Abstract:

This paper proposes and implements an approach to smooth B-Spline surface reconstruction based on the mesh model. In the investigation , a method to define and optimize the feature lines of the mesh model is studied and implemented. Then , a set of interactive editing tools are provided for users to freely construct the final quadrilateral patch topology model which suits the original design intent. Finally , a smooth B-spline surface is reconstructed by synthetically considering the fitting accuracy , the smoothness and the continuousness. Experimental results demonstrate that the proposed algorithm meets the requirements for reconstruction efficiency and surface fitting quality in reverse engineering.

Key words: reverse engineering, smooth B-spline surface reconstruction, mesh model, feature line, quadrilateral patch segmentation
