A data structure for representing an animated model of a head/face which may be rendered as an image on a display screen comprising: a map having a partial three dimensional surface defined as a mesh of interconnected nodes, the surface lying generally in a single plane in a peripheral region and being raised out of that plane in a central region corresponding to the topology of a face; a two dimensional image of a head/face which is viewed from the front which includes a face, surrounding hair and neck portion, and can be conformed to the surface of the map to provide a partial 3 dimensional model of the face in which the face has contours corresponding to the faces features and in which the hair overlies the flat peripheral region; at least one user defined co-ordinate corresponding to the location of a part of a facial feature in the model; and at least one facial feature which is located on the map in a position defined by the user defined co-ordinate. |
