摘　　要：为提高织物外观真实感模拟算法的效率,提出一种改进的、简洁高效的织物外观模拟算法。在织物外观仿真中,通过优化纱线模型,并利用计算机图形学中的多边形深度缓存算法,结合织物中纱线的反射特性,以及浮长线对织物外观的影响,建立了基于浮长线的屈曲模型,最后结合图像技术,使模拟的织物具有较强的真实感。实验结果表明,这种算法利用二维图像方法达到三维模拟的目的,降低了运算复杂度,提高了效率。In order to improve the efficiency of fabric appearance simulation algorithm, an improved fast algorithm of fabric appearance simulation was put forward. We improved the yam model, and established a buckling illumination model based on fabric floats by using polygon depth-buffer algorithm of computer graphics, in combination with the reflective trait of yarn and the effects of fabric floats. Finally, utilizing image technology, the simulated fabric has a stronger true sense. The results of experiment show that the algorithm which uses methods of 2-D images reaches the purpose of 3-D simulation, greatly reduces operational complexity and enhances efficiency.
