基于三次样条的三维服装模型的建立

根据标准女体服装人台表面的部分三维测量数据,进行经、纬向的三次样条插值计算,获得服装人台表面型值点间的插值点三维坐标,采用小平面逼近的方式应用OpenGL的图形功能,建立计算机三维服装人台的模型,并实现参数化控制,以获得不同体型和尺寸的服装人台模型。在服装人台模型的基础上,根据人台与服装间的对应关系,求得服装造型关键点的三维坐标数据,利用OpenGL的图形功能建立计算机三维服装模型。并应用VC++的FMC的对话框模式,实现利用便捷的人机界面对服装人台的参数化控制和不同服装款式的选择。

3-D modeling for garment based on cubic spline

According to the three-dimensional(3-D) data of some points measured on the surface of a standard woman mannequin,we obtained more new interpolated 3-D data between the measured control points on the mannequin by cubic spline method in warp-wise and weft-wise,and built a parametric 3-D model for different mannequins in form and size with graphic functions of OpenGL.The surface of the mannequin was fitted by small quadrilateral planes.Then based on the model of the mannequin and the relationship between mannequin and garment,the 3-D coordinates of the key points for garment modeling was developed and the computerized 3-D model of garment for different styles was established with OpenGL.We present an interface with VC FMC dialogue frame to select styles of garment interactively and control the mannequin parametrically.
