基于笔法模型的国画一笔多色模拟

为了完善“一笔多色”国画技法效果的计算机模拟,提出了基于笔法的多色效果仿真.通过建立笔锋模型,改变子笔道的粗细(中锋)或将多个子笔道偏移一定位置(侧锋)进行叠加,避免了逐点计算笔道中的颜色的复杂过程,提高了运算速度.中锋、侧锋是根据笔杆与纸面的夹角进行判断的,计算机智能笔法就是通过中锋和侧锋的转换来实现的,从而产生两种不同笔法的一笔多色模拟效果.

Simulation of brushstroke multi-color in Chinese painting based on technique of writing model

In order to improve the computer simulation of the brushstroke multi-color in Chinese painting,this paper proposes the multi-color effect emulate based on the technique of writing.By establishing a stroke model,the thick or thin of sub-stroke（center writing） is changed,or several sub-strokes（side writing） are superposed which offset a certain distance.Thus the complex process of calculating the color in the stroke area point by point is avoided and the running speed is enhanced.The center writing and the side writing are determined by the angle between brush and paper,and the intelligent technique of writing is realized when the center writing and the side writing are interchanged.Then the effect of brushstroke multi-color emulate is produced by two different techniques of writing.
