We describe two new shape operators that superimpose wrinkles on top of a smooth NURBS surface. Previous research studying wrinkles focused mostly on cloth modeling or in animations, which are driven more by visual realism, but allow large elastic deformations. Our operators generate wrinkle-shaped deformations in a region of a smooth surface along a given boundary based on a few basic parametr...

In this paper, we present an experimental work using a MOCAP system and an iterative minimization technique to compute damping parameters and to measure their contribution for the simulation of cloth in free fall movement. Energy damping is an important phenomenon to consider for the 3D simulation of warp and weft materials, since it has a great influence on the animation realism. This phenomen...

In this paper we present a computer vision algorithm for estimating cloth parameters for mod-eling. In an analysis-by-synthesis manner, the algorithm compares the drape of the model with the range data and searches for the best t. It can be applied to any physics-based cloth model. The motivating application is fashion design using CAD systems, but the ability of the algorithm to estimate the s...

In this paper we present an algorithm for analysis of the range data of cloth drapes. The goal of the analysis is estimation of parameters for modeling and the geometry of the underlying object. In an analysis-by-synthesis manner, the algorithm compares the drape of the model with the range data and searches for the best t. It can be applied to any physics-based cloth model. The motivating appl...

In this paper, a method of generating the three-dimensional knitting clothes shapes is described. First, a method of representation of the cloth is described. In this method, a cloth is represented by a mesh, which is a set of vertexes. Next, a method of generating the cloth shapes is described. The cloth covers three-dimensional objects. To generate the shapes, vertexes of the mesh are moved w...

Adsorption of pollutants on activated carbon is an effective air pollution control technique. In this study, a strong and non-uniform electric field was applied over an activated carbon fiber cloth. The adsorption kinetic of several organic compounds (Acetone, Acetaldehyde, Benzene, Cyclohexane, Ethanol, Methyl Ethyl Ketone, Toluene, 1-Propanol) on the activated carbon cloth was evaluated in th...

A patient developed severe hemolytic anemia one year after insertion of a cloth-covered aortic valve prosthesis (Starr-Edwards No. 2320). The cloth over the three struts was disrupted but showed coverage with mostly organized collagen. Hemolysis stopped after replacement with a porcine heterograft. Fabric wear seems to augment the hemolysis in patients with cloth-covered artificial valves.
