A method of scaling a three-dimensional input model (100) in a three-dimensional input space into a three- dimensional output model (200) which fits in a predetermined three- dimensional output space (104) is disclosed. The scaling is such that a first input surface (106) in the three-dimensional input space, having a first distance to a viewpoint, is projected to a first output surface (110) in the predetermined three-dimensional output space by applying a first scaling factor and whereby a second input surface (108) in the three-dimensional input space, having a second distance to the viewpoint, which is smaller than the first distance, is projected to a second output surface (112) in the predetermined three-dimensional space, by applying a second scaling factor which is larger than the first scaling factor.
