Mesh Editing
A key problem with meshes is how to effectively edit them. We can
obviously move a single vertex around at will. But reshaping models by
repeatedly moving single vertices is tedious (to put it mildly). Here
we’ll discuss a few approaches for conveniently editing the shape of a
meshed surfaces.

First lecture
When we pull on part of the mesh, we’ll want some part of the surface to
deform along with our action. We’ll

Second lecture
We’ve seen Laplacian-type structures in smoothing, parameterization, and
compression. It turns out, they crop up in editing as well.

Another major vein of work on mesh editing has been to support
sketch-based interfaces to modeling.
