  abstract = {This paper presents a new algorithm for smoothly blending be-
              tween two 2-D polygonal shapes. The algorithm is based on a
              physical model wherein one of the shapes is considered to be con-
              structed of wire, and a solution is found whereby the first shape
              can be bent and/or stretched into the second shape with a min-
              imum amount of work. The resulting solution tends to associate
              regions on the two shapes which look alike. If the two poly- gons
              have m and n vertices respectively, the algorithm is O(mn). The
              algorithm avoids local shape inversions in which intermediate
              polygons self-intersect, if such a solution exists.},
