3D object metamorphosis through energy minimisation

This paper presents a technique for smoothly blending some special categories of three dimensional polygonal objects. Polygon blending is usually considered a two-part process: generating vertex correspondences and interpolating between corresponding vertices to create the intermediate polygons. This paper considers the problem of automatic vertex correspondence determination. The proposed algorithm is based on the work of Sederberg and Greenwood [SED92]. The resulting solution tends to associate regions of the two objects which look alike
