Claim 21:
22. An apparatus for data processing, the apparatus comprising:
means for providing a 3D model of a person's head;
means for defining second measurement points on a standard head of a parametric head model;
means for fitting the parametric head model to the 3D model of the person's head;
means for setting first measurement points on the 3D model of the head by transferring the second measurement points defined on the parametric head model after the process of fitting the parametric head model to the 3D model of the head;
providing fitting guidelines of the spectacle frame; and
means for fitting a model of the spectacle frame to the 3D model of the head based on the determined first measurement points and the fitting guidelines,
wherein the parametric head model has a greater smoothness than the 3D model of the person's head.
