国画一笔多色的计算机模拟

Computer Simulation of Multi-Color Effect in Chinese Painting

针对国画的笔道颜色分布会随运笔的缓疾、力度轻重而异的特点,提出了运用多个单色笔道叠加的方法,实现了"一笔多色"国画技法效果的计算机模拟。重点探讨了叠加笔道的数量、多色笔道的实时显示、多色笔道的整体删除等问题。笔道叠加算法避免了逐点填充笔道的复杂过程,保证了笔道颜色渐变在效率最优的情况下达到最大分辨率。仿真算法表明,绘制效果既保留了原笔划钩提顿挫的力度特性,又巧妙地解决了笔划中色彩过渡的问题,整体效果逼真细腻。

Multi-color effect in Chinese Painting has a special feature of color distribution in stroke which would be varied by the speed and power of using brush and couldn’t be solved by the existing method of Texture Mapping.To simulate its complex color gradation,the method of multi-color stroke by superposition of general strokes of different colors is presented.Some problems are discussed,such as the number calculation of general strokes in a multi-color stroke,the real time display and integer deleting of the ...
