Drape Evaluation of 3D Garment Simulations for Flared Skirts

Abstract

The virtual try-on technologies of the current level have limitations with material expression as well as some difficulties with commercialization. There are differences in simulation results and subjective evaluations perceived by consumers according to the types and physical characteristics of materials used in virtual try-on simulations. This study were to analyze the exterior clothing shapes and visual images from 3D virtual try-on simulations with materials whose drapability was differentiated and then test the accuracy of the expression of the drapability of the materials. The study carried out 3D virtual try-on simulations by selecting flared skirts as an item to best express differences in drapability along with five materials of different physical properties and offered some basic data for greater utilization of virtual tryon simulations by comparing and analyzing them with the exterior shapes and visual images of actual flared skirts. The analysis results of hemline shapes between actual and virtual try-on according to the types of materials showed no match among the quantitative items of exterior shapes factors. There were no significant differences in the visual images except for "soft" according to the simulation methods, which means that the items can serve as part of a scale for visual image comparison. It is necessary to reflect quantitative numbers regarding "drapability" proposed in the study simulation software and to continue to build a systematic database for virtual simulations by investigating and testing various materials.

CLO3D Simulation versus Real Drape Test for Assessment of Garment Drape Coefficient

“…It has been reported that no numerical values can be used individually to assess the drapability of fabric through the analysis of the final form of the garment. It differs according to the categories of drape (stiff or drape fabric) [17]. The particle distance of virtual garment fabric must be considered, as it is highly effective on the reality of the garment's appearance [13].…”

An Investigation on the Virtual Prototyping Validity – Simulation of Garment Drape

“…In other studies, different approaches used for identification of virtual prototyping reliability and validity, for example measurements and analysis of drape distances; analysis of correlation between drape coefficient of materials and the exterior shapes and visual images; comparison of actual and virtual hem lines etc. (Lee J., 2014) For example, in a study, where simulations made on customised default 3D model and 20 real samples produced, is claimed that photographs for the front, side and back views are taken instead of use of 3D scanning because of noises and missing parts of scan. It could be related to the research year, because currently such problems can be avoided.…”
