Procedural approach to generate real time motions of cloth

The deformation of cloth is one of the essential aspects to increase the sense of reality in the area of VR (Virtual Reality) or game programming. In contrast, when a character wearing clothes or hanging a flag moves abruptly and rapidly, it is not easy to express the natural movement of the cloth in a limited time. In this paper, the position-based approximation method that considers the nonlinearity which is a vital feature in the realistic deformation of cloth and responds to the abrupt and frequent external forces as well is proposed. Our method that processes the non-linear deformation properties geometrically can produce a fast and stable cloth animation. In addition, it reflects the physical attributes to the geometrical relation so that the visibly-plausible movement of cloth can be generated. As a result, cloth animation that is stable despite the fast movement of a car and realistic to the external environmental change such as the driving direction of the car or the surface of the road, can be created.
