摘要 为了克服凸长和复杂网格较难克隆的问题,提出一种基于扩展中值坐标的交互式网格编辑方法.首先由用户选择源网格中感兴趣的区域,使用垂直投影参数化方法将其映射为二维区域,并将映射后的网格顶点二维拓扑信息保存为图像元放置于目标网格相应位置;然后通过扩展中值坐标参数和外部的边界环,在被粘贴的图像元基础上恢复出三维信息;最终粘贴网格部分被变形使得与目标网格光滑拼接.该方法采用GPU对网格复制进行加速.实验结果表明,文中方法能够在三维模型之间实时地复制、替换任意不规则网格区域. In order to clone protrusive and complex mesh effectively, this paper presents an interactive mesh editing approach based on extended mean value coordinates. Firstly, the user selects region of interest on the source mesh. The region is mapped into a 2D parametric domain using vertical projection parameterization and abstracted into image texel. Then it is placed to the user assigned location on the target mesh. Secondly, 3D information of the stitched mesh is retrieved by extended mean value coordinates parameter and the boundary difference of the region. Finally, the stitched mesh is deformed to match the target mesh. We use GPU to speed up the mesh cloning. Experimental results show our approach can copy arbitrary irregular mesh regions between two 3D models.
