Accurate simulation of draped fabric sheets with nonlinear modeling

Abstract

This paper reports a numerical approach, based on a nonlinear particle spring model and a collision detection procedure, to simulate the shape of a draped cloth, or a flexible sheet, together with a simple but precise three-dimensional shape reconstruction method for real fabric applications. The latter is utilized to verify the accuracy of the proposed drape simulation model. The drapes of four types of fabric on a cylinder are simulated, and the results are compared with the reconstructed shapes of the same cloths; the results show an excellent agreement. The simulation model is further used to calculate the shapes of skirts of different materials and sizes, and the effects of fabric parameters, length, and waist size are numerically investigated. The results reveal that under the same conditions, the behaviors of different materials are affected by their properties in terms of stiffness coefficients of the springs. The silk skirt looks soft and fluttering; the outer contour curve of the skirt simulated for the polyester fabric appears relatively smoother, but the shape of the cotton skirt seems to be stiffer. The skirt made of fabric of 10% cotton and 90% polyester combines the characteristics of the polyester and cotton fabric.

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

“…They reported that the fabric's physical parameters have a strong effect on the fabric drape form, such as the tensile, elongation, and stiffness. The material differential effect was observed under the same condition of simulation [11]. Miguel et al tested the fitting of two fabrics using a normal skirt to assess the fitting of a jacket, the fabrics are similar, but the first fabric is one layer and the second is a double layer [12].…”

“…al., demonstrated that the drape analyses are required because the drape coefficient test results (the reflection of drapped sample shadow, as Cusick drape meter standard method) are not sufficient to describe well the fabric drape behavior on the human body on garment simulation software [10]. Chen et al studied the difference between the drape of square and circular samples and make a comparison [11]. Also, they made several ways of capturing the sample draped, with three methods; the 1st one is capturing the normal photo, the 2nd is 3D scanning and the 3rd is reconstructing the sample drapped on a virtual cylinder object on 3D software.…”

The Relationship Between FAST Mechanical Properties, Fabric Drape Coefficient and 3D Simulated Flared Skirt

“…3 different way of the draped samples are captured 2D photo, 3D scanning and reconstructed virtually on 3D software. It is reported that, the mechanical properties have a strong relationship with the drape coefficient, in both situation real and virtual 11 .…”

Review of cloth modeling and simulation for virtual fitting

“…Effects of draping: (a) photographs of real cloth items; (b) reconstructed three-dimensional images and (c) simulation results. Case 1: cotton fiber; Case 2: fibrilia; Case 3: polyester fiber; Case 4: 10% cotton and 90% polyester fiber 24.…”

“…Thirdly, researchers have also launched studies on virtual fitting based on human posture, such as Han X et al 5 and Bowen et al., 22 which helped to optimize the effect of simulation following posture for real-time fitting. Finally, the collision problem has been studied by researchers early on, such as Ling et al., 23 Yong et al., 6 and Chen et al., 24 and a variety of theoretical approaches have been proposed to reduce the computational effort and solve the cloth penetration problem. The cloth modeling and simulation technology is made up of multiple links, of which these four perspectives have research coherence and are processed sequentially.…”
