Due to its practical use in animation and image editing, two‐dimensional shape deformation has received great attention during the past decades. The traditional paradigms, spreading local modifications over the whole shape, will cause a global deformation. For the simultaneous realization of the local control and preservation of the rigidity of the shape, a novel deformation method is proposed for point, skeleton, and cage handles. Our framework can be accomplished in terms of the minimization of the improved as‐rigid‐as‐possible energy with local and smooth penalties, named locally controlled as‐rigid‐as‐possible energy. The visually pleasing experiment results demonstrate the success of our method in two‐dimensional character deformation.
