Computer simulation of three-dimensional woven fabric

In view of the defect and shortage in computer simulation of woven fabric, a three-dimensional woven fabric simulation algorithm and program are realized. Analyze the hierarchical structure of three-dimensional woven fabric, then design the algorithm of yarn interlacing model and trajectory calculation and yarn data storage structure in three-dimensional coordinate system. The warp and weft yarns are composed by several spatial arcs and straight lines connecting with each other expressed with the parameter equation. The simulation is achieved by a series of three-dimensional spherical model drawn by OpenGL library functions and Visual C++ along the calculated coordinate values. This modeling and simulation method, without blanking, can be more realistic to show the effect of three-dimensional woven fabric yarns interlaced with each other in three-dimensional space. Designers can preview the effect of finished product before weaving, so as to facilitate material development officer for analysis and design.
