obtaining multiple sets of three-dimensional scan data of said object;

finding a seed triangle in said scan data to form a triangulated mesh;

pivoting a ball around an edge of said triangulated mesh until a new point in said scan data is hit by said ball, wherein said edge and said new point define a new triangle;

adding said new triangle to said triangulated mesh;

selecting a new edge of said triangulated mesh and repeating said finding, pivoting and adding steps until all points in said scan data have been used or a valid seed triangle cannot be formed.
