ÐThis paper discusses the self-collision avoidance problem in simulating the dynamic behavior of deformable cloth. It is not an easy task to simulate realistically the response of cloth in various types of complicated self-collisions. In this paper, the bounding box technique in addition to ordinary prechecking for collision detection is used to avoid self-collision. Instead of avoiding self-co...

An analysis of one of the approaches to cloth modeling is carried out in this paper. The real 3D structure of the cloth at micro level is considered and the lighting simulation with the accuracy control is provided. The simulation result in BSDF form is a full description of optical properties of the cloth sample. It allows us to produce the “far view” of the cloth accurately and fast.

Realistic simulation and manipulation of virtual cloth based on energy minimization techniques require higher computations. A model realizing force as well as shape to manipulate the virtual cloth demands even more computational cost. Mesh resolution of cloth has a great effect on the computational cost of cloth simulation. Therefore, granularity of mesh must be chosen in a manner that represen...

The animation and rendering of crowds of realistically clothed characters presents a difficult challenge in computer graphics, which is further exacerbated when real-time frame rates are required. To date, due to real-time constraints, standard skinning methods have been used to animate the clothes of individuals in real-time crowds, which does not create the appropriate secondary motion for fl...

Any cloth simulation system needs efficient numerical methods for integrating the equations that describe the mechanical behavior of the discrete representation of the cloth. Choosing the adequate method should be done with full knowledge of the advantages and weaknesses of the main techniques. This paper presents a quantitative comparison of the efficiency of the most common integration techni...

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...

Cloth simulation has a long history, starting almost three decades ago. Thanks to the continuous increase of computation speed of computers, real-time simulation of clothes has become very recently possible. The research on real-time clothes has really begun few years ago when researchers have started simulating simple garments such as flags or tablecloths. Nowadays, the research aims at propos...

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...
