Claim 0:
1. A computer-implemented method for defining a primal reference frame for a three-dimensional (3D) model, comprising:
identifying a plurality of landmarks on the 3D model, wherein the landmarks define a cloud of points;
creating a mirror-image copy of the cloud of points;
iteratively translating and/or rotating the mirror-image copy until fitted with the cloud of points;
superimposing the mirror-image copy and the cloud of points to create a single group of points; and
calculating a plane of symmetry that divides the single group of points, wherein iteratively translating and/or rotating the mirror-image copy until fitted with the cloud of points comprises calculating a weighted Procrustes distance between the mirror-image copy and the cloud of points.
