This paper present an application to the facial animation of the D.O.G.M.A. (Deformation Of Geometrical Model Animated) model. We described an order-controlled animation, where a first set of orders simulate the contraction of different facial muscles, a second some facial expressions. The main interest of this method is the manipulation of faces with various shape. Since the deformation given by the animation model DOGMA are space deformations, the only necessity is a hierarchical structuring of the different face component. With this method the same facial animation order can easily be used for various objects with different shapes, if they present the same hierarchical structuring.
