Existing cut-and-paste editing methods over meshes areinapplicable to regions with non-zero genus. To overcomethis drawback, we propose a novel method in this paper.Firstly, a base surface passing through the boundary vertices of the selected region is constructed using the boundary triangulation technique. Considering the connectivitybetween the neighboring vertices, a new detail encodingtechnique is then presented based on surface parameterization. Finally, the detail representation is transferred onto the target surface via the base surface. This strategy of creating a base surface as a detail carrier allows us to pastefeatures of non-zero genus onto the target surface. By taking the physical relationship of adjacent vertices into account, our detail encoding method produces more naturaland less distorted results. Therefore, our elegant methodnot only can eliminate the dependence on the topology ofthe selected feature, but also reduces the distortion effectively during pasting.
