A quaternary subdivision scheme with two parameters is proposed by using reverse construc-tion and multiplying smoothing factor.The continuity of this quaternary subdivision scheme is ana-lyzed by generator polynomial.The specific parameter value intervals satisfying C0-C3 continuity are provided.Numerical examples demonstrate the influence of each parameter on the curve formation,and the dynamic parameter iteration process describes the change details of the curve generation.
