| 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. |
