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.展开更多

A 46-year-old man presented with protruded sharp swelling left side of neck, X-rays and CT scan of the neck showed a needle migrating from the pyriform fossa to the skin. Carotid angiography was also done to see the relations of foreign body with great vessels. Transcutaneous removal of foreign body was done under general anesthesia. The migrated foreign body was a sewing needle which patient unknowingly swallowed two days back. Migrated ingested foreign bodies from the upper digestive tract have the potential to cause life-threatening complications. Cases of spontaneous expulsion of ingested foreign bodies to the skin of the neck are quite rare.展开更多
