领口、袖口、裤口等是三维服装模型上的重要部位,这些部位的提取、计算和编辑在三维服装合体性设计中有着重要的研究价值.首先对服装模型进行预处理如去除孤立三角片和孔洞修补,然后提取服装模型上边界点并使用三次非均匀B样条曲线拟合边界线,通过累加弦长参数法计算边界线的长度,最后采用平行切面投影边界点的方法适当增加空间数据点,用三角剖分得到延展的边界曲面.该方法可用于三维服装模型的局部调整和编辑.

Neckline, wristband and pantalets are key parts of 3-D garment models. The extraction and editing on these boundaries play an important role in the 3-D garment fitting design. The garment mesh model firstly is pretreated by removing isolated triangles and repairing the holes . After extracting border points, it uses the non-uniform cubic B-spline curve to interpolate them and calculates the length of each boundary. Finally, a parallel tangent plane based on border points is constructed to add new points and . create the extended border surface by the triangulation process. This method can be applied for the local adjusting and editing of 3-D garment mesh models.
