[Abstract]:As a traditional form of art, the simulation of Chinese ink painting has gradually become a challenging subject in the field of computer application research. Since the development of non-realistic rendering technology in the field of computer graphics in the mid-1990s, the rendering of non-realistic ink painting is also a research branch in this field. It is an urgent problem to perfect the relevant artistic style and to create Chinese ink painting with both shapes and spirits with interactive drawing technology. The techniques of Chinese ink painting are random, which is not easy to imitate. This paper focuses on the simulation and realization of the ink and wash art effects of the Chinese ink painting techniques, and expounds their application categories. Based on the traditional artists' more commonly used strokes and their characteristics of simulation drawing, based on the previous research, we put forward their own improved algorithm, in order to pursue more realistic Chinese ink painting artistic effect. In order to realize the ideal ink painting effect, this paper analyzes and studies the drawing techniques of the non-realistic ink painting and the painters' brushwork, the characteristics of using ink water and the different effects produced by the texture features of different paper. This paper mainly puts forward the computer simulation research of two kinds of brushwork freehand brushwork techniques. The unfathomable artistic effect of Chinese ink painting originates from the interaction between the ink itself, the painting tool brush and the spatial structure mechanism of Xuan paper, etc. On the basis of previous studies, the internal structure of Xuan paper fiber was constructed by using the physical model of the dynamic diffusion mechanism of ink and water, and the diffusion behavior of liquid was simulated, and the diffusion rules of ink and wash were improved. Through the interaction between the motion of water particle and ink particle and the fiber cell, we can realize the phenomenon of edge dark color and diffusive region burr, etc. In this paper, the probabilistic model of variable parameter coefficient of three-point region is used to simulate a kind of water-ink diffusion technique, and different styles of ink diffusion are formed by adjusting the parameters. A new geometric method based on virtual rotatable lateral front and multi-cluster mane pen model is proposed to simulate the white phenomenon of the traditional brush, which needs to obtain the information of pen pressure and rotation direction. The application of OpenGL texture mapping technology combined to make the final effect better. Finally, the experimental results show that the original edge of the ink and wash paintings drawn by the method proposed in this paper is dark at the beginning, the final diffusion of burr feeling, and the obvious phenomenon of dry brush flying white, and the simulation of brush texture characteristics is relatively ideal. It reproduces the artistic effect of imitating non-realistic ink painting and adds a unique form to the inheritance and retention of Chinese traditional art form.
