1. A method in a computer system for generating a 3D image of an object, the method comprising: providing a 3D model of an object, the 3D model including a 3D image of a standard object and parameters indicating variations of an individual object; receiving a 2D image of the object; locating feature points of the 2D image of the object; calculating parameters that map the located feature points of the 2D image to feature points of a 2D representation of the 3D image of the standard object; and setting points of the 3D image of the object using the provided 3D model and the calculated parameters.
