A robust real-time mesh editing approach is proposed

which allows us to select precise regions for parameterization

and realize seamless cloning of the 3D surface geometry. First we select the region of interest(ROI) using a paintbrush interface

and ascertain the region for parameterization by traversing the mesh using half edge structures combined with a seed fill algorithm. The distance limitation is attached from the center of paintbrush to the vertexes of the ROI. Then

the mean value coordinates without cage are used for shape deformation. Finally

the source mesh patch is cloned seamlessly onto a target mesh. Experimental results demonstrate that the proposed method outperforms previous related mesh editing techniques on protuberant meshes with high curvature Furthermore

the method can be processed in real-time and it is rather robust. Mesh editing approach using mean value coordinates combined with Poisson equation is robust and real-time capable

which allows us to select precise region for parameterization and realize seamless cloning of 3D surface geometry. It performs more robust compared with the existing mesh cloning methods.
