As an interactive geometry editing technique,mesh deformation plays an important role in geometry modeling and computer animation. Detail-preserving mesh deformation, especially differential domain deformation techniques gains high interests in the computer graphics community in recent years. Combined with recent advancements on mesh deformation methods classified into skeletal deformation, surface deformation, and space deformation, this paper provides a systematic survey on this area, trying to give a comprehensive introduction and comparison to those typical mesh deformation methods from their algorithmic principles, advantages and limitations. Furthermore, the opportunities of future research in mesh deformation are discussed.
