Physical modeling of "Xuan" paper in the simulation of Chinese ink-wash drawing

In order to simulate the typical artistic effects of Chinese ink-wash drawing, a new simulation approach based on physical modeling is presented. A controllable physical paper model is built to imitate the real fibre mesh of "Xuan", based on which the simulation system perfectly achieves the effect-simulating of Chinese ink-wash drawing. As the basic modeling unit, we first propose the concept of paper cell, by pass simulating the random fibre distribution of "Xuan", this approach successfully simulated the "particle phenomenon" and the irregular diffusion edge. The experiment results indicate that the physical paper model can simulate many different kinds of "Xuan" by controlling parameters such as density, water-absorbability and texture, so very natural and similar-to-real simulation effects are achieved.
