织物模拟CAD系统的开发与实现

针对国内纺织CAD软件模拟功能相对较弱的现状，旨在提出一套织物模拟CAD系统的开发与实现方法。首先充分考虑纱线的三维特性并结合计算机图形学技术建立其表面光照模型，然后结合各模拟参数分析、判断，提取出织物表层信息，最后考虑浮长线对织物外观的影响，实现了对织物外观的模拟，模拟效果具有较强的真实感。另外，系统各模块都保持了较高的独立性，模块间的耦合关系也较为松散，以利于系统后期的维护和升级。

The Development and Realization of Weave Simulation CAD System

In this article, the authors establish a new method of developing weave simulation CAD system. Firstly, a mathematic model for yarn simulation is set up, which is based on light and shade effect generated by illumination. And then, after abstracting the surface layer information of woven fabric, the authors finally realize the weave simulation, with the floating principle fully considered. Besides, each functional module is designed to be relatively independent, which is helpful for updating system in the future.
