Comparison of Avatar Posture Formation According to 3D Virtual Garment Modeling Programs-Focusing on Cycling Movements of High-School Male Cyclist-

Abstract

The study aimed to analyze the functional differences in 3D virtual garment programs and compare body scan data with the corresponding 3D virtual models. We selected 3D virtual garment programs, formed virtual models in a representative size for high-school male cyclists, and analyzed them using the Design-X program. The results were as follows. In the 3D virtual garment programs, the anthropometric items for virtual model forming differed significantly from the standard anthropometric items suggested by Size Korea. Comparing the lower body scan data and virtual models formed by the 3D virtual garment programs, the biggest difference was in the shapes of the waist and hips, i.e., the flatness values of the waist and hips were different for each program in the cross-section view. In the lower body, a data-input-based program was needed for changing the exact measurement position of the waist circumference and hips'' shape in detail. If a 3D virtual garment program provides functions for the virtual model''s joint angle input and free motion transformation, it is expected to be widely used in the sportswear industry.
