1. A method comprising: segmenting an animation wireframe in a depth map indicating a face region and a non-face region, the depth map being a 2D image where each pixel represents an absolute distance or a relative distance between a face model and a viewpoint, wherein the animation wireframe has three-dimensional range data and color data; and scaling, via a processor, the animation wireframe proportionally, based on the color data and on a plurality of distances between feature pairs within a plurality of features, the plurality of features being within the three-dimensional range data, wherein said scaling is performed for a horizontal slice of said animation wireframe using a scaling factor based on the distance between a corresponding feature pair, and wherein said animation wireframe comprises a plurality of horizontal slices and each horizontal slice of said animation wireframe is scaled according to a corresponding scaling factor based on the distance between the corresponding feature pair.
