摘要: 为了构建具有多种截面的三维纱线通用模型,探讨了用B样条曲线近似设计圆形、椭圆形、跑道形、凸透镜形、矩形和碗形等纱线截面的方法,在此基础上用B样条曲面装配多段纱线,构造出同一根纱线可以有多种不同截面类型的三维模型。

Abstract: In order to construct a universal 3D yarn model with different cross sections,the design methods of yarns with such cross sections as circle,running path,convex mirror,rectangle,and bowel by B-spline curve were investigated.Then,the B-spline surface was used to connect several sections of yarns and construct a single yarn having different cross sections 3D model.
