| 摘 要： | 为了快速有效地进行水彩非真实感绘制,综合考虑了工具材质的物理特性和视觉特征,提出一种基于模拟退火算法的水彩画计算机仿真方法.通过定义颜料颗粒解、产生函数和冷却进度表,并且利用解空间的迭代计算模拟水彩动静态属性.为了增加绘制效果真实感,利用Ashikhmin纹理映射算法合成水彩纸的自然背景纹理,并修正和迁移了光学库伯卡-芒克模型以融合纹理基质和颜料涂层,仿真了水彩肌理性特征.实验结果表明了该方法的有效性.

| Abstract: | To simulate watercolor efficiently,a kind of watercolor computer simulation method based on simulated annealing algorithm is presented with the analysis tool and material physical properties and visual features.Firstly,with defining pigment solutions,produce function and cooling schedules,watercolor dynamic and static attribute is simulated by using the solution space iterative calculation.Then,in order to increase rendering photorealistic,synthesize the nature texture of watercolor paper by Ashikhmin algorithm and migrate optic KM theory to fusion textural effect of watercolor paper.Finally,performances of the proposed method are demonstrated by the application. |
