Subdivision Surface Approximation of Data Points and Polygon Models

This paper describes a general method for reconstruction of a subdivision surface from polygon model or a set of scattered data points. The basic idea is to use the subdivision limit position to adapt the control mesh of the subdivision surface to the data points. This method is not a time consuming process involving global optimization. It does, however, fail to capture local characteristics of input model. Consequently, the proposed method is not suitable for generating a surface that precisely interpolates the input model, but it will be useful for quickly generating one that captures the overall shape constituted by the input model.
