Claim 22:
23. An apparatus for data processing, the apparatus comprising:
means for providing a 3D model of a person's head;
means for providing a parametric head model having second measurement points;
means for fitting a parametric head model to the 3D model of the person's head;
means for determining first measurement points based on the second measurement points defined on the parametric head model, and fitting the parametric head model to the 3D model of the head,
wherein the second measurement points are defined on a standard head of the parametric head model,
wherein the means for determining the first measurement points comprise means for transferring the second features defined on the standard head to the fitted parametric head model in accordance with the fitting,
wherein the means for determining the first measurement points additionally comprise means for projecting the second measurement points onto the 3D model of the head; and

means for fitting a model of a spectacle frame to the 3D model of the head based on the determined first measurement points.
