摘　　要：二维样版设计修改是服装虚拟设计中的关键环节。通过OpenGL函数和三次NURBS曲线构建样版轮廓线,采用调整NURBS权因子的方法对曲线形状进行修改;基于改进Delaunay三角化方法对样版进行网格划分,构建映射到拉伸矢量三维空间的二维样版,实现网格密度的自适应控制,完成对二维样版模型的模拟;定义省道数学模型,对二维样版轮廓进行省道插入模拟。以服装袖片和裙片为例进行样版设计和修改,结果该方法能够提高服装衣片设计修改的效率,便于设计人员使用。Two-dimensional pattern design is a key process in virtual garment design. Pattern outline was created by OpenGL function and cubic NURBS curve methods. Mesh generation was made to pattern according to the improved Delaunay triangulation method. And a two-dimensional pattern which could map to the three-dimensional space was built. Finally,the mesh density could be adjusted with the shape of stretchable mesh, which was caused by the modification of the outline of the two-dimensional pattern.Mathematic model of dart was defined, and inserting dart into pattern was simulated. Sleeve and skirt pattern was designed by the proposed method. The results show that the method can improve garment pattern design efficiency and be user-friendly.
