METHOD FOR SEPARATING TRIANGULAR MESH SURFACE OF TOOTH FROM TRIANGULAR MESH SURFACE OF DENTAL

摘要

A method for separating the triangular mesh surface of a tooth from the triangular mesh surface of a dental is provided by the present invention, which integrates three advantages of accuracy, efficiency and smooth boundary, through the operations: picking the dental region to be separated interactively, preliminarily separating of the region growing, generating a space control curve automatically, positioning precisely, generating a separate line projection, optimizing of the smoothing of the separate line and so on, the separation of the surface triangular mesh of the tooth is finally realized.
