摘要
在三维服装虚拟缝合及试衣过程中,服装二维裁片虚拟模拟是关键技术之一。应用服装CAD软件绘制服装纸样并存储成DXF格式,通过DXF文件接口程序将纸样载入系统。采用正则栅格法对裁片进行四边形剖分,连接四边形对角线完成对二维裁片的三角网格化。以三角形顶点为质点,三角形边为弹簧,构建裁片质点-弹簧模型,通过模型受力分析、数值求解,完成对二维裁片的虚拟模拟。以男士背心为例,通过裁片网格剖分实验验证正则栅格法的有效性;同时完成对背心裁片自然下落于桌面和背心虚拟缝合效果模拟。
The simulation of 2-D patterns is one of the most important steps during the 3-D garment virtual stitching and try-on.The patterns were obtained using a garment CAD system and stored into a DXF formate which can be loaded from a DXF file interface program.And the patterns were meshed based on the regular grid method and the triangulation was completed through linking the diagonal of the quadrilateral.Then the mass-spring model was established,in which the vertex was the mass point and the edge was the spring.Finally,the stress analysis and numerical solution were employed to finish the 2-D patterns virtual simulation.The patterns of man's vest were taken as an example to verify the validity of the regular grid method and realize the effect simulation of 2-D patterns naturally fell on the desk and virtual-stitching of the vest.
