In the existing work, character modelling and animation are two separate tasks. After a character model is built, a lot of time and efforts are still required to animate the character model. Ordinary differential equation-based surface modelling and animation using physically based deformable curves to define and deform skin surfaces of 3D character models. With such a technique, character modelling and animation can be integrated into a unified framework by introducing time-dependent varying force fields into ordinary differential equations. This paper addresses the issue of determination of the force fields and proposes three models, i. e. linear transformation model, interpolation model and extrapolation model, to obtain time-dependent varying force fields. Some application examples are presented which demonstrates the force fields obtained from the three models create believable skin deformations of character models.
