Achieving realistic skin deformation efficiently is a very important task for character animation. With the development of skin deformation, the efficiency and effectiveness of character modelling and animation have been obviously enhanced. In this paper, we survey the recent literature on skin deformation according to three types of approaches: purely geometric, physics-based, and data driven. Especially we focus on the work since 2009. We review the problems they primarily tackles, the methodologies they applies, and the advantages and disadvantages they have. At last, we discuss directions for future research.
