1. A method of determining by a computing device the progress of a 3-dimensional scan of an object by a 3D scanner comprising the steps of:

  • a) providing a dummy model approximating in shape to the object being scanned and comprising a 3D point cloud with a normal at each point obtained from the 3D scanner;

    b) selecting keyframes from the 3-dimensional scan of the object obtained from the 3D scanner that are used for surface reconstruction;

    c) determining whether a point in the 3D point cloud has been scanned from each of the selected keyframes; and

    d) calculating by use of the computing device the percentage of scanned points to the total number of points in the 3D point cloud to determine the progress of the 3-dimensional scan of the object by the 3D scanner.
