Claim 15:
16. A method comprising:
detecting one or more intersection edges by:
generating a mesh around a point associated with a physical object, which is not a silhouette edge point, of a scan pattern grid with neighbor points forming shared edges between regions of the mesh; and
computing a normal gradient across an individual shared edge to determine whether the point is lying on an intersection edge of a smooth surface; and

detecting one or more silhouette edges using the scan pattern grid and a point cloud data, wherein detecting the one or more silhouette edges comprises:
determining mixed pixels, between two objects, from the scan pattern grid; and
distinguishing silhouette edge points of the two objects from the mixed pixels by determining whether a point in the scan pattern grid is on one of the two objects.
