Abstract
Graphics editors have recently come into wide use. But for displaying high quality images, a more powerful tool has been desired. This paper proposes a useful display method for Chinese calligraphy, traditional Japanese ink painting called sumie, and watercolor painting. The method comprises techniques to express the outlines of a brush stroke and to vary shades of color. That is, the outlines of a brush stroke are modeled using piecewise Bézier curves, and the variation of gray shade inside of the outline are defined by Bézier functions. This method provides effective characteristics of a brush stroke such as shade variation, the scratchin ess produced by dry brush, and blotchiness caused by the diffusion of ink.
