Abstract
In the field of computer graphics, many studies on how to represent "cloth" of "clothing, food and housing" have been widely conducted and used for various video works in games, movies and so on. Realistic cloth dynamics stems mainly from that of its wrinkles and creases. Existing research attempts at cloth simulation can generally be divided into two approaches; physics-based, which pursues the physical correctness of cloth dynamics, and position-based, which relies on simpler models to simulate "plausible looking" of cloth. The former taxes complex computation and complicated parameter adjustment for more physical simulation results. In this article, we focused rather on the latter approach. Indeed, we proposed a new method for simulating the creases on cloth by taking full advantage of Position Based Dynamics (abbreviated to PBD). PBD approaches do not strictly obey the real world physics, but can simulate cloth with a relatively simpler algorithm with more abstract parameter adjustment. They are more suitable for real time applications such as video games because it becomes more important to take into account "plausible looking and ease of parameter adjustments".
