1. An apparatus for obtaining points of a surface of an anatomical feature comprising:

  • a base adapted to be secured to an anatomical feature;

    a spherical joint supported by the base, the spherical joint having a ball member rotatable in at least two rotational degrees of freedom relative to the base and having a center of rotation fixed relative to the base;

    a distance-measurement device connected to the ball member such that a distance-measurement axis of the distance-measurement device passes through said center of rotation of the ball member, the distance-measurement device configured for providing a distance of any point of the surface intersecting the distance-measurement axis; and

    at least one receptacle configured to receive an inertial sensor unit for determining an orientation of the distance-measurement device;

    whereby a position of any point is obtained using said distance and an orientation of the distance-measurement device as connected to the ball member at a measurement of said any point.
