ABSTRACT

A system of techniques is proposed for reconstructing the original object from multi-layered cross-section data including open contour lines and for displaying the inner structure as well as the outside using a stereoscopic semi-transparent image and cut-away views. The procedure is divided into three steps: 1) selection/construction of contour lines for each cross-section, 2) reconstruction of the object based on the contour line information including cutting away part of the reconstructed object with a convex polyhedron, and 3) display of the reconstructed image. Control parameters are provided to allow easy and reliable observation of multi-layered structures.
