In recent years, three-dimensional computer graphics (3DCG) technology has been applied in various fields such as AR / VR technology, movies, games, and virtual fitting of clothes. One of the problems is the problem of contact between clothes and other objects (such as the body). In this paper, we focused on that problem. The methods verified at that time are the Euler method, the FB Euler method, and the Runge-Kutta method. In this paper, we verified each simple animation using the above three methods. As a result of the verification, animation with the Euler method or Runge-Kutta method shows contact with the body, clothes moving away from the body, and heavy movement, etc.The FB Euler method creates a simple but stable animation Was completed. However, problems such as the need to manually change parameters and the large amount of calculation were raised. In addition, other issues such as the study of numerical calculation method and contact force calculation method other than the method verified this time and the study of texture mapping method to skirt were mentioned. In this paper, we were able to create simple animations, but there were still many issues such as the number of mass points and the reproducibility of the cloth, and there were many issues to be improved. Therefore, we want to pursue future research and aim for more realistic reproduction and practical research.
