3D simulation of flat-knitted shaped shoe uppers
Wenmin Gu, Gaoming Jiang, Bingxian LiPurpose
Research on simulating shaped shoe uppers is still in its early stages. Most studies focus on simpler cut uppers, using texture mapping principles to directly map loop patterns onto curved surfaces. Although this method simplifies the simulation process to some extent, it fails to fully capture the complex details and realistic textures of the shoe uppers. For applications requiring high-precision simulations, the current technology clearly has limitations. Therefore, developing more refined and accurate methods for simulating shaped shoe uppers becomes particularly important.
Design/methodology/approach
This study focuses on flat-knitted shaped shoe uppers, delving into the knitting processes and the selection of different organizational structures for various regions of the shoe upper. It also comprehensively examines the basic principles of optimizing and reconstructing DXF files, as well as the three-dimensional (3D) simulation workflow.
Findings
The study addresses the issue of 3D surface control points exceeding OBJ boundaries, proposing a rational and efficient surface triangulation indexing method that successfully resolves this challenge.
Originality/value
This study helps in enabling the rapid transformation of planar loop meshes and shape value points onto curved surfaces. It also allows for the precise acquisition of the spatial coordinates of the shape value points for each loop in the fully-fashioned shoe upper and also helps in achieving the digital design and 3D simulation of flat-knitted shaped uppers through the implementation of loop structures.
