We consider the problem of autonomous robotic laundry folding, and propose a solution to the perception and manipulation challenges inherent to the task. At the core of our approach is a quasi-static cloth model which allows us to neglect the complex dynamics of cloth under significant parts of the state space, allowing us to reason instead in terms of simple geometry. We present an algorithm w...

Computer-aided cloth design is one of the quite popular research themes in recent years, and the authenticity of it’s simulated result and the efficiency of simulation are two main research questions. The cloth behavior not only determines the authenticity of simulation, but also influences the efficiency of simulation. So 3D virtual clothing is simulated and rendered by the way of 2D patternin...

We present an interactive system for intuitive manipulation of dynamic cloth using multi-touch technology. The system consists of two main modes that can be toggled anytime, namely cloth creation mode and cloth manipulation mode. In cloth creation mode, the user creates pieces of cloth by drawing each desired shape directly onto the scene using simple swipe gestures. The system automatically ge...

We present an efficient and stable framework, called Unified Intersection Resolver (UIR), for cloth simulation systems where not only impending collisions but also pre-existing penetrations often arise. These two types of collisions are handled in a unified manner, by detecting edge-face intersections first and then forming penetration stencils to be resolved iteratively. A stencil is a quadrup...

We present a new collision resolution scheme for cloth collisions. Our main concern is to find dynamically convincing resolutions, i.e. positions and velocities of cloth elements, for any kinds of collisions occuring in cloth simulation (cloth-cloth, cloth-rigid, and cloth-cloth-rigid). We define our cloth surface as connected faces of mass particles where each particle is controlled by its int...

Cloth modeling and simulation has gained significant momentum in recent years due to advances in computational hardware and software. Cloth plays an important role not only in daily life, but also in special scenarios such as firefighter’s cloth and space suits. There are special requirements such as protection capability of the human body and mobility after the firefighters or astronauts wear ...

This paper implements efficient techniques for cloth simulation in the area of cloth model, numerical integration, collision detection and response. The whole procedure combines the accurate bending model with implicit integration and collision response. Collision response remains a serious difficulty in cloth simulation, especially with implicit integration. We propose a general scheme that in...

OBJECTIVE The aim of this study was to compare the efficacy of cloth masks to medical masks in hospital healthcare workers (HCWs). The null hypothesis is that there is no difference between medical masks and cloth masks. SETTING 14 secondary-level/tertiary-level hospitals in Hanoi, Vietnam. PARTICIPANTS 1607 hospital HCWs aged ≥18 years working full-time in selected high-risk wards. INTER...

Even though a particle model based on the mechanical properties of woven cloth has been proposed by Breen et al[l], there are problems to describe cloth behavior precisely and reflect cloth dynamics. In this paper, we describe a precise relationship between measured mechanical properties of cloth and the particle model. Moreover, a collision model describing the rotation as well as move of part...
