Interactive editing of arbitrary sub-meshes

We present a novel approach to interactively edit and deform polygonal meshes. The idea is to confine editing operations to mesh regions of interest, called submeshes, leaving others untouched as much as possible. Classical editing operations such as scaling, shearing, and rotation can be then applied to each submesh instead of the whole mesh. Analogously, intuitive deformation operations (e.g. tapering and twisting) as required for animation systems can be applied to submeshes, allowing the user to have control on the local deformations of mesh objects.
