Abstract: In order to realize the computer simulation of Half-Dry Stroke in Chinese
painting, based on the technique of writing, the effect of Half-Dry Stroke is proposed, which is
divided into silkiness and plaques respectively, including the decrease of ink, the determination of
Half-Dry Stroke areas and the generation of stroke. By detecting ink volume of the stroke model,
the reaction of stroke split in the insufficient area is yielded. Based on the main-stroke, a certain
number of sub-strokes with identical model are superposed, then the effect of emulating Half-Dry
Stroke is realized.

Key words: computer art, Chinese painting simulation, half-dry stroke effect, stroke
superposing, writing model
