate the pattern and size to achieve the visual design and display.

Key words: few-guide bar yarn dyed fabric, geometric models for stitches, garment virtual display, knitted fabric simulation
