【摘要】 计算机技术的不断深入发展，为纺织行业自动化和信息化程度的提高提供了巨大可能。其中，织物模拟技术是数码纺织领域的关键技术之一，它能直接利用计算机仿真出织物的实际表观效果，从而可省去试织的繁琐过程，极大的降低人力和物力的消耗，提高企业的竞争能力。 论文的绪论部分综述了织物模拟算法研究的历史背景以及应用前景，提出了算法的基本框架结构，然后阐述织物模拟算法的基本原理，并对各主要模型进行了分析：(1)基于纱线的光照模型，给出了纱线模拟的具体方法；(2)综合考虑影响织物外观的重要因素，进一步给出了简单花型织物的模拟算法；(3)针对复杂织物，给出了基于织物组织单元化的表层信息提取算法，并提出了结合人工智能技术进行织物表层信息判断的解决方案框架；最后，提出了模拟效果后期处理以及算法优化的方法以提高织物模拟处理速度。初步完成了织物模拟软件商业化开发，实际证明具有十分逼真的模拟效果。更多还原

【Abstract】 The further development of computer technology has provided a huge possibility of improvement of automatization and informatization in textile field. The weave simulation technique is one of the key techniques in the field of digital textile, and can directly make use of the real effect from the simulation results, thus avoid the process of weaving trial. As a result, the technique can greatly reduce the consumption of manpower and materials and enhance the competition.The introduction part of this paper first presents the background and the purpose of investigation in simulation algorithm and also the basic framework of arithmetic, and then, it introduces the original principle of the arithmetic and makes a close analysis of the main models: (l)gives a concrete yarn simulation algorithm based on yarn’s shade model; (2)considers of fabric model and puts forward the simulation algorithm for simple fabrics; (3) with consideration of the complicated textile, presents the algorithm of computing surface layer information based on dividing weave matrix into cells and combines the artificial intelligent technology to propose a framework to get the information of the textile surface. In the end, the paper presents the after-effects of the simulation and the way of arithmetic optimism as well. The finished Fabric Simulation CAD System proves to be capable of presenting a close result to real fabrics.更多还原
