摘　　要：针对纹织CAD意匠工艺中的泥地效果模拟问题,对传统手工纹织物泥地绘制方法和效果进行提炼,基于知识表达和面向对象,构建专家传统手绘泥地方法的模型,创建不同类型的泥地粒子发射器、粒子影响器和粒子渲染器,将相应的泥地粒子发射器、泥地粒子影响器、泥地粒子渲染器进行组合,基于计算机图形学,对纹织物泥地算法进行实现,使泥地特效算法有效地应用于纹织CAD系统中。对纹织CAD泥地的效果实现进行了实验测试,结果证明基于粒子系统泥地效果仿真是可行的,不仅可以控制泥地的形态和随机性,还可设计出用手工绘制无法实现的泥地效果,极大地提高了效率,在自动处理花幅宽度为40 cm,花幅高度为40 cm范围的泥地时,意匠自动处理在1 min内。For mud effect simulation problems of jacquard fabric in CAD,the conventional method of fabric mud mapping is refined,expert experience model of convenitional hand-painted mud is built based on object oriented,different types of mud particle emitter,particle effects and particle renderer are created according to the characteristics of different types of mud,and the corresponding mud particle emitter,particle effects and mud particle renderer are arranged to create a variety of forms and effects.Based on computer graphics,the fabric mud algorithm are implemented,so that the mud effects of particle system algorithm is applied to the fabric CAD system effectively. Particle system is proved to be feasible by testing mud effect in the fabric CAD system. Particle system can not only control the morphology of mud and randomness,but also create effect of mud,which cannot be achieved by hand,and great efficiency is achieved in particle system. For example,the range of mud of the width of 40 cm and height of 40 cm can be automatically processed within 1 min.
