Three-Dimension Mesh Model Progressive Sharing

A three-dimension mesh model progressive sharing method is proposed. The so-called (t1, t2,..., tr; n)-threshold sharing encodes an original three-dimension mesh model into n model-shares, where t1 ≤ t2 ≤ ...≤ tr ≤ n. The t1 model-shares can provide the least quantity for revealing the smallest part of the original three-dimension mesh model. More model-shares are received, the revealed part becomes larger. Because tr model-shares can reveal the original three-dimension mesh model with very little distortion, the method is thus called fault-tolerance.
