织物影光设计研究

探讨了织物直丝影光、横丝影光、斜丝影光等3种阴影彤式的计算机实现的设计思想、数学模型和流程图。影光处理采用人机交互的方式进行，在纹样上确定影光层次区域，通常用画多边形拟合曲线的方法先在纹样中画出，然后确定变化方向，由计算机点绘出从经面到纬面或从纬面到经面逐步过渡的影光层次。最后，在各教学模型的基础上，给出了用VC编制的对应功能函数，并且在586计算机上成功地运行了各函数，验证了各数学模型的正确性。得到的各教学模型，不仅是织物进行意匠设计后继工作的先决条件，而且就其数学模型的设计思想可以拓展到许多计算机图形处理领域。

The Research of Jacquard Hatching Design

This paper introduces the new way of three kinds hatching design in Jacquard: straight shadiness, horizontal shadiness, diagonal shadiness, discusses the computer design thoughts, mathematical models and flow diagrams of three kinds hatching pattern. The shadiness carries out adopting man-machine mutually, decide shadiness order district on the design draft. First drawing these using polygon combine curve methods, then Juniding the change directions, drawing the shadiness order which from warp flush to weft flush or from weft flush to warp flush. Last, on the bases of all themathematics models, the paper gives the parallelism function of VC, and these models are proved that they are right by running in 586 computer. All above the models not only are the base of draft-manipulation, but also can be explored many fileds of computer graph manipulation.
