Abstract: The main problems of parametric methods in composite surface reconstruction are analyzed. A novel surface reconstruction scheme of recursive interpolating subdivision is presented to calculate the interpolated vertices from the arbitrary to pological initial mesh formed by the discrete measurement points of the physical model. A quad-tree typed data structure is designed to store all the necessary information of subdivision process. The presented examples of complicated surface recon-struction can verify that the parameterization of the discrete measurement points and the surface conjunction between patches can be avoided. A novel effective approach for compli-cated surface reconstruction is put forward.
