一种多笔触各向异性梵高风格油画的渲染方法

摘要

为使计算机模拟出更逼真的流体风格(涡旋状)梵高油画特效,本文提出了一种多尺度各向异性偏微分方程的模拟方法,该方法利用P-M和J.Weickert加权模型在滤噪音时产生的虚假条纹来模拟梵高油画的涡旋状,并在油画绘制时给图像平坦区域加入高斯噪音和采用多尺度弧形笔刷的技术来处理整个渲染过程.实验结果表明:本方法除了很好的模拟了梵高油画的抽象效果外,还增加了油画的层次感和更多的涡旋状.%To make the computer simulation of a more realistic fluid style (vortex) Van Gogh painting effects,this paper proposes a multi-scale anisotropic partial differential equation of the simulation method,the method using P-M and JWeickert weighted model in filtering the noise produced when the false stripes to simulate the Van Gogh painting of spirals,and joined to the flat areas when drawing oil painting gaussian noise and using multi-scale curved brush technique to handle the whole rendering process.xperimental results show that this method is very good to simulate the Van Gogh painting abstract effect,also added administrative levels feeling of the painting and more vortex.
