Wire deformers are like the armatures used by sculptors to shape objects. With a wire deformer, you use one or more NURBS curves to change the shape of objects. For a quick example of creating a wire deformer, see What are sculpt deformers?.

Wire deformers let you change the shapes of deformable objects with one or more NURBS curves. In character setup, wire deformers are especially useful for setting up lip and eyebrow deformations. To create further wrinkling effects, you can also use the wrinkle deformer. Wire deformers can also be useful for shaping NURBS or polygonal objects during modeling.
