Beginning with the analysis of the ink-wash dynamic diffusion mechanism

an improved Cellular Automata(CA) model based on the characteristic factors that can reflect the effect of ink-wash diffusion more naturally is presented in this paper.The ink-accommodating and ink-adhering concept for the ink status of the fiber cell is introduced for the first time.The evolvement rules of the ink-particle movement and the water evaporating are simplified and established by the quantizing status.The simulation results show that the randomicity and motility of the ink-wash diffusion are visibly enhanced by this CA model and the simulated effect is more real than former models.At the same time

the widespread applicability for the simulated effect of ink-wash diffusion is provided by this CA method.The various 3D and styles of ink-wash brush effect will be digitally realized by 3D modeling and writing brush models.
