Claim 14:
15. A computer-implemented method for virtual fitting of a spectacle frame, the method comprising:
providing a 3D model of a person's head;
providing a parametric head model having second measurement points;
fitting the parametric head model to the 3D model of the person's head;
determining first measurement points on the 3D model of the person's head based on the second measurement points defined on the parametric head model;
wherein the second measurement points are defined on a standard head of the parametric head model, and
wherein determining the first measurement points comprises transferring second features defined on the standard head to the fitted parametric head model in accordance with the fitting; and
fitting a model of the spectacle frame to the 3D model of the person's head based on the determined first measurement points,
wherein the parametric head model has a greater smoothness than the 3D model of the person's head.
