1. A method of partitioning an image of a bone into a plurality of regions, the method comprising the acts of: using a medical imaging machine to obtain a plurality of volumetric image slices of the bone; employing selective resolution over different areas of the bone in the image slices; using at least one computer to generate a plurality of spline curves associated with the bone; verifying that at least one of the plurality of spline curves follow a surface of the bone; and using at least one computer to create a three dimensional (3D) mesh representation based upon the at least one of the plurality of spline curves.
