Abstract

This paper describes a novel approach to simulating Chinese calligraphy for digital image purposes. The approach includes an ink diffusion model, a multi-layer paper model, a brush model, and the simulation of special effects. Special attention is given to the ink diffusion effect which is of importance in Chinese calligraphy. When the ink is deposited onto absorbent paper, it spreads outside the original border of a stroke since the flow of water will transport carbon particles along the capillary tubes found in the paper. The ink flow model is based on a new algorithm simulating dynamic ink diffusion into absorbent paper. In this capillary network based paper model, the pressure at each node can be obtained from Darcy’s law applied to the ink used in the calligraphy on each edge and it is proportional to the density of capillaries. The deposition layer of the paper is furthermore used to simulate the deposition of carbon particles into the paper and it is also used to simulate the washing out effects. Ink effects such as irregular edges and back run effect can also be simulated. The system is efficient and can create realistic Chinese calligraphy in real-time.
