Modeling of virtual clothing and its contact with the human body

Abstract

Abstract Aiming to tackle the issue of virtual fitting, this study proposes an integrated solution encompassing key stages, such as fabric modeling, virtual stitching algorithms, and clothing–body contact mechanisms, with focus on simulating and calculating the clothing pressure. A fabric model based on a particle–spring system is developed, with an emphasis on exploring the relationship between spring coefficients to achieve parametric independence of the virtual fabric. To turn the fabric into clothes, an algorithm for stitch line generation is introduced along with discussions on springs with constraint to improve the rendering accuracy and enhance effects. For simulating the clothing–body contact, a body characterization model consisting of slices is constructed and utilized to compute fabric deformation and its pressure exerted on the human body. Validation tests are conducted by comparing calculated pressures with real measurements obtained from a mannequin, demonstrating an error of 10.9% for the fit size of clothing and below 10% for smaller sizes. These results indicate that the proposed solution not only enables realistic visual effects of virtual clothing but also generates meaningful pressure values based on fabric properties, clothing patterns, and sizes. This lays a solid foundation for the valuable assessment and prediction of clothing pressure in virtual fitting scenarios.
