Patterns simulation in the 3D virtual stitching and try-on system

PurposeThe paper presents a method for the patterns simulation in the 3D virtual stitching and try-on system.Design/methodology/approachFirst, the patterns are designed using the garment CAD software and stored in the DXF format. Second, the regular grid method is employed to mesh the patterns to be quadrangular, and the patterns triangular meshing can be obtained by connecting the diagonal of the quadrangular. Then a mass-spring model is established, and the forces analysis and the explicit Euler integration method are employed to accomplish the patterns simulation. The paper demonstrates the robustness of our simulation through two sets of experiments, including a lady’s dress patterns meshing experiments and the experiments of the virtual stitching of the lady’s dress.FindingsThe patterns meshing algorithm can meet the requirements of the internal meshing and the boundary meshing, and it is very important to select an appropriate meshing density. The implementation of the virtual stitching of the lady’s dress proves the effectiveness and usability of the simulation methods.Research limitations/implicationsThe lady’s dress used in the experiments is a relatively simple fashion style, with only the front and back pattern. It is very worthy of further research on the effectiveness of the complex structure of clothing.Practical implicationsThe paper includes practical implications of the methods of the patterns meshing and the virtual stitching of the simple fashion styles.Originality/valueThe simulation system is developed using VC++ 2015 with the help of the OpenGL functions library, which is proved as a simple, lower computation and robustness for the patterns simulation of the simple garments.
