The idea is developed from the cross-sectional method, and inherits its basic deformation strategy. The main contribution of our method is a generalized cross-sections method, with which the complex processes for construction of cross-sectional contours, skin representation, and welding are elided, while the details of an existent body model are retained. The conception and subdivision method for generalized cross-sections are introduced, and the interpolation method is employed to improve the results of shoulder deformation. Finally, the results of our method are given, which are realistic and satisfy real-time applications.
