Neither the topology, the presence of boundaries, nor the geometry of M are assumed to be known in advance -all are inferred automatically from the data. This problem naturally arises in a variety of practical situations such as range scanning an object from multiple view points, recovery of biological shapes from two-dimensional slices, and interactive surface sketching.
