Simulating Chinese calligraphy and painting in real time.

摘要

This thesis presents a real-time simulation of Chinese calligraphy and ink painting. The approach includes an ink diffusion model, a multi-layer paper model, a brush model, and the simulation of special effects. The ink flow model is based on a new algorithm simulating dynamic ink diffusion into absorbent painting paper enabling the simulation of the washing out effect. An efficient geometric brush model which includes the brush movement mechanism has also been developed.; The main contribution of the thesis is the interactive system for generating better quality and more efficient simulated calligraphy than existing systems. A wide range of brush and ink effects such as flying white and dry brush effect and irregular edges and back run effects can be simulated with the system. Another major contribution of the thesis is the introduction of the adaptive dynamic ink flow model. This new model is capable of simulate the real physical process of ink diffusion and deposition. Experimental results and analysis confirm that the models and algorithms presented are efficient which lead to the real-time results.
