A new method is presented to the B-spline surface presentation of an object defined by a set of parallel slices. For the application of B-spline inversion procedure, the methods about the data points generated are mainly introduced. The mesh of the data points is generated from interpolation curves of the vertex of the contour, which enable the interpolating surface to approximate the original object. It has the advantage that the reconstructed surface keep the smoothness in total longitudinal direction. The proposed method is also capable of handling the branching problem. Several experimental results corroborate the theory. The results show the image with high fidelity and the rendering speed are satisfactory and pleasing.
