This paper presents an efficient and realistic approach to seam the 2D panels together into a 3D garment mesh. Our main goal is to be able to seam any kind of panels together robotically without considering the variation of style and geometry. In particular, we are discussing difficult situations with respect to deformations and variation of sewing forces Based on the mass-spring model, two-dimensional panels are seamed together along the seams and then three-dimensional garment meshes are built. Our main contribution is that we add five pairs of sewing forces avoiding undesirable sharp folds. Our approach provides a useful design tool to create 3D garment mesh directly in the 3D space through 2D patterns. It is reasonably easy to incorporate our 3D mesh construction techniques into existing 3D graphics systems because we use standard triangular mesh structures and force-based mass-spring model for cloth animation.

Theoretical Analysis of the Factors Affecting Splice Loss During Fabric Spreading

Journal of China Textile University(English Edition) 2000年第2期17卷 65-68页

作者： Hui Chi Leung Patrick and NG sau fun FrencyInstitute of Textiles & Clothing, The Hong Kong Polytechnic University The Hong Kong Polytechnic Univ Hong Kong Hong Kong

Material utilization is mainly concerned by industrialpractitioners since it contributes to minimize the totalproduction costs for garment manufacturing. Apart fromthe marker loss, splice loss (the fabric loss during thejoining of different fabric rolls) is one of the primarycauses of fabric loss, but it has not been considered spe-cifically in the past literatures. The amount of splice lossduring fabric spreading is governed by various factors in-cluding the marker length, the number of fabric rolls,and the number of splicing intervals for laying-up. Inour study, these three effects on splice loss during fabricspreading were computed and analysed.

A joint computational-experimental study of intracranial aneurysms:Importance of the aspect ratio

引用

Journal of Hydrodynamics 2016年第3期28卷 462-472页

作者： Simon Sui-Man LAI Abraham Yik-sau tang Anderson Chun-On TSANG Gilberto Ka-Kit LEUNG Alfred Cheuk-Hang YU Kwok Wing CHOW Department of Electrical and Electronic Engineering University of Hong Kong Hong Kong China Department of Mechanical Engineering University of Hong Kong Hong Kong China Department of Surgery Li Ka Shing Faculty of Medicine University of Hong Kong Hong Kong China Department of Electrical and Computer Engineering University of Waterloo Ontario Canada

Rupture of a cerebral aneurysm （abnormal swelling of blood vessel in the brain） will cause subarachnoid hemorrhage, and will result in an alarming rate of mortality and morbidity. A joint computational-experimental study is conducted to assess the importance of the aspect ratio in the dynamics of blood flow. The aspect ratio is defined here to be the ratio of the height of the aneurysm to the linear dimension of the neck. Idealized models of such aneurysms located near a bifurcation point were investigated. Numerical simulations for hemodynamic properties like shear stress and flow rate were performed. The computational results were verified experimentally with specially fabricated phantoms, blood mimicking fluid and Doppler ultrasound imaging. Excellent agreements were obtained. Two features are highlighted, providing information in the intensely debated link between rupture risk and geometric factors. On increasing the aspect ratios, firstly, a jet impinging on the distal part of the neck can be observed, and secondly, a region of positive shear stress gradient can be found there. Furthermore, computational analyses for four patient-specific models were conducted to correlate with the results of idealized models and to provide further clinical insight.
