摘要: 为探索计算机模拟纬平针织物的新方法,更加真实地反映其三维结构,在Pierce二维纬编针织线圈模型的基础上,根据针织物空间几何结构的特点,建立了三维几何线圈模型。它由几段用参数方程表示的空间圆弧和曲线连接组成,通过OpenGL程序设计和库函数中的球体模型,在Visual C++编程环境下实现该线圈模型。研究和模拟结果表明,采用这种建模和实现方法,无需消隐处理,可较为逼真地显示出纬平针织物线圈在三维空间中相互串套的效果。

Abstract: In order to explore a new method of computer simulation on plain weft knitted fabric and to show its real three-dimensional structure, based on Pierce′s 2-D weft knitted loop model and the feature of knit geometry configuration in space,a 3-D geometry loop model is constructed.Comprising several spatial arcs and curves represented by parameter equations,the model is implemented under the(VC++) programming circumstance by OpenGL drawing program and the spheroid technique in its library functions.The result of research and computer simulation indicate that the modeling and implementing method can give vivid effect of plain knitted fabric with 3-D intermeshed loops without the need of concealment processing.
