1. A method comprising:

  • obtaining a data set of a first point cloud and a data set of a second point cloud;

    identifying a portion of geometry defined by each respective data set which describes a substantially similar geometric shape;

    computing a transformation such that the portion of geometry in each data set align to substantially minimize alignment error;

    applying the transformation to the first point cloud to register it relative to the second point cloud;

    obtaining a data set of at least a third point cloud;

    assigning one of the point clouds to be an anchor; and

    applying a transformation to each other print cloud to register it relative to the anchor.
