Feature-Based Mesh Editing

Very few sketch-based design systems are concerned with editing low-poly models, or with sketching control meshes for subdivision surfaces.. Much early work was on recogniz- ing

The extraction of ridges and valleys combined with curvature optimization provide us with a number of editing operations that maintain features and prevent unwanted features

The user can perform edits on an automatically-generated simplified version of an input shape using As-rigid-as-possible surface modeling, and the edit is propagated to the

We have discussed sketch-based segmentation editing in the contour domain and we have shown how variational inter- polation can be used for efficient editing of tumor segmen- tations

Figure 3: Direct meshing of the point cloud using Poisson surface reconstruction produces a mesh with an arbitrary distribution of triangles as can be seen in many parts of the

Based on the operation tree, the model can be continuously adapted using parallel vertex split and edge collapse operations.. Our proposed algorithm can be divided in two
