Abstract: The problem of reconstruction to triangular surfaces from given contours is considered. A new approach that the main idea is to employ discrete distance fields enhanced with correspondence information is presented. It solves the branching problem and correspondence problem. The methods of connecting feather nodes from two consecutive slices are presented. Through recursive producing medial axis, the surfaces of reconstruction become smooth. This can solve the branching problem by creating intermediate contours where adjacent contours differ too much.
