摘　　要：为对经编针织物的结构特征和外观效果进行预测,通过分析普通经编针织物的线圈结构,对O Goktepe的三维实体纱线模型进行了改进,得出线圈三维结构尺寸。利用非均匀有理B样条(NURBS)曲线和曲面原理,建立经编组织成圈线圈和衬纬线圈的三维实体模型。运用这些三维线圈模型,结合经编组织的垫纱数码,实现各种形态线圈的自由连接;最后运用Visual C++和OpenGL开发工具,将织物的光照和材质因素引入织物三维结构模型中,成功实现对单梳和双梳经编组织的三维模拟。In order to predict the structure characteristics and appearance effect of warp-knitted fabrics,O Goktepe′s 3-D solid yarn model is improved based on the study of normal warp-knitted loops,thus the 3-D dimensions of the loop can be obtained,with the principles of non-uniform rational B-spline（NURBS） curves and curved surfaces,the 3-D loop models of stitches and inlay of warp knitted structures are built,then with these 3-D loop models and according to the chain notations of warp-knitted structures,various kinds of loops can be connected freely,finally,with the tools of Visual C＋＋ and OpenGL,3-D simulation of single-bar and two-bar warp knitted fabrics is successfully realized by introducing the factors of fabric light and material quality into 3-D structural model.
