全成形双层结构针织服装部件化虚拟展示研究

针对双层全成形服装开发少且虚拟展示实时性欠佳的问题,在分析全成形双层服装的异形结构样板模型特征要素基础上,对部件化分类后的双层样板模型进行参数化设计,并建立二维样板与三维样板模型的拓扑几何映射关系,应用弹簧–质点模型实现里外层二维样板的三维部件化建模,通过使用数字化纱线仿真模拟与纹理映射技术,对纹理映射后的二维样板的工艺结构特征点进行校准对位,最终实现了全成形双层针织服装无缝化部件虚拟建模设计与快速虚拟仿真展示,为全成形异形结构类针织服装的系列化产品开发与快速交互提供创新方案。

Research on virtual display of fully-formed double-layerknitted clothing parts

In order to develop double-layer fully-formed knitted clothing with high quality real-time virtual display, the parametric design of the double-layer template model after component classification was carried out based on the analysis of the characteristic elements of the special-shaped structure template model of fully-formed double-layer clothing. The topological geometric mapping relationship between two-dimensional template and three-dimensional plate model was established, and the three-dimensional component modeling of inner and outer two-dimensional template was achieved by using spring mass model. Through the use of digital yarn simulation and texture mapping technology, the structural feature points of the two-dimensional plate after texture mapping were calibrated and aligned, and the virtual modeling design and rapid virtual simulation display of seamless parts of fully-formed double-layer knitted clothing were realized. This work provides an innovative scheme for the development and rapid interaction of series products of fully-formed special-shaped knitted clothing.
