Surface Reconstruction from Unorganized Points Using Subdivision Techniques

A new approach to reconstruct subdivision surfaces from unorganized points of arbitrary topology is proposed. Reconstructed surfaces are piecewise smooth subdivision surfaces without trimming and sewing. The main idea is to utilize the local characteristic of Loop subdivision to adjust, optimize and adaptive subdivide control mesh to let the subdivision surface fit the data points. Examples demonstrated that the algorithm is efficient and robust, can effectively preserve the detail characteristics of data points.
