摘要
一种新的曲面纹理合成技术被提出,它采用求最小割集来解决块拼接时的接缝走样问题。算法在预处理期对模型的三维网格进行了重建,使其规则并且建立网格点与参数化栅格采样后的图像点一一对应的关系,无论对合成的速度和质量都有很大的提高。提出了在曲面上进行纹理粘贴的算法,对于渲染存在不完整性的自然物体取得了较好的效果。
A new texture synthesis algorithm over arbitrary surfaces is proposed in this paper, which uses graph cut to solve aliasing problem. The algorithm also remeshes the surface, makes the surface regular and construct good mapping from surface vertex to image pixel after grid sampling of parameterization. These operations significantly improve both speed and quality of the synthesis. The last part proposed an algorithm about painting textures over surface, which has compelling performance in rendering nature object with imperfections.
