摘要
针对传统的织物模拟方法是基于纱线的圆柱形数学模型设计,只是简单地把纱线抽象化,并没有考虑到纱线本身的属性与光照明暗效应,导致模拟出的纱线表面亮度渐变过快,效果生硬不理想,对二重织物真实感的模拟效果不够逼真,提出了一种二维织物模拟的新方法。从二重组织的构成条件出发,导出二重组织的判别条件,并由此建立纬二重组织的数学模型,从而得出二重组织织物的正反面组织图;再结合纱线模型与织物交织模型,实现对二重组织织物的真实感模拟。实验表明,该方法能够实现真实的二维织物模拟,取得不错的效果。
Traditional fabric simulation method,is based on the mathematical model of the yarn cylindrical,is simple Abstraction of the yarn,and it doesn＇t take into account the properties of the yarn and light and shade.It will lead to sharp gradient of the simulative surface brightness and unsatisfactory simulation result of the weft backed fabric.In order to solve this problem,this paper put forward a new 2D fabric simulation method.From the structure of the weft backed fabric,the method derived the criterion and established the mathematical model of the weft backed fabric.Combined the yarn model and weft backed fabric model to realize the realistic simulation.The simulation effects show that the method is feasible.
