Space deformation is an important technique for shape modification and flexible animation generation in geometric modeling and computer animation．A novel multiresolution space deformation method is proposed in the paper which is controlled by subdivision surface of arbitrary topology．It supplies a solution for the complex shape edit while method is fast enough to achieve realtime interaction．Several subdivision schemes are adopted and compared in the method．Experimental cdteria are given on how to determine appropriate subdivision scheme and subdivision depth．To achieve realtime interaction，parameterization is accelerated through space-subdivision and deformation is evaluated locally．All of above algorithms are integrated into a space deformation prototype system．The system has the functions of multiresolution space deformation and abundant control mesh generation methods．
