Abstract
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.
