Abstract:A ternary subdivision scheme based on arbitrary triangular control mesh is proposed and analyzed in this paper. The sufficient conditions of the convergence property and G^1 continuity property of the new subdivision scheme are obtained and proved. In comparison with the existing ternary interpolatory subdivision schemes of surface, the presented subdivision scheme is simple and has a better local property; the corresponding smooth subdivision surfaces can also be generated quickly.
Keywords:triangular mesh  subdivision surface  ternary subdivision  interpolation
