纹织CAD中冰片泥地算法的实现

Implementation of Borneol Mud Algorithm in Jacquard CAD

为降低冰片泥地组织设计的复杂性,提高设计效率,使冰片泥地效果更好地应用到装饰纹织物的花型设计中,根据冰片泥地的特点,在纹织CAD中利用种子膨胀算法,进行计算模拟实现冰片泥地的效果。以圆形渐变冰片泥地为例,种子点分布的初始位置以原点为中心,逐渐向外扩散,种子点密度也随向外扩散而变稀疏或紧密,从而实现冰片泥地效果。测试表明:用种子膨胀算法实现冰片泥地是可行的,不仅可以控制冰片泥地的形态和随机性,还可以绘制出用手工基本无法实现的渐变冰片泥地效果。本设计方法给纹织CAD装饰纹织物意匠图的设计带来了方便,为数码化的装饰织物设计提供技术基础。

In order to reduce the design complexity of borneo1 mud weave, improve the design efficiency and better apply the effect of borneol mud in pattern design of decorative jacquard-weave fabrics, according to the characteristics of borneol mud, seed expansion algorithm is applied in jacquard CAD to conduct computational simulation so as to achieve the effect of borneol mud. Take circular gradient borneol mud for example. The initial position of seed point distribution is centered at the original point and spreads out gradually. The density of the seed points also becomes sparse or sense with the diffusion so as to achieve the effect of borneol mud. The test proves it is feasible to achieve borneol mud with seed expansion algorithm. Not only the form and randomness of borneol mud can be controlled, but also the effect of gradient borneol mud which cannot basically be implemented by hand can be drawn. This design method brings convenience for design of jacquard CAD decorative fabrics and provides technological base for digitalized design of decorative fabrics.
