%X It is an active researching area to reconstruct the model of 3-dimensional object from cross-sectional images and to display its visible surfaces. In this paper, the theory and the method of reconstructing the model of 3-D object and displaving its visible surface from X-CT imaqes are studied. Giving the number of segment points, a polygonal approximation method is presented. Then a fast contour interpolating method is introduced. The reconstructed liver voxel set is displayed with the depth-only shading method and the depth gradient shading method, the result is satisfactory. The software is written in C language and runs on PC-VISION image processing system.
