In this paper, a new solution to the problem for reconstructing the surface of 3D objects over a set of cross-sectional contours is proposed. An algorithm for single branch contours connection, which is based on the closest local polar angle method, is first presented. Then an approach to solving the branching problem is proposed. Next, a method for surface shading is given. Finally, these methods have been applied to the reconstruction of the external surface of a complex shaped object such as the cellar region of human brain. The results show that the presented methods are practical and satisfactory.
