Topology-free cut-and-paste editing over meshes

Hongbo Fu, Chiew-Lan Tai, Hongxin Zhang
Geometric Modeling and Processing, 2004. Proceedings  
Existing cut-and-paste editing methods over meshes are inapplicable to regions with non-zero genus. To overcome this drawback, we propose a novel method in this paper.  ...  Therefore, our elegant method not only can eliminate the dependence on the topology of the selected feature, but also reduces the distortion effectively during pasting.  ...  Adopting this scheme guarantees that our cut-and-paste algorithm is topologically free.  ...

Detail-replicating shape stretching

2011 The Visual Computer  
[25] proposed a topology-free cut-and-paste editing method that deals with regions of non-zero genus while minimizing any possible distortions caused by incompatible geometry between source and target  ...  The only options they have is either apply a local free form deformation (FFD) and risk distorting any surface details, or manually cut and paste different parts from the mesh that can be time consuming  ...  Each vertex x i on the mesh is iteratively updated by adding the scaled discrete Laplacian ∆x i and by assigning scalar weights w ij to each neighbor of x i such that j w ij = 1, the discrete Laplacian  ...

Laplacian surface editing

2004 Symposium on geometry processing : [proceedings]. Symposium on Geometry Processing  
We argue that geometric detail is an intrinsic property of a surface and that, consequently, surface editing is best performed by operating over an intrinsic surface representation.  ...  Based on this Laplacian representation, we develop useful editing operations: interactive free-form deformation in a region of interest based on the transformation of a handle, transfer and mixing of geometric  ...  This work was supported in part by the German Israel Foundation (GIF) and by grants from the Israel Science Foundation (founded by the Israel Academy of Sciences and Humanities) and the Israeli Ministry  ...

Prop-cut: A mesh cutting method based on Tikhonov regularization

Hongxin Zhang, Juan Wang
2009 2009 11th IEEE International Conference on Computer-Aided Design and Computer Graphics  
By integrating the proposed mesh cutout tool, we also demonstrate a simple sketch-based mesh editing system. In our system the cutting results can be further deformed, morphed, or cut-and-pasted.  ...  Users first assign foreground and background seed faces on a given triangular mesh by sketch lines. Then the system computes a scalar field across the mesh.  ...  Sketch based mesh editing system In this section, we describe our novel framework of mesh (and/or multi-mesh) cutting-and-pasting.  ...

Free-form Sketch [article]

Haixiong Wang, Lee Markosian
2007 Sketch-Based Interfaces and Modeling  
A key difference is that a layered mesh lets you edit the shape and structure of the mesh at any level of the hierarchy, through the notion of shape primitives organized in a dependency network.  ...  Like subdivision surfaces, layered meshes provide a multiresolution hierarchy of meshes.  ...  Due to the representation, arbitrary topology models can be robustly created and edited. Topology edits are harder to make in Free-Form Sketch, as the user edits the mesh structure explicitly.  ...
