Abstract: 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.
