Physical-based Model of Ink Diffusion in Chinese Paintings

Chinese ink painting is a traditional art that is over three thousand years old. It is a type of non-photorealistic rendering. However, research on Chinese ink painting is scarce. Simulating the behavior of Chinese ink is challenging work because ink moves in a complex manner. This paper presents a new method for simulating ink diffusion based on observation and analysis. The proposed method can simulate various expressions of tones on different types of paper. The elucidation of the effect of mixing simulated strokes made by different kinds of brushes is an important contribution of the method. Finally, the simulated results are compared with real ink painting.
