Structural optimization of yoga top based on 3D virtual-reality technology

Abstract

The pressure comfort of a sleeveless yoga top was evaluated and optimized based on three-dimensional (3 D) virtual-reality technology. A 3 D human modal and virtual sample pattern were created, contact pressure values on 23 points during 12 yoga postures were measured. Results showed that pressure values of side neck point, back neck point, shoulder midpoint, shoulder point, bust point and the intersection of back princess line and waist line of the 3 D sample garment fluctuated greatly, where the dynamic pressure comfort was poor. The structural optimization was based on the improvement of pressure comfort on above points. A verification carried out to verity effects of the optimization, it was demonstrated that the pressure fluctuation at above points was obviously reduced, which meant the dynamic pressure comfort was obviously improved. It is expected that the research results can provide not only a yoga top pattern with excellent dynamic pressure comfort but also a reference for the future application of 3 D virtual pressure values in clothing.
