Abstract:

Digitalization of the inkwash diffusion effect is a key in simulating ink-wash by computer graphics. Based on an analysis of the relationship between water, ink and rice paper, an improved method that is token the mechanism of ink-wash dynamic diffusion by these relations is presented. Assuming that ink-wash consists of water and ink molecules and by constructing a rice paper structure, a simulation model using a particle system is established. The process of dynamic diffusion and its simulation are simplified. Simulation experiments on Maya show that the diffusion effect of ink-wash using this model is more realistic. Randomness and mobility of the ink-wash dynamic diffusion is visibly improved. In this way, controllability of particles is enhanced, and the amount of computation is reduced. This model is more flexible for the implementation of various styles of ink-wash simulation.
