Abstract

An online garment model reconstruction method is proposed using the axial deformation to simulate the various garment models to display the wearing effect under different sizes. The garment model is classified into three categories according to the structural features. The main sections and key points are determined based on the existing dimensional features. Inverse operation and radial weight are used in the garment deformation. Texture mapping is applied to the model reconstruction result to obtain a new model with clothing patterns. An online system is developed and garment models with multiple scales are applied to adapt to various devices. The reconstruction results are compared and analyzed, which proves that the method proposed can realize real-time 3D reconstruction of garment models with the changing sizes on the web page.

Highlights

With a remarkable rise in people’s living standards and aesthetic understanding, mass-produced garments have become unable to meet the individual needs of consumers
In order to verify the effectiveness of this method, the garment model reconstruction with circumference and length changing is made on an initial garment model
Texture mapping technology is applied in garment model reconstruction, by which the pattern bitmaps are fitted well with models of different sizes for a better display effect

Summary

Introduction

With a remarkable rise in people’s living standards and aesthetic understanding, mass-produced garments have become unable to meet the individual needs of consumers. The multi-layer and hybrid dimension drove by several factors such as size, human body, and garment restraint was introduced to treat the garment model deformation[10] Both of the methods above used 2D to 3D mixed dimensional mapping but the mesh model needed to be constructed which is complex. The section information of key parts is obtained from the given garment model and the control points are calculated. To facilitate the calculation of key points and size-based deformation, it is important to determine the main parameter sections, which are used for model layering. If O1 and O2 change to O1’ and O2’ because of the section deformation or the length changing, the new projection point S’ is presented as the third formula in Formula (9), where x’O1, y’O1, z’O1 and x’O2, y’O2, z’O2 are coordinates of O1’ and O2’. The new circumference points are derived from Formula (11)
