Free-form surface reconstruction from scattered points based on SOFM and NURBS

A geometric modeling method,which based on NURBS from scattered points,was presented.By using Unigraphics the original surface was built,on which several curves were divided and a large number of scattered points on the curves were generated stochastically.By the clustering of scattered points with SOFM(Self-Organizing Feature Map),the NURBS were built and the free-form surface reconstruction was accomplished.The error between the reconstructed surface and the original surface was analyzed through simulation.Results showed that the proposed method could reconstruct curved surface efficiently which could fit the original surface accurately.
