A Study on Expressivity of Virtual Clothing made of 3D Apparel CAD System according to the Physical Properties of Fabric

Abstract

This research was conducted to provide basic data to improve expressivity required for virtual clothing to replace actual clothing. For the experiment, 6 materials were selected and 12(2 kinds of length) actual flared skirts were made. At the same time, simulations were carried out on OptiTex Runway 12.0 for 36(12 kinds of skirts × KES, FTU, KES weight/10) kinds of virtual flared skirts, which were applied with the measured property values (thickness, weight, bending, shear, friction, and stretch). Also, the study compared and analyzed the wearing images, silhouette overlapping images, and skirt length measurements of the actual and virtual skirts put on a dummy. As a result, the actual skirts showed clear distinction for each material. In contrast, virtual 1 and 2 expressed fabric 3 in the most similar way, but could not recreate the uniform, soft, and natural flare shape of the actual skirts in general. Virtual 3 formed natural flares as those of the actual skirts, and expressed fabric 1, 5, and 6 in a similar way. However, virtual 3 had too much volume and barely showed any distinction for each material. All of virtual 1, 2, and 3 expressed different flare shapes on the front and back sides of the skirt similarly to the actual skirts, and had a good visual expression for the color and texture of the materials. However, they could not effectively express the elasticity and fabric sagging in the bias direction.

A model for predicting the similarity between real and virtual T-shirts based on sensory evaluation and image quantitative index evaluation

“…Cha 9 studied the expression forms of flared skirts worn by female bodies in different human gaits and movement postures, compared the appearance forms and folds of virtual and actual flared skirts, and concluded that virtual fitting could help people to design the silhouette of clothes and predict the experience of wearing them. Oh and Ryu 10 used Optitex Runway 12.0 to investigate how virtual flared dresses of multiple fabrics differ from actual dresses, analyzing the impact of material properties on virtual clothing in a 3D virtual wearing system. In general, previous researches on the simulated appearance of virtual clothing mainly focused on skirts, mainly wavy skirts, and evaluation indexes between real dresses and virtual dresses include folds and contours.…”
