Abstract: The invention relates to a method for coding animation parameters for a character (A) with which are associated morphological values, said animation parameters comprising a translation parameter associated with at least one part of said character (A), characterized in that to code an intrinsic translation of said part of said character (A) by a translation vector, said translation parameter contains a value which is dependent on said vector and on one of said morphological values.

Abstract: A method of animating a scene graph (M), which comprises steps for: creating (e1) an animation graph instance (G) comprising animation modules (MA1, . . . , MA10) and composition modules (MC1, . . . , MC4) organized in a tree structure, the animation modules being leaves of subtrees of the graph and the composition modules being used to compose results of their child modules, the latter being either animation or composition modules indiscriminately, and executing (e3) the animation by executing in turn the animation and composition modules of the graph, so that the execution of a composition module uses the results of the executions of its child modules.
