Analysis of Polygonal Computer Model Parameters and Influence on Fabric Drape Simulation

Abstract

Contemporary CAD systems enable 3D clothing simulation for the purpose of predicting the appearance and behavior of conventional and intelligent clothing in real conditions. The physical and mechanical properties of the fabric and the simulation parameters play an important role in this issue. The paper presents an analysis of the parameters of the polygonal computer model that affect fabric drape simulation. Experimental research on physical and mechanical properties were performed for nine fabrics. For this purpose, the values of the parameters for the tensile, bending, shear, and compression properties were determined at low loads, while the complex deformations were analyzed using Cusick drape meter devices. The fabric drape simulations were performed using the 2D/3D CAD system for a computer clothing design on a disk model, corresponding to real testing on the drape tester in order to allow a correlation analysis between the values of drape parameters of the simulated fabrics and the realistically measured values for each fabric. Each fabric was simulated as a polygonal model with a variable related to the side length of the polygon to analyze the influence of the polygon size, i.e., mesh density, on the model behavior in the simulation. Based on the simulated fabric drape shape, the values of the areas within the curves necessary to calculate the drape coefficients of the simulated fabrics were determined in the program for 3D modelling. The results were statistically processed and correlations between the values of the drape coefficients and the optimal parameters for simulating certain physical and mechanical properties of the fabric were determined. The results showed that the mesh density of the polygonal model is an important parameter for the simulation results.

Evaluation Model of Product Shape Design Scheme Based on Fuzzy Genetic Algorithm Mining Spatial Association Rules

“…e modular development and configuration of product family are divided into two aspects, namely, the construction of complex product main structure, and the use of it to carry out configuration and optimization. Multifactor modeling and module division include four aspects: the construction of correlation relations among views, the construction of fine-grained view model of products, the characterization of coupling factors and the correlation of multidimensional coupling factors, and the analysis of view ordered structure [16]. Modular design must plan product platform system structure by means of identification and analysis of multidimensional coupling factors or systematic coupling factors [17].…”

Review of cloth modeling and simulation for virtual fitting

“…This would allow the visualization of the dynamic deformation of clothes. Therefore, not only the cloth draping characteristics, 48 yarn structure, etc., should be considered, but also other aspects, such as the movement of the human body. An example is the simulation of a crease in clothing caused by bending a leg.…”

Drape of Composite Structures Made of Textile and 3D Printed Geometries

“…An important practical application of the drape images, which has become necessary in recent years, is their use for three-dimensional visualization and simulation in the analysis of textile fabrics. According to Petrak et al [15], an important parameter for adjustment in the 3D simulation of garments is the density of the used grid of the polygonal model. By optimally choosing this density, the resulting three-dimensional model will be simple enough and will carry enough information about the condition of the drapery.…”
